Strategic Budget Optimization through Marketing Mix Modeling (MMM)

Stop guessing which channels drive growth. Join Isabella Velásquez and Daniel Chen for this end-to-end workflow demo on modeling marketing spend, building ‘what-if’ scenario planners in Shiny, and deploying automated Quarto reports that give non-technical stakeholders a clear, data-backed view of ROI. We will explore: The Workflow Architecture: A look at the “plumbing” required to move from data to insights. The Interface: Wrapping an existing model in a Shiny dashboard for real-time “what-if” scenario planning. The Delivery: Automating communication via Quarto reports to keep stakeholders aligned. The Deployment: Using Posit Connect to turn your code into an accessible business asset for leaders. This workflow demo grew out of the incredible energy at our recent Data Science Hangout with Ryan Timpe at LEGO.

Driving Shiny adoption by removing friction | Jonathan Lin | Data Science Hangout

ADD THE DATA SCIENCE HANGOUT TO YOUR CALENDAR HERE: https://pos.it/dsh - All are welcome! We’d love to see you! We were recently joined by Jonathan Lin, Adviser of Data Science and AI at Ovintiv, to chat about scaling data science infrastructure with Kubernetes, the “show, don’t tell” method for leadership buy-in, creating internal handbooks to support users, and even a little chat around navigating a sparse job market. In this Hangout, we explore Jon’s approach to driving adoption and scaling impact without becoming a bottleneck. He discusses moving from simple virtual machines to using Kubernetes to manage memory for over 900 users and 60 publishers (wow!!). John also details how he built a comprehensive internal “handbook” to answer repeated questions, allowing him to support a growing community of R and Python users while encouraging self-service learning.

The one skill AI can’t replace | Alexander Schacht | Data Science Hangout

ADD THE DATA SCIENCE HANGOUT TO YOUR CALENDAR HERE: https://pos.it/dsh - All are welcome! We’d love to see you! We were recently joined by Alexander Schacht, Senior Director at Cytel and Host of The Effective Statistician, to chat about the tensions between technical and executive work, how to increase visibility in your organization, and ethical considerations in data science (specifically regarding patient data). In this Hangout, we explore the “engine vs. wheels” analogy for data professionals. Alexander explains that while technical skills (the engine) are vital, they are useless without communication and leadership skills (the wheels) to put that power on the road. He shares advice on how to stop being the “p-value police” and instead build trust by understanding stakeholders’ fears, hopes, and business goals.

Hackathons for education, not competition | Allissa Dillman | Data Science Hangout

ADD THE DATA SCIENCE HANGOUT TO YOUR CALENDAR HERE: https://pos.it/dsh - All are welcome! We’d love to see you! We were recently joined by Allissa Dillman, Founder and CEO at Biodata Sage LLC, to chat about her transition from NIH to entrepreneurship, the importance of social learning and community in coding (Libby’s favorite topic!!), organizing hackathons for education rather than just competition, and strategies for networking regardless of whether you are an introvert or an extrovert. In this Hangout, we explore the power of social learning and community. Allissa discusses why she believes we learn and grow more confidently when working with others rather than in isolation, noting how shared struggles can actually help overcome imposter syndrome. She also shares her philosophy on running hackathons that prioritize networking and experiential learning over high-pressure competition, and talks about how she navigated the leap from a stable job to starting your own business.

Polars: The Blazing Fast Python Framework for Modern Clinical Trial Data Exploration

Polars: The Blazing Fast Python Framework for Modern Clinical Trial Data Exploration - Michael Chow, Jeroen Janssens Abstract: Clinical trials generate complex and standards driven datasets that can slow down traditional data processing tools. This workshop introduces Polars, a cutting-edge Python DataFrame library engineered with a high-performance backend and the Apache Arrow columnar format for blazingly fast data manipulation. Attendees will learn how Polars lays the foundation for the pharmaverse-py, streamlining the data clinical workflow from database querying and complex data wrangling to the potential task of prepping data for regulatory Tables, Figures, and Listings (TFLs). Discover the ‘delightful’ Polars API and how its speed dramatically accelerates both exploratory and regid data tasks in pharmaceutical drug development. The workshop is led by Michael Chow, a Python developer at Posit who is a key contributor to open-source data tools, notably helping to launch the data presentation library Great Tables, and focusing on bringing efficient data analysis patterns to Python.

The dessert-first approach to teaching data science | Mine Cetinkaya-Rundel | Data Science Hangout

ADD THE DATA SCIENCE HANGOUT TO YOUR CALENDAR HERE: https://pos.it/dsh - All are welcome! We’d love to see you! We were recently joined by Mine Çetinkaya-Rundel, Professor of the Practice at Duke University and Senior Developer Advocate at Posit PBC, to chat about her cake-first teaching philosophy, strategies for communicating technical results to non-technical stakeholders, and career advice on learning new tools later in life, among other things. In this Hangout, we explore Mine’s unique approach to explaining difficult topics to students. She describes her method as “let them eat cake first,” where she shows learners the final, compelling result (like a visualization) before teaching them the “ingredients” or technical steps required to get there. By establishing the motivation and the destination first, she finds students are more willing to invest the effort into learning the necessary coding and data cleaning logic.

Teaching out loud and becoming StatQuest | Josh Starmer | Data Science Hangout

ADD THE DATA SCIENCE HANGOUT TO YOUR CALENDAR HERE: https://pos.it/dsh - All are welcome! We’d love to see you! We were recently joined by Josh Starmer, Founder and Creator of the massively popular YouTube channel StatQuest with Josh Starmer, to chat about his process for simplifying complex technical topics, overcoming imposter syndrome and feeling cringe, the enduring value of foundational statistics over fleeting AI trends, and how to use AI tools responsibly without sacrificing true understanding. In this Hangout, we explore Josh’s unique approach to teaching and learning difficult concepts. He reveals that he specifically avoids watching other videos on a subject to ensure his explanations remain original. Instead, he focuses on finding the “simplest possible example” that still highlights the method’s utility—such as creating a neural network with only three data points to visualize the math. Josh emphasizes that the hardest part of his work is constantly asking, “Can I make it simpler?” and extracting the essence of an equation so that learners can “feel” the statistics rather than just memorizing them.

Daniel Chen - LLMs, Chatbots, and Dashboards_ Visualize Your Data with Natural Language - PyData

LLMs have a lot of hype around them these days. Let’s demystify how they work and see how we can put them in context for data science use. As data scientists, we want to make sure our results are inspectable, reliable, reproducible, and replicable. We already have many tools to help us in this front. However, LLMs provide a new challenge; we may not always be given the same results back from a query. This means trying to work out areas where LLMs excel in, and use those behaviors in our data science artifacts. This talk will introduce you to LLms, the Chatlas package, and how they can be integrated into a Shiny to create an AI-powered dashboard. We’ll see how we can leverage the tasks LLMs are good at to better our data science products

How Open Source, Python and AI Are Shaping the Data Future with Wes McKinney

The future of analytics isn’t just about bigger models — it’s about building smarter, more interoperable data systems. Wes McKinney, Principal Architect of Posit PBC, Chief Scientist of Voltron Data and a General Partner at Composed Ventures, joins us to explore how the modern data stack is evolving and what it means for the future of analytics. Wes reflects on his journey building pandas and Apache Arrow, sharing how open-source ecosystems grow, transform and shape the way organizations work with data today. Wes also highlights the rising importance of semantic layers, agentic workflows and defensive coding practices as teams embrace AI-driven development. Key Takeaways: 00:00 Introduction. 02:32 Wes didn’t expect pandas to drive AI but he recognized Python’s unrealized potential. 05:09 A lucky convergence helped Python’s tools snowball into the AI standard. 10:40 Early big data focused on essentials, not the interoperable stacks we rely on today. 15:44 The composable data stack grew through bottom-up, grassroots open-source momentum. 21:56 Many “data science” roles ultimately became business intelligence and dashboard work. 25:24 Complex statistical work still depends on human judgment, not fully autonomous agents. 30:27 Frontier models retrieve table data reliably, while smaller models fail dramatically. 35:16 Better models and coding agents shifted Wes from an AI skeptic to an adopter. 40:07 AI-driven code demands stronger testing and review to avoid costly failures. 45:14 An AI-built finance project ballooned, revealing how agents inflate codebases.

Simon Couch - Practical AI for data science

Practical AI for data science (Simon Couch) Abstract: While most discourse about AI focuses on glamorous, ungrounded applications, data scientists spend most of their days tackling unglamorous problems in sensitive data. Integrated thoughtfully, LLMs are quite useful in practice for all sorts of everyday data science tasks, even when restricted to secure deployments that protect proprietary information. At Posit, our work on ellmer and related R packages has focused on enabling these practical uses. This talk will outline three practical AI use-cases—structured data extraction, tool calling, and coding—and offer guidance on getting started with LLMs when your data and code is confidential. Presented at the 2025 R/Pharma Conference Europe/US Track.

Rodrigo Silva Ferreira-When Rivers Speak Analyzing Massive Water Quality Datasets-PyData Boston 2025

Rivers have long been storytellers of human history. From the Nile to the Yangtze, they have shaped trade, migration, settlement, and the rise of civilizations. They reveal the traces of human ambition… and the costs of it. Today, from the Charles to the Golden Gate, US rivers continue to tell stories, especially through data. Over the past decades, extensive water quality monitoring efforts have generated vast public datasets: millions of measurements of pH, dissolved oxygen, temperature, and conductivity collected across the country. These records are more than environmental snapshots; they are archives of political priorities, regulatory choices, and ecological disruptions. Ultimately, they are evidence of how societies interact with their environments, often unevenly. In this talk, I’ll explore how Python and modern data workflows can help us “listen” to these stories at scale. Using the United States Geological Survey (USGS) Water Data APIs and Remote SSH in Positron, I’ll process terabytes of sensor data spanning several years and regions. I’ll demonstrate that, while Parquet and DuckDB enable scalable exploration of historical records, using Remote SSH is paramount in order to enable large-scale data analysis. By doing so, I hope to answer some analytical questions that can surface patterns linked to industrial growth, regulatory shifts, and climate change. By treating rivers as both ecological systems and social mirrors, we can begin to see how environmental data encodes histories of inequality, resilience, and transformation. Whether your interest lies in data engineering, environmental analytics, or the human dimensions of climate and infrastructure, this talk will explore topics at the intersection of environmental science, will offer both technical methods and sociological lenses to understand the stories rivers continue to tell

Bayesian MMM and silly side projects | Ryan Timpe | Data Science Hangout

ADD THE DATA SCIENCE HANGOUT TO YOUR CALENDAR HERE: https://pos.it/dsh - All are welcome! We’d love to see you! We were recently joined by Ryan Timpe, a Lead Data Scientist, to chat about Marketing Mix Modeling (MMM), silly data science side projects like brickr (see the link below to his 2020 posit::conf() talk), the benefits of working out loud, and using LLMs (Large Language Models) for data science coding (something he gave a whole talk about at posit::conf(2025)). In this Hangout, we explore a bit of what Ryan does, including Marketing Mix Modeling (MMM) and helping business partners better use their data. He shared that his work utilizes Bayesian methods to manage the complexity and high seasonality of his data, especially the Q4 holiday-buying spikes seen in most retail sales data. Using Bayesian priors helps keep the models within constraints and prevents overfitting. The foundation of the internal MMM package that Ryan developed uses tidy models, and you can check out the link to his 2023 posit::conf() talk to hear more about his model pipeline! The theme here is that Ryan gives lots of great talks - go check them out!

The skydiver to data scientist pipeline | Kevin Dalton | Data Science Hangout

ADD THE DATA SCIENCE HANGOUT TO YOUR CALENDAR HERE: https://pos.it/dsh - All are welcome! We’d love to see you! We were recently joined by Kevin Dalton, Senior Data Scientist at Great American Insurance Group, to chat about data science in the insurance industry, MLOps and productionalization strategies, Bayesian modeling, and career development. In this Hangout, we explore MLOps and productionalization strategies, especially the distinction between “little P” and “big P” production. Kevin explained that “small p” production involves internal dashboards, interactive applications, or analytics reports used to support the research process and assess the business, generally having a lower risk profile. In contrast, “big P” production refers to ML models deployed for inference in core business systems, which demand strict Service Level Agreements (SLAs). Kevin noted that the industry is moving towards automated, cloud-centric, real-time inference engines, although production systems can still be as simple as running a notebook over new data.

Keeping LLMs in Their Lane: Focused AI for Data Science and Research

From R+AI 2025, hosted by R Consortium Keynote LLMs are powerful, flexible, easy-to-use… and often wrong. This is a dangerous combination, especially for data analysis and scientific research, where correctness and reproducibility are core requirements. Fortunately, it turns out that by carefully applying LLMs to narrower use cases, we can turn them into surprisingly reliable assistants that accelerate and enhance, rather than undermine, scientific work. This is not just theory—I’ll showcase working examples of seamlessly integrating LLMs into analytic workflows, helping data scientists build interactive, intelligent applications without needing to be web developers. You’ll see firsthand how keeping LLMs focused lets us leverage their “intelligence” in a way that’s practical, rigorous, and reproducible. Bio Joe Cheng is the CTO and first employee at Posit, PBC (formerly known as RStudio), where he helped create the RStudio IDE, Shiny web framework, and Databot agent for exploratory data analysis.

How to use pointblank to understand, validate, and document your data

R/Medicine Webinar This workshop focused on the data quality and data documentation workflows that the pointblank package makes possible. The speaker Richard Iannone used functions that allowed us to: quickly understand a new dataset validate tabular data using rules that are based on our understanding of the data fully document a table by describing its variables and other important details The pointblank package was created to scale from small validation problems (“Let’s make certain this table fits my expectations before moving on”) to very large (“Let’s validate these 35 database tables every day and ensure data quality is maintained”) and Ionnone delved into all sorts of data quality scenarios so the viewer will be comfortable using this package in their organization. Data documentation is seemingly and unfortunately less common in organizations (maybe even less than the practice of data validation). We’ll learn all about how this doesn’t have to be a tedious chore. The pointblank package allows you to create informative and beautiful data documentation that will help others understand what’s in all those tables that are so vital to an organization. Speaker Richard Iannone, Software Engineer, Posit, PBC Rich is a software engineer at Posit that enjoys creating useful R and Python packages. He trained and worked as an atmospheric scientist and discovered working with R to be a breath of fresh air compared to the Excel-based analysis workflows common in that field. Since joining Posit he has been focused on developing packages that help organizations with data management and data visualization/publishing. When not working on R and Python packages, Rich also enjoys other things like playing and listening to music, watching movies, and getting outside

Investing in community to drive organizational change | Dooti Roy | Data Science Hangout

ADD THE DATA SCIENCE HANGOUT TO YOUR CALENDAR HERE: https://pos.it/dsh - All are welcome! We’d love to see you! We were recently joined by Dooti Roy, Head of Clinical Data Science Capability Management at Boehringer Ingelheim Pharmaceuticals, to chat about organizational change in data science, investing in internal open-source community, transitioning from SAS to R, and motivating long-term learning and adoption of new tools. In this Hangout, we explore the instrumental role of internal community in driving organizational change. Dooti shared that during the preparation for the transformation process from closed source (like SAS) to R and open source, she was advised by Rachael Dempsey (creator of the DS hangout!) to invest in community and “don’t sleep on that.” Dooti reported that following this advice proved successful, as the internal community grew from the early adopters and became a safe space where colleagues help each other understand new concepts and overcome implementation challenges. This thriving community, which includes team members from the US, Europe, China, and Japan, serves as a springboard for testing new ideas, tools, and processes, generating global feedback that helps pull the institutional change forward. Maybe our favorite part, Dootie shared that strategies like naming internal meetings “beginR” (for beginner office hours) help set the right expectation, ensuring people feel comfortable asking questions without feeling afraid of appearing naive.

Scaling a shiny app to 100K monthly users | Tan Ho | Data Science Hangout

ADD THE DATA SCIENCE HANGOUT TO YOUR CALENDAR HERE: https://pos.it/dsh - All are welcome! We’d love to see you! We were recently joined by Tan Ho, Engineering manager at Teamworks Intelligence Soccer, to chat about scaling Shiny applications, working out loud and building a personal brand, defining “code in production,” and best practices for R package development. In this Hangout, we explore how Tan built a successful Shiny application that scaled to serve thousands of users, challenging the misconception that R does not scale. Tan shared his firsthand experience running the Dynasty Process Shiny app which peaked at 200,000 monthly users. He explained that the app was able to handle this load because user sessions were kept very short (around 30 seconds to a minute). Key advice for performance optimization includes focusing on small round-trip times for users, moving as much logic out of the app as possible (such as pre-computing or caching common requests), reducing the interface, and optimizing the actual queries (for instance, by rewriting them in data.table).

People over computers: engineering leadership | Elliot Murphy | Data Science Hangout

ADD THE DATA SCIENCE HANGOUT TO YOUR CALENDAR HERE: https://pos.it/dsh - All are welcome! We’d love to see you! We were recently joined by Elliot Murphy, a VP of Engineering at Posit, to chat about engineering leadership philosophy, balancing maintenance versus innovation and risk, non-traditional career paths and the value of lifelong learning, and data science tool breakdowns including Posit Cloud, Posit Connect Cloud, and shinyapps.io. In this Hangout, we explore some philosophical approaches to engineering and management, where Elliot stresses that focusing on people is more important than computers, and human relationships tend to outlast relationships with a given company or employer. Elliot discusses his role as primarily listening and synthesizing the brilliance of others, creating a supportive environment, and making space for people to take on risk and propose new ideas.

Lessons from a Broad & Varied Data Science Career | Arcenis Rojas | Data Science Hangout

ADD THE DATA SCIENCE HANGOUT TO YOUR CALENDAR HERE: https://pos.it/dsh - All are welcome! We’d love to see you! We were recently joined by Arcenis Rojas, Data Scientist at Indeed, to chat about econometrics, public vs private sector data science, navigating a varied career trajectory, AI integration in the hiring sphere, and making friends at conferences. In this Hangout, Arcenis talked about how his career journey has been wide as opposed to vertically narrow. He shared that this breadth of experience has given him confidence that he can quickly figure out any dataset. He feels it also taught him how to communicate effectively about data to people at different levels and across various domains. He also shared his tech stack at Indeed, including RStudio, Positron, AWS, Snowflake, Quarto for reporting, Shiny for apps, and Posit Connect for deploying them. An attendee asked about the impacts of AI on the job search space, and Arcenis shared the AI at Work Report (linked below) from the Indeed Hiring Lab. He says, based on research, generative AI is expected to assist many people but only replace small segments of the workforce in the coming 5-10 years, and that entry-level knowledge work is predicted to be the most highly impacted area.

Pair Programming for Sustainable Deployment | Kris Fabick | Data Science Hangout

ADD THE DATA SCIENCE HANGOUT TO YOUR CALENDAR HERE: https://pos.it/dsh - All are welcome! We’d love to see you! We were recently joined by Kris Fabick, data scientist at Nissan North America, to chat about pair programming as a mechanism for sustainable deployment, data science in supply chain operations, the challenges of integrating pair programming into a team, and even a little about Kris’s hobby, reffing soccer! In this Hangout, we explore how pair programming can serve as a mechanism for sustainable deployment. Kris explained that using pair programming is the team’s solution to successfully deploying projects in a sustainable way, especially since they have a small data science team without extensive enterprise-level tools or IT support. Pair programming creates human redundancy in a project, meaning two (or more) people are familiar with it, allowing the team to react quickly to changes in development and deployment, and ensuring that someone can cover maintenance even if the original programmer is on vacation. When pitching the investment of time to leadership, a crucial metric was cited: pair programming requires only 15% more time to implement but results in 15% fewer defects. The value proposition is that saving defects saves far more time and downstream costs than the initial investment, offering stability that was a great comfort to leadership.

You can search for the title, “Self-sufficient deployment- using pair programming to have fun and sell your solutions” and the speakers are Kris Fabick & Kristin Carr If you didn’t join live, one great discussion you missed from the zoom chat was about the difference between using AI for coding versus using human pair programming. The group discussed how “Pair programming == everyone learns MORE about the codebase” while “AI coding == everyone understands LESS about the codebase”. Chris noted that when he uses AI to help with code, he actually knows less about it and would not be able to explain the functionality to stakeholders if changes were requested. Attendees also noted that chatbots don’t show their logic or mistakes and how they back out of them, which is a valuable source of learning.

How do you manage the communication gap?” 36:50 “Do you think that AI and specifically things like Copilot might be able to replace some aspects of pair programming?” 40:59 “Do you have a piece of career advice that has really stuck with you or that you like to give people that you find impactful?” 43:36 “Have you ever done any fun data stuff related to your refereeing?” 48:36 “How do you balance the time that gets added on with pair programming with tasks that need to be done quickly?” Subscribe to posit::conf updates: https://posit.co/about/subscription-management/

Keynote: I Wrote This Talk with an LLM - Hadley Wickham

In this keynote, I’ll explore the evolving relationship between data scientists, statisticians, and large language models through a unique experiment: this entire talk was created in collaboration with an LLM. From outline to slides, from code examples to key insights, I’ll share the practical realities of using AI as a thought partner in the R ecosystem. Drawing on my experience developing tidyverse packages and teaching data science, I’ll demonstrate how LLMs can augment (rather than replace) the R user’s workflow. We’ll examine specific examples where AI assistance shines—rapid prototyping, documentation generation, and creative ideation—alongside areas where human expertise remains irreplaceable. Most importantly, I’ll reflect on what this experiment reveals about the future of our community: How might AI change the way we teach R? What new skills should we prioritize? And how can we ensure that the tools we build remain accessible and empowering for all users? Join me for this meta-exploration of AI’s role in our work, with honest reflections on both the promise and limitations of these new collaborators in our statistical computing journey. This abstract was generated by Claude Sonnet 3.7 and lightly edited by me. I used the prompt: I am Hadley Wickham, chief scientist at RStudio/Posit and I’ve been invited to give a keynote on AI at the useR conference. Please write a talk abstract for a talk entitled ‘I wrote this talk with an LLM’ https://hadley.nz/

Migrating to Open Source & the Future of Biostatistics | Beth Atkinson | Data Science Hangout

ADD THE DATA SCIENCE HANGOUT TO YOUR CALENDAR HERE: https://pos.it/dsh - All are welcome! We’d love to see you! We were recently joined by Beth Atkinson, principal biostatistician at Mayo Clinic, to chat about the challenges of migrating from SAS to R, working with diverse and noisy data types (including wearable data and omics projects), foundational tooling like RMarkdown and Quarto, and maintaining statistical fundamentals amidst the hype cycle of new tools like AI. In this Hangout, we explore the challenges of working with complex, high-volume data, like the data derived from wearable devices and medical charts. A challenge with wearable device data is that it can be super noisy, with issues like computers not syncing up, people forgetting to wear the device, or someone else wearing it. Medical chart data can be inconsistent; some things are recorded, and some are not. She also talks about the R/Medicine conference, the future of modern biostatistics, and the journey of compassionately helping an organization move from proprietary tools like SAS to open source tools like R. Beth also works on omics projects, including genomics (looking at DNA), metabolomics, exposomics (chemical exposures), and multiomics, which involves looking at all of this information together in a holistic way. We hope you’ll come along with us if you’re interested in learning about the biomedical world of data!

Supporting 100 Data Scientists with a Small Team | Mike Thomson | Data Science Hangout

ADD THE DATA SCIENCE HANGOUT TO YOUR CALENDAR HERE: https://pos.it/dsh - All are welcome! We’d love to see you! We were recently joined by Mike Thomson, Data Science Manager at Flatiron Health, to chat about managing open source tools and maintaining R packages, creating reproducible reports for Word and Excel using Quarto, the “hub and spoke” support model for data scientists, and applying R and Posit tools in Real World Evidence (RWE) oncology space. In this Hangout, we explore creating reproducible outputs using Quarto for formats like Word and Excel. Flatiron Health uses Quarto because it allows the reproducible publication of analyses to multiple formats simultaneously (like HTML and a downloadable Word document) from the same source code. A specific challenge discussed was outputting formatted analytic tables to Excel, as this is not natively supported by Quarto. Erica Yim, from Mike’s team, detailed how they built an internal R function that uses the flexlsx package along with flextable to easily output pre-existing formatted tables from a Quarto document into an Excel template. Resources mentioned in the video and zoom chat: flexlsx R package GitHub repository → https://github.com/pteridin/flexlsx DBPlier PR for Snowflake Translations (contributed to by Flat Iron Health) → https://github.com/tidyverse/dbplyr/pull/860 If you didn’t join live, one great discussion you missed from the zoom chat was about the pain points of exporting data from Quarto to Word or Excel, particularly concerning table formatting and styles. Attendees in the chat strongly highlighted the difficulty of managing table formatting, including issues with table cross-references, headers, and footers. They noted that dealing with styles often requires workarounds, such as creating flextables that match desired Word styles instead of relying on default table styles.

R & Python Interoperability in Data Science Teams | Dave Gruenewald | Data Science Hangout

ADD THE DATA SCIENCE HANGOUT TO YOUR CALENDAR HERE: https://pos.it/dsh - All are welcome! We’d love to see you! We were recently joined by Dave Gruenewald, Senior Director of Data Science at Centene, to chat about polyglot teams, data science best practices, right-sizing development efforts, and process automation. In this Hangout, we explore working in a polyglot team and fostering interoperability (a word that Libby loves, but struggles to pronounce out loud). Dave Gruenewald emphasizes that teams should use the tools they are comfortable with, whether that’s R or Python. Some strategies for collaboration across languages that Dave suggests include tools like Quarto to seamlessly run R and Python code in the same report. Teams utilize data science checkpoints, saving outputs as platform-agnostic file types like Parquet so that they can be accessed by any language. The use of REST APIs allows R processes to be accessed programmatically by Python (and vice versa), which can be a real game-changer. The newly released nanonext package was also highlighted as a promising development for improved interoperability. Resources mentioned in the video and zoom chat: Posit Conf 2025 Table and Plotnine Contests → https://posit.co/blog/announcing-the-2025-table-and-plotnine-contests/ nanonext 1.7.0 Tidyverse Blog Post → https://www.tidyverse.org/blog/2025/09/nanonext-1-7-0/ If you didn’t join live, one great discussion you missed from the zoom chat was about pivoting away from academia, including leaving PhD programs. Many attendees shared their personal experiences of making the difficult decision to drop out of a PhD program. The community suggested alternative terms like “pivot,” “reallocating your resources,” or being a “refugee fleeing academia” instead of “drop out.” Dave Gruenewald shared that he himself left a PhD program but has “no regrets about that.” Did you leave a PhD program?

Theming Made Easy: Introducing brand.yml (Garrick Aden-Buie, Posit) | posit::conf(2025)

Theming Made Easy: Introducing brand.yml Speaker(s): Garrick Aden-Buie Abstract: brand.yml is an exciting new project from Posit that radically simplifies theming. Every data science tool supports some form of theme and appearance customization, but each app framework, output format, or visualization tool requires its own special syntax for theming. The goal of brand.yml is to create a portable and unified interface for brand-related theming that can be used anywhere that data science artifacts are produced.

The Psychology of Technologists (Cat Hicks, Catharsis Consulting) | posit::conf(2025)

The Psychology of Technologists Speaker(s): Cat Hicks Abstract: Technology teams are struggling to be heard. Technologists are grappling with high turnover, high burnout, and low resilience in the face of rapidly-accelerating technological change. Even though effective technical teams are an essential part of our world continuing to work, many organizations struggle to understand their technical teams, stuck in old stereotypes that treat technical people like isolated machines. To build a thriving future, we need a new way of working together and understanding our own minds as we build technology. In my empirical research across thousands of developers, technical managers and their teams, we’ve explored what a psychologically-rich environment looks like for modern technologists and found important signals that can guide teams toward greater resilience, innovation, and thriving. In this keynote we’ll unlock access to the psychological sciences and evidence that you can use to make your every day more human.

Making the most of artificial and human intelligence for data science (Hadley Wickham, Joe Cheng)

Making the most of artificial and human intelligence for data science Speaker(s): Hadley Wickham; Joe Cheng Abstract: This presentation explores the complex and often contradictory nature of large language models (LLMs) in data science, acknowledging the simultaneous excitement and apprehension that we feel toward these technologies. We’ll provide a practical framework to help you understand the LLM ecosystem (from foundation models and hosting to SDKs and applications) that supports our current philosophy: augmenting, not replacing human intelligence. The talk demonstrates how Posit is addressing this space through two complementary approaches: building SDKs and tools that help you create your own LLM-powered solutions, and developing integrated LLM capabilities directly into data science workflows through tools like Positron assistant and databot. We’ll showcase practical, immediately useful applications while addressing current limitations, providing you with both the emotional preparation and technical foundation needed to effectively leverage LLMs in their data science practice today. posit::conf(2025) Subscribe to posit::conf updates: https://posit.co/about/subscription-management/

Observability at scale (Barret Schloerke, Posit) | posit::conf(2025)

Observability at scale: Monitoring Shiny Applications with OpenTelemetry Speaker(s): Barret Schloerke Abstract: Understanding what happens behind the scenes in production Shiny applications has always been challenging. When users experience slow response times or unexpected behavior, developers are left guessing where bottlenecks occur. This talk introduces OpenTelemetry integration for Shiny for R, a new approach to profiling code and understanding application behavior. Through a chat-enabled weather application, we’ll explore how complex user interactions trigger cascading events across multiple processes. You’ll learn how OpenTelemetry’s “high-quality, ubiquitous, and portable telemetry” can provide complete visibility into your Shiny application’s performance with minimal setup… just a few environment variables! After walking through the chat app, you’ll have a taste of how to implement comprehensive monitoring for your Shiny applications in production, enabling you to proactively identify and resolve unexpected performance issues.

Engineer Insightful Shiny Apps with Behavioral Science (Jeremy Winget, CrossStack) | posit::conf

Death by Dropdown? Engineer Insightful Shiny Apps with Behavioral Science Speaker(s): Jeremy Winget, PhD Abstract: Opening a Shiny app to endless dropdowns and scattered filters leads to immediate disengagement and feeling like “death by dropdown”. This talk introduces the Behavioral Insights Design (BID) Framework, a behavioral science roadmap that transforms overwhelming dashboards into guided user journeys. Using the “Interfaces Need A Smart Vision” mnemonic, we’ll explore five stages: Interpret user needs through data storytelling, Notice cognitive friction points, Anticipate user behavior, Structure the application, and Validate & empower users. Drawing from established theories and real-world production examples, attendees will see how applying behavioral science can dramatically reduce the time between “Where do I even start?” and “Aha, now I get it!”. You’ll leave with practical techniques using the new {bidux} package to help transform user confusion into confident exploration and build dashboards that guide users toward better decisions (and fewer ghosted users).

I wrote this talk with an LLM - Hadley Wickham (useR! 2025 Keynote 1)

Presented by: Hadley Wickham (PositPBC) In this keynote, I’ll explore the evolving relationship between data scientists, statisticians, and large language models through a unique experiment: this entire talk was created in collaboration with an LLM. From outline to slides, from code examples to key insights, I’ll share the practical realities of using AI as a thought partner in the R ecosystem. Drawing on my experience developing tidyverse packages and teaching data science, I’ll demonstrate how LLMs can augment (rather than replace) the R user’s workflow. We’ll examine specific examples where AI assistance shines—rapid prototyping, documentation generation, and creative ideation—alongside areas where human expertise remains irreplaceable. Most importantly, I’ll reflect on what this experiment reveals about the future of our community: How might AI change the way we teach R? What new skills should we prioritize? And how can we ensure that the tools we build remain accessible and empowering for all users? Join me for this meta-exploration of AI’s role in our work, with honest reflections on both the promise and limitations of these new collaborators in our statistical computing journey. This abstract was generated by Claude Sonnet 3.7 and lightly edited by me. I used the prompt: I am Hadley Wickham, chief scientist at RStudio/Posit and I’ve been invited to give a keynote on AI at the useR conference. Please write a talk abstract for a talk entitled ‘I wrote this talk with an LLM’

New data science tools & old laptops on fire | Jenny Bryan | Data Science Hangout

ADD THE DATA SCIENCE HANGOUT TO YOUR CALENDAR HERE: https://pos.it/dsh - All are welcome! We’d love to see you! We were joined by Jenny Bryan, Senior Software Engineer at Posit, to chat about (setting laptops on fire,) adapting careers to embrace change and new technologies, behind-the-scenes technical advancements powering the R ecosystem with tools like Positron, demystifying project-based workflows, plus LLM integration and best practices in programming. Listen to this episode to hear us chat about topics like this: the benefits and limitations of using Large Language Models (LLMs) in programming. Jenny shared her initial skepticism towards LLMs for coding in R, but her attitude changed significantly when applying LLMs to problems involving languages she was less familiar with, like Rust or TypeScript. adapting in your career to embrace change and new technologies. Jenny, who describes herself as being on a “third career”, transitioned from management consulting to a statistics professor, and then to a senior software engineer at Posit. She talks a bit about her career journey and how she’s embracing new stuff (ahem, Typescript) so that she gets to keep doing cool stuff! Positron IDE for R package development. She specifically praises Positron’s unique test explorer and reliable console, and its integrated Data Explorer. For many, Positron offers out-of-the-box data science functionality, unlike other IDEs that require extensive customization. what new technologies like Ark, Air, and Positron mean for the longterm health of R. Jenny’s been working on lots of nerdy things behind the scenes at Posit and she talks all about how they’re great for developers, package builders, data scientists, and engineers alike. Another tidbit from this hangout: Jenny gave some advice for those looking to branch into software engineering without formal training: try reading code from admired developers, inviting code reviews, and undertaking small, recreational package development projects to gain practical experience and confidence. She also advocates for adopting a project-oriented workflow (associated with her famous “laptop on fire” remark, of course) using tools like the here package for managing project paths.

Data Science in the Energy Industry | Frank Hull | Data Science Hangout

To join future data science hangouts, add it to your calendar here: https://pos.it/dsh - All are welcome! We’d love to see you! We were recently joined by Frank Hull, Director of Data Science and Analytics at ACES, to chat about forecasting energy demand and prices, managing over a thousand data models, full-stack data science, and advanced machine learning techniques for time series analysis. In this Hangout, we explore the necessity of managing a vast number of data models in the energy industry. Frank’s team at ACES oversees over a thousand models (nearly 2,000, actually!), a staggering number explained by the complexity and fragmentation of the wholesale energy market. The United States is divided into various Independent System Operators (ISOs), each possessing unique regulations and diverse resource mixes. Each of ACES’s 40+ portfolios can operate in different geographical areas within an ISO, presenting distinct challenges that necessitate individual modeling. These models are used to simulate a wide range of time horizons, from the next hour or day-ahead market to long-term financial planning and infrastructure decisions spanning 25 years. This intricate modeling helps in understanding hourly price shapes, demand patterns, supply mixes, and evaluating the effectiveness of new energy generators or hedging strategies, all with the goal of lowering variable costs for cooperatives and mitigating critical risks like blackouts during peak demand.

The Future of Asynchronous Programming in R - Charlie Gao

Asynchronous programming can be a powerful paradigm, whereby computations are allowed to run concurrently without blocking the main session. It is an opportune time to survey the current landscape, as R infrastructure in this respect has matured significantly over recent years. Instead of running a script sequentially from top to bottom, logic that takes a long or unpredictable amount of time to complete may be offloaded to different R processes, possibly on other computers or in the cloud. In the meantime, the main session may be running constantly and non-interactively, performing operations in real time, synchronizing with these tasks only when necessary. This style of programming requires a very specific set of tooling. At the very base, there is an infrastructure layer involving key enabling packages such as later and mirai. It will be explained at a high level why these two packages together currently offer the most complete and efficient implementation of async for the R language. There are further tools which expand async functionality to cover specific needs, such as the watcher package for filesystem monitoring. There are then a range of tools built on top of these, bringing async capabilities to the end-user, such as the httr2 package for querying APIs and the ellmer package for interacting with LLMs. In addition to these existing tools, exciting developments in asynchronous programming are just around the corner. These will be previewed, together with speculation on what might be possible at some point in the future

A first look at Positron - Julia Silge

Description Positron is a next generation data science IDE built by the creators of RStudio. It has been available for beta testing for a number of months, and R users may have wondered if they should try it or if it will be a good fit for them. This new IDE is an extensible tool built to facilitate exploratory data analysis, reproducible authoring, and publishing data artifacts, and it is an IDE that supports but is not built only for R. How should an R user think about Positron, compared to the other options out there? In this talk, learn about how and why Positron is designed the way it is, what will feel familiar or new coming from other IDEs such as RStudio, and when (or if) people who use R should consider giving it a try. You’ll hear about different choices when it comes to defaults and ways of working, such as how to think about your projects or folders and how to manage multiple versions of R. You will also learn about new functionality for R users and package developers that we have never had before, like new approaches for managing R package tests and the ability to customize an IDE using extensions. If you are curious about Positron and how it fits into the R ecosystem, you’ll come away from this talk with more details about its capabilities and more clarity about whether it may be a good choice for you.

Deploying Scikit-learn models for in-database scoring with Snowflake and Posit Team

Modern data science workflows often face a critical challenge: how to efficiently deploy machine learning models where the data lives. Traditional approaches require moving large datasets out of the database for scoring, creating bottlenecks, security concerns, and unnecessary data movement costs. In this demo, Nick Pelikan at Posit highlights how orbital bridges the gap between Python’s rich ML ecosystem and database-native execution by converting scikit-learn pipelines to optimized SQL. This enables data scientists to: Use familiar Python tools for model development Automatically translate complex feature engineering to SQL Deploy models without rewriting code in different languages Maintain model accuracy through faithful SQL translations While this example focuses on Python, Nick also gave this demo using Orbital for R users: https://youtu.be/pnEjYNgOG9c?feature=shared Helpful resources: Follow-along blog post: https://posit.co/blog/snowflake-orbital-scikit-learn-models/ Supported models for Orbital: https://orbital.tidymodels.org/articles/supported-models.html Orbital (Python) GitHub Repo: https://github.com/posit-dev/orbital Orbital (R) GitHub Repo: https://github.com/tidymodels/orbital Databricks and Orbital for R and Python model deployment: https://posit.co/blog/databricks-orbital-r-python-model-deployment/ Emily Riederer’s XGBoost example with Orbital: https://www.emilyriederer.com/post/orbital-xgb/ Sara Altman’s blog post on Shiny + Databases: https://posit.co/blog/shiny-with-databases/ Emil’s introduction of orbital: https://emilhvitfeldt.com/talk/2024-08-13-orbital-positconf/ Nick’s Blog on Running Tidymodel Prediction Workflows with Orbital: https://posit.co/blog/running-tidymodel-prediction-workflows-inside-databases/ If you’d like to learn more about using Posit Team, you can always schedule time to chat with Posit here: https://posit.co/schedule-a-call/

Uniting the pharma industry with data science | Ross Farrugia | Data Science Hangout

To join future data science hangouts, add it to your calendar here: https://pos.it/dsh - All are welcome! We’d love to see you! We were recently joined by Ross Farrugia, Data & Insights Engineering Product Family Lead at Roche/Genentech, to chat about Pharmaverse, open source in pharma, career progression in the industry, and the impacts of AI to the pharma industry. In this Hangout, Ross tells us all about the Pharmaverse, an open-source initiative he co-founded, which aims to unite companies in the pharmaceutical industry. Instead of independently repeating similar work, companies co-develop and share the effort for building, maintaining, and testing code, especially for clinical trials and submissions to regulatory bodies. This collaborative approach, primarily built around R but open to other languages like Python, helps accelerate the delivery of drugs to patients and improves the review and approval process by health authorities. The Pharmaverse fosters a strong community, allowing for shared intellectual property (IP) and increasing trust and sustainability of packages, as demonstrated by the Admiral package with 10 co-development companies. The community, which includes nearly 2,000 people and 400 code contributors, democratically decides on package inclusion, connecting individuals across the industry to supercharge development efforts.

Why regression still matters | Keith McNulty | Data Science Hangout

To join future data science hangouts, add it to your calendar here: https://pos.it/dsh - All are welcome! We’d love to see you! We were recently joined by Keith McNulty, Analytics Leader at McKinsey & Company, to chat about his unique career path into data science, the importance of regression and network analysis, strategies for self-learning and balancing work, and navigating the evolving landscape of AI. In this Hangout, Keith talks about navigating the evolving landscape of AI, including trustworthiness, risks, and its impact on the data science profession. Keith highlights that AI is rapidly changing and discusses the balance between acquiring technical AI development skills and understanding the trustworthiness and inherent risks of large language models. He suggests prioritizing knowledge of AI’s reliability, as these challenges are likely to endure, and recommends identifying trusted sources to sift through the hype. The discussion also covers AI’s capacity to identify complex patterns in large datasets, which can be beyond human capabilities. However, it also acknowledges AI’s tendency to be convincingly incorrect. A significant point raised by Keith is his concern that data scientist could be pushed more towards software engineering, and he asked practitioners to consider if they are still engaging in the “science” aspect of data science.

Four steps for managing data teams | Toby Hall | Data Science Hangout

To join future data science hangouts, add it to your calendar here: https://pos.it/dsh - All are welcome! We’d love to see you! We were recently joined by Toby Hall, Executive Vice President and CIO at Delta Dental of Michigan, to chat about all kinds of things, including: data science team management, AI governance and the ethical use of data in healthcare, insurance data types and use cases, and hiring for traits vs. skills in data science. In this Hangout, among other topics, Toby mentions Delta Dental’s “guilty until proven innocent” approach to AI. This involves a two-stage approval process that critically examines use cases for ethical implications, data handling (ensuring data stays within dedicated tenants and doesn’t train public models), and tool appropriateness. The discussion also touches on the regulatory skepticism towards AI from departments of insurance and the broader environmental considerations of AI use. Toby also gives loads of career advice, but our favorite was his four-step process for managing a data team: Put the right people in the right role Give them the right vision of what you’re trying to accomplish, ensuring it’s clear and everyone is aligned on “what that is and why we’re doing it” Give them the right culture to get it done Get out of their way!

Posit Conf 2025 Keynote Previews | Kieran Healy & Jonathan McPherson | Data Science Hangout

To join future data science hangouts, add it to your calendar here: https://pos.it/dsh - All are welcome! We’d love to see you! Thursdays at 12PM US Eastern We were recently joined by upcoming Posit Conf 2025 keynote speakers Kieran Healy, Professor of Sociology at Duke University, and Jonathan McPherson, Software Architect at Posit PBC, to chat about how and why open-source IDEs like RStudio and Positron get made, how to do data visualization for discovery and explanation, what their keynotes are going to be about, and what’s next for Posit’s IDE development, including AI integration. In this Hangout, Kieran talked about the trustworthy data visualization. He highlighted that while data visualization is a powerful way to condense and present information, often creating compelling and authoritative artifacts, phrases like “visual storytelling” can be problematic if they encourage presenting a predetermined narrative not fully supported by data. He emphasized that the trustworthiness of visualizations does not come solely from the techniques used or the software, but from a “web of social processes and individual commitments” that cannot be easily automated. Jonathan talked about the future of Positron and its relationship with RStudio, addressing whether Positron is intended to replace RStudio. He clarified that the long-term goal for Positron is to make it the best Integrated Development Environment (IDE) for working with data in any language. He explained that Positron is built with an extensibility layer, allowing anyone to write plugins for new languages or capabilities, making it a robust and evolving data science workbench. It does not have all of RStudio’s features and makes different design trade-offs. RStudio, having evolved over decades, is highly optimized for specific R-based workflows and remains the best at what it does for those use cases.

Forecasting AI Demand at Microsoft | Sajay Suresh | Data Science Hangout

To join future data science hangouts, add it to your calendar here: https://pos.it/dsh - All are welcome! We’d love to see you! We were recently joined by Sajay Suresh, Senior Director of Data and Applied Science at Microsoft, to chat about data center supply chain planning, forecasting AI demand, and navigating data science careers. In this Hangout, we explored how the emergence of technologies like LLMs changed projections for data center demand. Sajay discussed how forecasting for something with little historical data, like AI demand, required drawing analogies from the past, such as comparing the training/inferencing model to the iPhone and its App Store. A major complexity in current supply chain planning is the lack of fungibility with modern GPUs requiring specific infrastructure like liquid cooling, meaning data centers designed for GPUs cannot easily be repurposed for traditional compute/storage workloads, increasing investment risk if demand is lower than planned.

Open Source in Pharma | Harvey Lieberman | Data Science Hangout

To join future data science hangouts, add it to your calendar here: https://pos.it/dsh - All are welcome! We’d love to see you! We were recently joined by Harvey Lieberman, Associate Director of Data Science at Novartis, to chat about R/Pharma, automating processes, career advice, and data science in drug discovery vs. development. In this Hangout, Harvey talks about a lot of things, like the power of automating processes. He shares examples of how automating mundane tasks can save significant time and identify errors that humans might miss (we all know human error is a thing!). For instance, he automated the analysis of data from 48 Excel sheets that had previously taken a colleague about three months to process by hand; Harvey completed the automated analysis in one hour over lunch and found copying and pasting errors in the original manual process! Automating processes not only increases efficiency but can also help move people into more data-focused roles. Harvey suggests demonstrating that automation speeds things up and, most importantly, removes errors, which is when people start to pay attention and get interested.

Easier data and asset sharing across projects and teams with {pins} and Databricks

Led by Edgar Ruiz, Software Engineer at Posit PBC April 30th at 11 am ET / 8 am PT Sharing data assets can be challenging for many teams. Some may rely on emailed files to keep analyses up to date, making it difficult to keep current or know what version of the data is used. {pins} improves sharing data and other assets across projects and teams. It enables us to publish, or ‘pin’, to a variety of places, such as Amazon S3, Posit Connect and Dropbox. Given recent customer feedback, the ability to publish, or ‘pin’ to Databricks Volumes has been added to R. The same capability is also currently in the works for the Python version of {pins}.

The epigenomics tech stack | Varun Dwaraka | Data Science Hangout

To join future data science hangouts, add it to your calendar here: https://pos.it/dsh - All are welcome! We’d love to see you! We were recently joined by Varun Dwaraka, Director of Bioinformatics and Principal Investigator at TruDiagnostic, to chat about leveraging DNA methylation and machine learning for determining biological age, the journey from wet lab science to bioinformatics, the tech stack used in epigenomics research, and challenges in handling and analyzing genomic data. In this Hangout, we explore how TruDiagnostic leverages DNA methylation, a biomarker that changes with lifestyle and environment, to develop machine learning models for predicting biological age and other health metrics like smoking impact. These tests aim to provide proactive health insights, allowing individuals to track trends and modulate their biological age through lifestyle changes. But the real draw of this episode of the Hangout is Varun’s willingness to open up and talk about himself and his journey from not-so-great student who wanted to be a musician to finding himself as a PhD student and then joining a start-up (to relax a little, of course!).

Gaining trust & driving change | Victoria L. Prince | Data Science Hangout

To join future data science hangouts, add it to your calendar here: https://pos.it/dsh - All are welcome! We’d love to see you! We were recently joined by Dr. Victoria L. Prince, Senior Manager of Statistics at Takeda Pharmaceuticals, to chat about career paths for statisticians, navigating career transitions, building foundational knowledge, and earning respect and influence in the workplace. In this Hangout, we explore Dr. Prince’s journey transitioning from academia to the pharmaceutical industry. Dr. Victoria L. Prince is a statistician and data scientist with 15 years of experience spanning academia and industry. Don’t miss this hangout if you’re interested in gaining trust and driving change (for example, adopting R or Python) in your org. Dr. Prince discussed her deliberate effort to become an unofficial go-to person for questions about R across different parts of her company. She learned through trial and error that gaining trust involves understanding your strengths and adding value to others’ lives by being generous with your knowledge. She achieved this by volunteering her expertise, not saying no to help requests unless in a complete time crunch, and openly sharing information. She believes that as you share, people share back, which enriches your own knowledge. She also mentioned making herself more visible by organizing and sending invitations to R workshops. Consequently, colleagues would recognize her name and connect it to “R” when they saw it.

Pure math to data science at YouTube | Mrinal Raghupathi | Data Science Hangout

To join future data science hangouts, add it to your calendar here: https://pos.it/dsh - All are welcome! We’d love to see you! We were recently joined by Mrinal Raghupathi, Data Scientist at YouTube, to chat about using data science to understand user behavior, causal inference versus correlation, and experimentation in the tech world, among many other things! In this Hangout, we also explored networking strategies. Mrinal shared his approach to networking, including randomly selecting people from the org chart to have coffee chats with and setting personal goals around networking each year, which let him meet people across the org without selection bias. He emphasized the importance of balancing attending talks at conferences with having hallway conversations and making connections. We here at the Hangout LOVE hallway conversations! Resources mentioned in the video and zoom chat: Trustworthy Online Controlled Experiments → https://www.amazon.com/Trustworthy-Online-Controlled-Experiments-Practical/dp/1108724264 Mrinal’s textbook, “An Introduction to the Theory of Reproducing Kernel Hilbert Spaces” → https://www.amazon.com/Introduction-Reproducing-Cambridge-Advanced-Mathematics/dp/1107104092 Ted’s Guide to Conferences for Introverts → https://laderast.github.io/posts/2018-05-17-a-introvert-s-survival-guide-to-conferences/ If you didn’t join live, one great discussion you missed from the zoom chat was about how many hours a week people get to program in their language of choice. Sixteen people chimed in to share how much they get to code, and answers varied from 0-5 hours per week to 35-40 hours per week, with most people saying they got to spend upwards of 75% of their time coding How much do you get to code every week?! ► Subscribe to Our Channel Here: https://bit.ly/2TzgcOu Follow Us Here: Website: https://www.posit.co Hangout: https://pos.it/dsh LinkedIn: https://www.linkedin.com/company/posit-software Bluesky: https://bsky.app/profile/posit.co Thanks for hanging out with us!

Company-branded reports, apps, and dashboards made easier with brand.yml & Posit

You will learn: How to apply consistent company branding across reports, dashboards, and apps Key Links: GitHub Repo for Example: https://github.com/skaltman/brand-yml-demo brand.yml GitHub repo: https://posit-dev.github.io/brand-yml/ Follow-along blog post: https://posit.co/blog/unified-branding-across-posit-tools-with-brand-yml/ Q&A after the Demo: https://youtube.com/live/kuEbRfmm4G4?feature=share Additional Resources Mentioned in Q&A: Quarto specific page on brand: https://quarto.org/docs/authoring/brand.html Typography: https://posit-dev.github.io/brand-yml/brand/typography.html brand.yml + pkgdown: https://github.com/rstudio/bslib/tree/main/pkgdown LLM brand.yml prompt: https://posit-dev.github.io/brand-yml/articles/llm-brand-yml-prompt/ Inspiration/gallery: https://posit-dev.github.io/brand-yml/inspiration/ Why we think this is important: Consistent company branding in your reports and apps (with your logo, colors, and fonts) can help make your work look more professional, but are often tricky to get right. Common challenges we’ve heard from the community: Excessive manual effort: Applying colors, fonts, and logos across reports, apps, and dashboards takes time and is prone to errors. Difficult to update: When brand guidelines change, it’s difficult to update all products consistently. Team consistency: Ensuring all contributors follow branding guidelines is challenging to manage. How to join future events: We host workflow demos the last Wednesday of every month. You can add them to your calendar with this link: https://www.addevent.com/event/Eg16505674 Full playlist of workflow demo recordings: https://www.youtube.com/playlist?list=PL9HYL-VRX0oRsUB5AgNMQuKuHPpNDLBVt Have suggestions?

DuckDB and the future of databases | Hannes Mühleisen | Data Science Hangout

To join future data science hangouts, add it to your calendar here: https://pos.it/dsh - All are welcome! We’d love to see you! We were recently joined by Hannes Mühleisen, Co-founder and CEO at DuckDB Labs, to chat about the evolution of database systems, the unique architecture of DuckDB, and how to find opportunities in areas others might consider “boring.” He also showed us a picture of the real life duck, Wilbur, that inspired the name DuckDB! 🦆 In this Hangout, we explore how DuckDB is changing the traditional concept of a database by making it accessible to a wide range of users and use cases. We also discuss its origins and how it was inspired by the challenges of data analysis and the importance of focusing on real user problems when building tools. What is a database and where does it live? DuckDB is challenging database assumptions by saying… maybe your expensive laptop can hold a database instead of just pinging one? Maybe it can do more than just run web browsers! Hannes wants you to know that database doesn’t have to be a bad word, and that you can actually have a great experience with one. If the data community’s affinity and enthusiasm for DuckDB is any indication, we think he’s right. We hope you listen in to hear Hannes talk about: a simple explanation of what DuckDB is, DuckDB’s in-process architecture and why it’s so cool, different DuckDB use cases (should you be using DuckDB?), DuckDB’s compatibility with cloud data systems, and more.

Data science and automation in publishing | Sophia Tee | Data Science Hangout

To join future data science hangouts, add it to your calendar here: https://pos.it/dsh - All are welcome! We’d love to see you! We were recently joined by Sophia Tee, Senior Director of Data Science at Penguin Random House, to chat about marketing automation, the use of data science in publishing, and the transition from ID to manager in the realm of data science. In this Hangout, we explore lots of topics, like how Sophia’s team has automated the campaign creation process, reducing a two-week process to 30 minutes, while also improving campaign performance. That’s pretty amazing! Needless to say, we had lots of questions. She also had some great insights to share on the data science skills to strive for in the world of publishing as she experiences it. How organized is your code? It needs to be well-organized so that it “can be shared and understood by a lot of different people.” She recognizes that not all data scientists have experience productionizing models, but that it’s important in her line of work to be a full stack data scientist. Communication is paramount. Sophia says, “at the end of the day it doesn’t matter how great your model is if you can’t explain it. It’s really hard to sell it. So, I think being able to speak in plain English about what you did, and what the outcome is, and what you expect people to do about it is really important.” She stresses the importance of understanding the underlying data and the business context, too. Remember who you are speaking to and how your results relate to their KPIs. You’ll have to listen in to hear more!

Sharpening your axe and the BAU trap | Steph Locke | Data Science Hangout

To join future data science hangouts, add it to your calendar here: https://pos.it/dsh - All are welcome! We’d love to see you! We were recently joined by Steph Locke, Digital and App Innovation Leader at Microsoft, to chat about how to persuade your manager to give you more time for professional development, why “business as usual” (BAU) work can choke development, and how killing projects is actually a good thing. In this Hangout, we explore the importance of investing time in skill development and how this can lead to long-term gains in efficiency and quality. Steph shares advice on how to talk to managers about the value of “sharpening your axe,” and why it is more efficient to train in order to do things well initially than to spend time on continuous maintenance of subpar work. Is a bunch of “business as usual” work bogging down the potential output of development teams? This is where Steph’s concept of investing in high quality work up-front comes in. She talks about the dangers of rushing to release products that aren’t built with high quality and low ongoing maintenance in mind: “…when [people] don’t necessarily have time to invest in doing things in a way that’s going to have high quality and low maintainability requirements and is easy to extend and create new things, when people aren’t doing that, anything they ship is going to then cost them more time to do something to to look after whatever they’ve shipped. That then gives them less time to ship the next thing.” If this resonates with you, give Steph a follow on LinkedIn and make sure you read her article.

Navigating technology for data teams | Stanislav Seltser | Data Science Hangout

To join future data science hangouts, add it to your calendar here: https://pos.it/dsh - All are welcome! We’d love to see you! We were recently joined by Stanislav Seltser, VP of Enterprise Architecture and AI Infrastructure at State Street Global Advisors, to chat about how to strategically approach the business leadership about investing in new tools, forecasting technology obsolescence for data work, and fostering innovation and creativity in data science teams. In this Hangout, we explore the factors that can help forecast when a technology will become obsolete, including the rate of commits to open-source projects and the frequency of vendor releases. Stanislav also shares his approach to evaluating technology based on usability, cost, and maintainability, as well as how to ensure that chosen technologies provide a return on investment. Stanislav recommends treating the need for a new tool the way you would if you were pitching a start-up, with a business plan and a technical prototype, to really show your understanding of what you’re asking for. Stan also shared some solid career advice, so stick around for that. No surprise here, his advice starts with community - being social and connecting with as many people as you can - but he really emphasizes mentoring and helping others succeed. We agree, Stan!

From paramedic to leading analytics in pharma | Dan Haight | Data Science Hangout

To join future data science hangouts, add it to your calendar here: https://pos.it/dsh - All are welcome! We’d love to see you! We were recently joined by Dan Haight, Director of Continuous Improvement Analytics at Merck, to talk about his unconventional career path, the value of lateral career moves (check out his book recommendation on this!), and the importance of creating “great charters” for successful stakeholder communication in projects. Dan’s advice about project management in this episode is so valuable. He recognizes how tempting it is to rush into a project without knowing all the facts beforehand, but then your scope starts to balloon, you see the project getting behind, and there are all these constraints you weren’t aware of. So, he says to take time to build a charter, be upfront with stakeholders about realistic timelines, and then use the charter as a contract to negotiate scope changes and resource allocation. He also discusses the challenges of working with incomplete data and the need to triangulate information from multiple sources to ensure accuracy and build confidence in the findings. If you’re a job seeker or looking to transition, Dan came with great advice to pursue continuous learning, network, and hone the ability to effectively communicate the value of their work. You’ll have to listen to learn more! If you didn’t attend live, you missed the party in the zoom chat People were excited about posit::conf 2025 early bird tickets getting released, and there was a SUPER great discussion about how to share your work when it’s all under NDA or very private due to security reasons. There was some great suggestions, like: 🥸 Anonymize data if it’s possible, or present a similar project abstractly Use public data to demonstrate the methods you used, even if you can’t showcase the findings Emphasize lessons learned during a project (ah-hah moments) instead of the business impacts IF the overall project failed or wasn’t implemented (as is the fate of many DS projects!) Document projects as you go, in a format that you can safely take with you, so that you can remember all these things even after you leave your role Lean on your friends and colleagues to help you describe the impacts you had on a project, or the importance of what you did (we all need to be hyped up sometimes when it comes to writing resumes!!)

Data for good, mentoring, and stellar internships | Sebastien Ouellet | Data Science Hangout

To join future data science hangouts, add it to your calendar here: https://pos.it/dsh - All are welcome! We’d love to see you! We were recently joined by Sebastian Ouellet, Senior Staff Developer at Kinaxis, to chat about volunteering with data-for-good initiatives, his career path in data science, and developer/intern mentorship. We talked all about the value of mentorship for both the mentor and mentee, and how Kinaxis’s internship program allows interns to innovate and grow by owning brand new projects. Sebastien emphasized the positive reciprocal nature of mentorship, with advantages for both sides: mentees and interns gain invaluable knowledge, guidance, and support from experienced professionals, and regular communication enables interns to receive timely feedback, ask clarifying questions, and course-correct their approach when necessary; for mentors, the act of teaching and explaining concepts to someone new really forces them to re-examine their understanding of familiar processes, which can help identify gaps in documentation or reveal areas for improvement in existing systems. Sebastien also covered the strategic benefits of allowing interns to spearhead new and innovative (instead of existing) projects. Basically, allowing interns to own projects, coupled with a supportive mentorship structure, creates a win-win scenario with tangible benefits for both the interns and the company: Innovation: By entrusting interns with fresh projects, they foster an environment of innovation. Interns bring a new perspective, allowing them to challenge the status quo and come up with novel solutions. Knowledge Management: Interns build valuable resources, including documentation, code repositories, and presentations, as they progress through their projects. These resources create a knowledge base that can be leveraged by other team members, even after the intern leaves the team or the company. Project Pipeline: the company gets to use these intern-driven projects as a proving ground for new ideas. Successful projects can evolve into production-ready solutions (and have already)! If you didn’t attend live, you missed some GREAT conversations in the zoom chat, including one in which we all admitted to the many times we’ve reinvented the wheel before talking to people about what we were trying to do and having them tell us there was an easier way.

pandas vs Polars DataFrames? 👨🏻‍🍳 #python

Here’s Marco Gorelli’s take on why lazy execution matters So with pandas, everything happens eagerly. You give the library some instructions, and it evaluates your instructions the moment you give them. With Polars, there’s an option to give it some instructions, it can wait a bit, and then do them all together in the most optimal way that it can detect. If I was to tell you to cook me a recipe ‍ …and I gave you the steps one at a time …and for each step, you have to go out and buy the ingredients that you need for that step ^ This is going to be a pretty inefficient way of making a cake But if I can give you the recipe beforehand: …you can buy all the ingredients together …you can maybe do 2 steps at the same time ^ This is going to be a much nicer cooking experience #positshorts

Zac Davies - Elevating enterprise data through open source LLMs

In an era where data privacy and security are paramount, many organizations are keen on leveraging Large Language Models (LLMs) in conjunction with their proprietary data without exposing it to third-party services. Recognizing this need, our talk, “Elevating Enterprise Data Through Open Source LLMs,” showcases an approach that integrates the capabilities of Databricks and Posit, enabling businesses to maintain ownership and control over their data and LLMs while delivering value to their customers. The core of our discussion revolves around a system architecture that synergizes the strengths of Databricks and Posit technologies, providing a comprehensive solution for enterprise data and open-source LLMs. Databricks is responsible for data management and processing, offering a seamless environment for hosting, serving, and fine-tuning open-source LLMs. Keeping data and models in the secure perimeter of Databricks lowers the risk of data exfiltration tremendously, and also benefits from the scalable data processing and machine learning capabilities - including the recent acquisition MosaicML - that Databricks delivers. Posit steps in to streamline the process through Posit Workbench, the developer platform for data science with custom integrations for working with Databricks. This allows developers to write, test, and refine their code in a familiar and powerful setting while still being able to access the data, compute, and model serving offered by Databricks. In addition, Posit Connect offers an easy-to-use platform for deploying these applications, ensuring that the end-to-end process, from development to deployment, is efficient, secure, and aligned with enterprise standards. Attendees of this talk will gain valuable insights into constructing and deploying LLM-powered applications using their enterprise data. By the end of the session, you will have a clear understanding of how to leverage Databricks for optimal data management and LLM operations, alongside Posit’s streamlined development and deployment processes. This knowledge will empower you to deliver secure, effective, and scalable LLM-powered applications, driving innovation and value from your enterprise data while upholding the highest standards of data privacy and security.

Mark Wang - Using GitHub Copilot in R Shiny Development

Generative AI tools, like the GitHub Copilot, are revolutionizing software development, by automating routine tasks and boosting programmers’ productivity. R Shiny development is uniquely positioned to benefit from GitHub Copilot. Copilot can accelerate the process by automating front-end tasks, especially those involving HTML and JavaScript, as well as testing and documentation, thus letting R Shiny developers focus more on the value-added aspects of data science and statistics. The basic workflow of using GitHub copilot in R Shiny development has three parts: prompt, context, and iteration. Three types of prompts: command, question, and lead-in, all have strong use cases in R development. Specific prompts create more helpful results as compared to vague ones, and Copilot can help add more specificity to your prompts when you are not familiar with the domain topic. The most important source of context for Copilot is typically your codebase, which should be well-organized and open in your IDE. Additionally, knowledge on the internet, as well as simple and concrete examples, can also be valuable contexts. However, sensitive personal information in your context can stop Copilot from generating appropriate responses. Iteration is modifying and enriching your prompt and context to improve the quality of Copilot’s responses. Function and module documentation is a valuable step of iteration. As R Shiny is often used with fast-hanging data, Copilot serves as a powerful tool in the iteration from static to dynamic app testing in the shinytest2 framework. As we iterate over our prompt and context to generate better responses from Copilot, it is worthwhile to build an internal knowledge base in the form of prompt dictionaries. A Copilot knowledge base can include information specific to your organization that can be reused across projects, such as security and compliance conventions, code and documentation standards, and employment process and environment.

The importance of relevant analytics | Nechama Katan @ Pfizer | Data Science Hangout

We were recently joined by Nechama Katan, Director of Innovative Data Analytics at Pfizer, for a conversation about relevant analytics, the importance of understanding business context, and strategies for bridging silos within organizations. “Technology on its own doesn’t do you any good.” Nechama highlighted the common pitfall of organizations prioritizing technology over business needs. She stressed that technology is only valuable when it directly addresses a business problem. Often, companies invest in complex data infrastructure and tools without a clear understanding of how they will be used to answer critical business questions. This can lead to frustration and a lack of adoption by business users. Nechama encouraged data professionals to prioritize understanding the business context behind the data. By asking questions, collaborating with colleagues in other departments, and actively seeking to understand the challenges and goals of the business, data scientists can ensure their work delivers tangible value. How would you recommend acquiring the business background needed to succeed? In our Hangout chat, Nechama stressed the importance of building relationships and breaking down silos within organizations. She encouraged data professionals to: ● Be curious: Ask questions relentlessly, seeking to understand the perspectives and challenges of colleagues in other departments. ● Offer help: Identify areas where your expertise can be valuable to others and proactively offer assistance. ● Be kind: Approach interactions with empathy and a genuine desire to build connections. In sharing her career advice, Nechama advocated for “managing down,” prioritizing collaboration and support for peers. Building strong relationships and fostering a culture of teamwork is essential for solving problems and achieving impactful outcomes Resources from the Chat: Mosaic Crochet Shiny App Cascades: How to Create a Movement that Drives Transformational Change by Greg Satell Launching DyslexicU, the World’s First University of Dyslexic Thinking Move Fast and Break Shit: Burning Man’s Lessons for Success in Work and Life by Heather White One Data Scientist’s Assimilation of the Product Lexicon Spurious Correlations There’s Only One R in Pfizer ► Subscribe to Our Channel Here: https://bit.ly/2TzgcOu Follow Us Here: Website: https://www.posit.co LinkedIn: https://www.linkedin.com/company/posit-software Twitter: https://twitter.com/posit_pbc To join future data science hangouts, add to your calendar here: pos.it/dsh (All are welcome!

Data-level permissions using Posit Connect (with Databricks, Snowflake, OAuth)

Should one viewer of your app be able to see more (or different) data than another? Maybe colleagues in California should only see data relevant to them? Or managers should only have access to their own employee data? The Connect team joined us for a demo on inheriting data-level permissions using Posit Connect and Databricks Unity Catalog. While this workflow uses Databricks to illustrate federated data access controls, this same methodology can also be applied to Snowflake or any external data source that supports OAuth. During this workflow demo, you will learn: How to define row-level access controls in Databricks Unity Catalog How to create a Databricks OAuth integration in Posit Connect How to write interactive applications that utilize the viewer’s Databricks credentials when reading data from Databricks Unity Catalog, providing the viewer with a personalized experience depending on their level of data access How to deploy this application to Posit Connect and share it within your organization If you’d like to talk further with our team 1:1 about doing this, you can find a time to chat here: https://posit.co/schedule-a-call/?booking_calendar__c=WorkflowDemo Ps. To enable OAuth integrations, your team will need to upgrade to Posit Connect 2024.08.0. This feature is available in Enhanced and Advanced product tiers.

Creating tests for Shiny for Python apps | Karan Gathani | Posit

With the Shiny for Python v1.0 release, Shiny provides a simple way to create a test file for your Shiny app. The shiny add test command is a helpful CLI tool for Shiny app developers. It simplifies the process of creating test files for their applications. When you run this command, it prompts you to input two pieces of information: the path to your Shiny app file and the desired location for the new test file. Once you provide these details, the command automatically generates a test file at the specified location. This new file includes a pre-made test template, giving you a solid starting point for writing your app’s tests.

6 core ideas for public speaking | Blythe Coons & Acacia Duncan @ Articulation | DS Hangout

A must-see episode of the Hangout, especially if you have ever needed to give a presentation (and who hasn’t??). Acacia and Blythe from Articulation are experts at helping presenters craft their messages, and they’ve worked with many, many Posit Conference speakers over the years. If you’ve ever heard conf speakers gush about getting to work with Articulation to prepare their talks, you’ll understand why by the end of this discussion. There’s a reason more than 200 hangout members attended this one! Timestamps: 07:15 What are threshold concepts? What does Articulation do? 09:25 Threshold concept 1 - Speaking is habitual (not natural) 10:15 Threshold concept 2 - Speaking is embodied 11:30 Threshold concept 3 - Speaking is social 12:50 Threshold concept 4 - Speaking is messy 13:45 Threshold concept 5 - Speaking contains multiple genres 15:25 Threshold concept 6 - Speaking requires feedback 17:15 How do you construct a story when presenting data? What resources are there? 19:40 How do you structure a story? 21:05 Why is the Hero’s Journey the wrong structure for storytelling with data? (Your audience is Luke Skywalker, not you!) 24:25 Where do data people go wrong? How can data communicators improve? 25:40 How much information should you include in a presentation? How much is too much? 29:00 Should you create a document to hand out alongside your slides? 32:10 How do you change a company culture of having wordy PowerPoint slides? 34:35 What happens when PowerPoint slides are too wordy? 36:10 How do you reduce stress responses when giving a presentation? 43:15 How can you slow down if you’re a fast talker or nervously speed up while presenting? 46:20 What are some tools for planning presentations? 48:20 How does presenting on Zoom differ from presenting in person? 52:50 Tips for switching back and forth between in person and Zoom 55:00 How do you coach someone on a technical presentation if you’re not an expert in it? 57:45 How can you be yourself when giving a presentation? Here are a few of the key topics covered in the discussion: The threshold Concepts of speaking. These are the core ideas you must understand in order to really succeed in public speaking. Data Storytelling. Spoiler! There is more than one type of story in your data presentation, and you’re not the hero of any of them. Structuring a story. The basics of structure, but also how to answer the right question (spoiler again, it’s not the question you’re interested in). Common struggles in data communication. Do you bury the lede? Are you a non-linear thinker? Do you get super anxious and lost? Do you talk way too fast??? Coping with Zoom. Why presenting on zoom can be a challenge and what we can we do about it.

Reproducible data science with webR and Shinylive | George Stagg | Posit

A fundamental principle of the scientific method is peer review and independent verification of results. Good science depends on transparency and reproducibility. However, in a recent study a substantial 74% of research code failed to run without errors, often caused by diverse computing environments. This talk will discuss the principles of numerical reproducibility in research and show how software can be pinned to specific versions and self-contained as a universal binary package using WebAssembly. This ensures seamless reproducibility on any machine equipped with a modern web browser and, using tools such as Shinylive, could provide a new way for researchers to share results with the community. webR demo website: https://webr.r-wasm.org/v0.3.2/ Shinylive examples: https://shinylive.io/r/ https://shinylive.io/py/ Documentation: https://docs.r-wasm.org/webr/v0.3.2/ https://github.com/posit-dev/shinylive https://github.com/quarto-ext/shinylive

Simon Couch: Fair machine learning

Simon Couch Fair machine learning Cascadia R Conf 2024 Regular talk, 10:25-10:40 In recent years, high-profile analyses have called attention to many contexts where the use of machine learning deepened inequities in our communities. A machine learning model resulted in wealthy homeowners being taxed at a significantly lower rate than poorer homeowners; a model used in criminal sentencing disproportionately predicted black defendants would commit a crime in the future compared to white defendants; a recruiting and hiring model penalized feminine-coded words—like the names of historically women’s colleges—when evaluating résumés. In late 2022, a group of Posit employees across teams, roles, and technical backgrounds formed a reading group to engage with literature on machine learning fairness, a research field that aims to define what it means for a statistical model to act unfairly and take measures to address that unfairness. We then designed functionality and resources to help data scientists measure and critique the ways in which the machine learning models they’ve built might disparately impact people affected by that model. This talk will introduce the research field of machine learning fairness and demonstrate a fairness-oriented analysis of a model with tidymodels, a framework for machine learning in R. Pronouns: he/him Chicago, IL Simon Couch is a software engineer at Posit PBC (formerly RStudio) where he works on open source statistical software. With an academic background in statistics and sociology, Simon believes that principled tooling has a profound impact on our ability to think rigorously about data.

Great Tables: Make beautiful, publication quality tables in Python | Rich Iannone & Michael Chow

Tables are undeniably useful for data work. We have many great DataFrame libraries available in Python, and they give us flexibility in terms of manipulating data at will, but what happens when presenting tables to others? It’s nice to display tables. Tables can efficiently carry information, just like plots do, and at times it is the better way of presenting data. Indeed, it is time to bridge the divide between raw DataFrame output and wondrously structured tables suitable for publication. Now, let us turn our attention to the state of ‘display tables’ in 2024. Let us go over what comprises key components for building effective information displays in tables. It may surprise one how new a well-crafted table can be hewn. We’ll take a look at the combinations of Python packages that fit together to make this important task possible, and marvel together at the tabular results they can provide!

Hadley Wickham - R in Production

R in Production by Hadley Wickham Visit https://rstats.ai for information on upcoming conferences. Abstract: In this talk, we delve into the strategic deployment of R in production environments, guided by three core principles to elevate your work from individual exploration to scalable, collaborative data science. The essence of putting R into production lies not just in executing code but in crafting solutions that are robust, repeatable, and collaborative, guided by three key principles: Not just once: Successful data science projects are not a one-off, but will be run repeatedly for months or years. I’ll discuss some of the challenges for creating R scripts and applications that run repeatedly, handle new data seamlessly, and adapt to evolving analytical requirements without constant manual intervention. This principle ensures your analyses are enduring assets not throw away toys. Not just my computer: the transition from development on your laptop (usually windows or mac) to a production environment (usually linux) introduces a number of challenges. Here, I’ll discuss some strategies for making R code portable, how you can minimise pain when something inevitably goes wrong, and few unresolved auth challenges that we’re currently working on. Not just me: R is not just a tool for individual analysts but a platform for collaboration. I’ll cover some of the best practices for writing readable, understandable code, and how you might go about sharing that code with your colleagues. This principle underscores the importance of building R projects that are accessible, editable, and usable by others, fostering a culture of collaboration and knowledge sharing. By adhering to these principles, we pave the way for R to be a powerful tool not just for individual analyses but as a cornerstone of enterprise-level data science solutions. Join me to explore how to harness the full potential of R in production, creating workflows that are robust, portable, and collaborative. Bio: Hadley is Chief Scientist at Posit PBC, winner of the 2019 COPSS award, and a member of the R Foundation. He builds tools (both computational and cognitive) to make data science easier, faster, and more fun.

{shinylive}: Serverless Shiny Apps | Barret Schloerke | Posit

In the rapidly evolving landscape of web technologies, the integration of R (and Python) with modern web frameworks has become increasingly important for data scientists and developers. This presentation introduces {shinylive}, a new R package that exports Shiny applications to be run within statically hosted websites. We will explore the capabilities of {shinylive} through its use of the innovative R package {webR}, which allows for the execution of R code in the browser (via WebAssembly and service workers) without the need for a centralized server. The presentation will cover the technical foundation of {shinylive}, including its architecture and the integration process with Quarto documents. We will also discuss the practical aspects and drawbacks of exporting Shiny apps with {shinylive}, highlighting the ease of exporting apps to a folder for local use or hosting them on GitHub pages. {shinylive} bridges the gap between Shiny and static websites, making it a valuable resource for interactive data analysis and presentation.

How to inspire people to make a change ✨

Key takeaways from our conversation on the path to effective data stewardship: Change management is hard. To inspire people to change, make it as easy as possible for them to see the path to get there by creating tools to make new tasks easy to complete. A problem not only has to exist, but that problem needs to be recognized to exist. In the data governance space, legal regulations can help push us forward because they create urgency. Data stewardship and data governance enable innovation. You see more of what’s possible when you know what data exists. Core systems form the foundation that enables cutting-edge work like AI development. People have good intentions and want to get their work done and impact the organization. Don’t create processes where the only way to get your job done is to break the process. In the act of governing, remember why you started pulling data together in the first place. Community engagement is incredibly powerful and hearing different perspectives is how we grow. We all face similar problems regardless of our role or industry. An internal community for cross-organizational collaboration is vital for knowing what other people are working on and collaborating. This not only helps you with your data, but also with your career. Implementing effective data stewardship is a journey with companies at all different stages. Those further along the journey may have teams and infrastructure dedicated to this, along with executive buy-in. Others are working to make it happen at the individual level – where it often starts with writing down the definitions of your data (who created it, when it was sourced, intended use, etc.) and recognizing that someone else will use your data output, potentially not in the way you initially intended. #positshorts

From Chaos to Clarity: Implementing Effective Data Stewardship

As a data scientist or data leader, data is at the center of your work. However, management of that data can feel overlooked. Many of us have asked questions like: 🤔 How do we ensure data we create is easily discoverable and reusable? 🤔 What happens when multiple people make different data transformations for similar work? The focused effort of making data accessible and secure has been called many different names: data stewardship, data enablement, data governance, etc. While it’s needed across all levels and departments within an organization, best practices for managing data remain difficult to define. We got together as a community to discuss the importance of driving data stewardship at the individual level. Jamie Warner, Managing Director, Data Science & Pricing at Plymouth Rock Assurance and Dan Boisvert, Head of Data Stewardship at Biogen kicked off the conversation by drawing from their own experiences. Resources mentioned: Follow-up Q&A Blog Post - https://posit.co/blog/the-path-to-effective-data-stewardship/ posit::conf(2024): https://posit.co/conference/ O’Reilly chapter on Data Governance over a Data Life Cycle: https://www.oreilly.com/library/view/data-governance-the/9781492063483/ch04.html Switch by Chip and Dan Heath: https://heathbrothers.com/books/switch/ To engage further with Posit on this topic: Every Thursday at 12 ET we get together for the Data Science Hangout. While there’s no set agenda for the conversation, we often talk about data science leadership, data management best practices, speaking with executives, career advice, and more. Many Posit customers also use an enterprise platform for data governance like Databricks and Snowflake to help people discover, access, and work with the right data securely and efficiently.

Joe Cheng | Managing long-running operations in Shiny | Posit

It’s been years since Shiny evolved to allow asynchronous operations within applications, improving scalability. The introduction of the {promises} package enabled concurrent processing between multiple Shiny sessions, a significant step forward in handling background tasks. However, this did not address the need for intra-session concurrency, where users expect to interact with the application while long-running calculations are executed in the background. Recently, we added a new ExtendedTask feature to Shiny to allow for such intra-session concurrency. This new feature provides a different approach for developers to incorporate asynchronous tasks, enabling smoother user interactions during intensive computations. Alongside ExtendedTask, this talk will also discuss newer methods for launching asynchronous tasks, besides the usual {future} package. The focus will be on the practical application and integration of these features into Shiny applications.

MLOps for a billion pizzas a year | Zack Fragoso @ Domino’s Pizza | Data Science Hangout

We were joined by Zack Fragoso, Head of MLOPs at Domino’s Pizza to chat about his mission to Sell More Pizza and Have More Fun by making the business smarter with data. Speaker bio: Zack Fragoso is the Head of MLOPs at Domino’s Pizza, where he is on a mission to Sell More Pizza and Have More Fun by making our business smarter with data. His team develops ML/AI applications that supercharge the global pizza delivery leader’s e-commerce and in-store platforms. We’ve been able to help reward customers for ordering pizza, give them a better estimate of when their order will be ready, route orders more efficiently, and those are just a few examples! Zack is passionate about MLOPs tools that increase productivity, enhancing cross-team collaboration, and support our model life cycle management. At 11:07 we discussed two key challenges regarding MLOps: scalability and process Scalability Zack explains that while data scientists can develop accurate models on their laptops, scaling those models to handle the immense volume of Domino’s business is a significant hurdle. He emphasizes that Domino’s sells close to a billion pizzas annually, with a high concentration of orders between 5 pm and 8 pm. Events like the Super Bowl push the system even further, requiring the ability to process around 6,000 orders per minute. For Domino’s, this means that models must be not only accurate but also highly performant to handle these spikes in demand. Process The second challenge Zack identifies is related to integrating the experimental nature of data science work with a robust and reliable production process. He acknowledges that data scientists are inherently driven to experiment with data and various modeling techniques. However, translating these experimental models into a production environment requires a more structured approach that encompasses control mechanisms, versioning, and a focus on reliability. Finding the right balance between this need for flexibility in experimentation and the demands of a structured production process is an ongoing challenge for Domino’s.

Michael Derstine @ Wells Fargo | Data Science Hangout

We were recently joined by Michael Derstine, Vice President at Wells Fargo & Company to chat about an opinionated approach to modeling and analytics in mortgage banking. Speaker bio: Michael Derstine leads a team of analysts dedicated to the management of an asset class called Mortgage Servicing Rights (MSR). He is approaching his tenth year in mortgage finance, and has held many roles. He started as a junior analyst, compiling webs of spreadsheet reports in the early hours of the morning before the Traders started their day. Like many in this community, he was driven to make processes better (and make life easier). How do you advocate for a better way? 04:05 - Michael shared his story about waking up before 5 am as a junior financial analyst, pulling together dozens of spreadsheets with hundreds of tabs, other people’s models and recycled work Each day, he’d make sure nothing was wrong before traders started acting on these models. He was motivated to not only make his life easier, but make processes better and remove the operational risk. The spreadsheet process has since moved to data science. It’s completely automated. No junior analyst has to get up at 4:30 am. Those roles still exist but now they’re encouraging them to use languages like R and Python. Michael shared, “I’m very proud of that, but it was a lot of work technically and maybe even more work politically to get that through” If you’re changing the status quo, build a challenger processes by: Building something in parallel Running it side by side and obliterating the old competition to show how much better it is Telling the story to your bosses ► Subscribe to Our Channel Here: https://bit.ly/2TzgcOu Follow Us Here: Website: https://www.posit.co LinkedIn: https://www.linkedin.com/company/posit-software To join future data science hangouts, add to your calendar here: https://pos.it/dsh (All are welcome!

Adam Austin @ The Hartford | Data Science Hangout

We were recently joined by Adam Austin, Director of Data Science at The Hartford to chat more about data science as a tool, but relationships as the real driver of business value and success. Speaker bio: Adam Austin is a data science leader who, over a 10-year career, has been intensely curious about why data science projects fail despite their initial potential. Invariably he has seen that it is not sophisticated models and ideas, but relationships that enable the promise of data and analytics. In addition to advocating for good workflows and development practices, Adam has turned his attention to how data scientists can become better communicators, help business partners articulate their needs, and build bridges to success amidst complex and ambiguous business backdrops – all while having a little fun. After all, maybe the real data science is the friends we make along the way. Here are a few key takeaways from this sessions: ⭐️ Data science thrives on strong relationships. The most challenging aspects of the job often involve navigating business relationships and comprehending how data science fits into a company’s broader goals. ⭐️ When presenting ideas to executives, strive for simplicity and clarity. A straightforward visual representation of data can be more impactful than a complex, difficult-to-explain model. ⭐️ Data science initiatives often involve navigating the complexities of human motivations and organizational politics. ⭐️ Data science teams should aim to be value creators, not just ticket-takers. Transitioning from a reactive to a proactive team requires strategic planning and stakeholder engagement. ⭐️ A robust intake process is essential for vetting and prioritizing data science projects. ⭐️ Data scientists can add significant value by challenging existing metrics and proposing alternative measurement strategies. ⭐️ Growing disconnect between skills emphasized in academic data science programs and the practical needs of the industry. Universities need to equip graduates with the skills to handle real-world data challenges, including data cleaning, wrangling, and understanding business context.

Estimating & communicating ROI for data science projects

A recurring topic in Data Science Hangouts, meetups, and 1:1 chats is the ability to estimate, measure, and communicate the Return on Investment (ROI) for data science projects to business stakeholders. A specific question was: “Are you ever asked to estimate the ROI from an analytics project before the business is willing to invest in anything?" I asked the community if anyone had something to share on this topic, and they delivered! A special thank you to Derek Beaton, Director of Advanced Analytics at St. Michael’s Hospital and Joe Powers, Principal Data Scientist at Intuit who kicked off the group conversation last month by sharing their own experiences. Tips for communicating the ROI for data science projects: Engage stakeholders & identify gatekeepers Align evaluation metrics to stakeholder objectives Establish clear success criteria Anticipate where things can go awry Consistently communicate your central message Prioritize what’s most impactful Promote transparency while measuring project performance Ensure the benefit is unquestionably worth the time investment Additional ROI Resources Mentioned: Analytics Power Hour Podcast - Estimating the Effort for Analytics Projects: https://analyticshour.io/2023/10/31/231-estimating-the-effort-for-analytics-projects/ CDO Matters Podcast with Malcom Hawker: https://open.spotify.com/show/2OJXB8v32CrKbbsv9Uq2vn How to Measure Anything by Douglas Hubbard: https://hubbardresearch.com/7-simple-principles-for-measuring-anything/ If you want to continue conversations like this, we invite you to also join us at the Data Science Hangout every Thursday from 12-1 ET.

You Can Lead a Horse to Water…Changing the Data Science Culture for Veterinary Scientists

Presented by Jill MacKay A retrospective look at supporting data science skills in a research-focussed veterinary school This is a talk about environment management, but not in the way you’re thinking. In many industries, domain-specific experts need enough understanding of data science to support their work and communicate with data scientists, but often have insufficient training in these skills, and limited time with which to obtain data science skills and practice them. This is particularly challenging for those who are interdisciplinary and have limited control over their workload, such as medics and field scientists. In this talk, an educational scientist describes the previous 10 years of supporting veterinary scientists to adopt open science practices surrounding data science. What worked, what failed miserably, and reflections on why it can be so hard to get a horse to drink.

Why You Should Add Logging To Your Code (and make it more helpful) - posit::conf(2023)

Presented by Daren Eiri Learn how the log4r package can help you better understand the errors your code may produce, and how to also get promptly alerted for severe errors by leveraging cloud monitoring solutions like Azure Monitor or AWS CloudWatch When an error happens in your API, Shiny App, or quarto document, it is not always clear what line of code you need to look at, and the error messages aren’t always helpful. By walking through a simple API example, I show how you can use logging packages like log4r to provide error messages that make sense to you. I also show how you can use cloud-based data collection platforms like Azure Monitor or AWS CloudWatch to set up alerts, so you can get notified by email or text message for those severe errors that you need to be immediately aware of. Gain more visibility into the health of your code by incorporating logging and pushing your logs to the cloud.

What an Early 2000s Reality Show Taught Me about File Management - posit::conf(2023)

Presented by Reiko Okamoto Clutter, whether it’s physical or digital, destroys our ability to focus; home organization ideas can be extended to create an workspace where analysts feel inspired to work with data. Ideas from home organization shows are surprisingly applicable to file management. Using a room divider to establish dedicated zones for different activities in a studio apartment is analogous to creating self-contained projects in RStudio. Likewise, swapping mismatched hangers with matching ones to tidy a closet resembles the adoption of a file naming convention to make a directory easier to navigate. In this talk, I will share good practices in file management through the lens of home organization. We all know that clutter, whether it is in our physical space or on our machine, destroys our ability to focus. These practices will help R users of all levels create a serene, relaxing environment where they feel inspired to work with data. https://reikookamoto.github.io/; https://github.com/reikookamoto/posit-conf-2023-neat Presented at Posit Conference, between Sept 19-20 2023, Learn more at posit.co/conference.# Talk Track: Getting %$!@ done: productive workflows for data science.

We Converted our Documentation to Quarto - posit::conf(2023)

Presented by Melissa Van Bussel Elevate your Quarto projects to new heights with these practical tips and tricks! “Wiki”, “User Guide”, “Handbook” – whatever you call yours, we converted ours to Quarto! A year ago, my team’s documentation, which had been created using Microsoft Word, was large and lacked version control. Scrolling through the document was slow, and, due to confidentiality reasons, only one person could edit it at a time, which was a significant challenge for our team of multiple developers. After realizing we needed a more flexible solution, we successfully converted our documentation to Quarto. In this talk, I’ll discuss our journey converting to Quarto, the challenges we faced along the way, and tips and tricks for anyone else who might be looking to adopt Quarto too.

Visualizing Data Analysis Pipelines with Pandas Tutor and Tidy Data Tutor - posit::conf(2023)

Presented by Sean Kross The data frame is a fundamental data structure for data scientists using Python and R. Pandas and the tidyverse are designed to center building pipelines for the transformation of data frames. However, within these pipelines it is not always clear how each operation is changing the underlying data frame. To explain each step in a pipeline data science instructors resort to hand-drawing diagrams to illustrate the semantics of operations such as filtering, sorting, and grouping. In this talk, I will introduce Pandas Tutor and Tidy Data Tutor, step-by-step visual representation engines of data frame transformations. Both tools illustrate the row, column, and cell-wise relationships between an operation’s input and output data frames.

Validating and Testing R Dataframes with Pandera via reticulate - R-Python Interoperability

Presented by Niels Bantilan Original Full Title: Validating and Testing R Dataframes with Pandera via reticulate: A Case Study in R-Python Interoperability Data science and machine learning practitioners work with data every day to analyze and model them for insights and predictions. A major component of any project is data quality, which is a process of cleaning, and protecting against flaws in data that may invalidate the analysis or model. Pandera is an open source data testing toolkit for dataframes in the Python ecosystem: but can it validate R dataframes? This talk is composed of three parts: first I’ll describe what data testing is and motivate why you need it. Then, I’ll introduce the iterative process of creating and refining dataframe schemas in Pandera. Finally, I’ll demonstrate how to use it in R with the reticulate package using a simple modeling exercise as an example.

Using R, Python, and Cloud Infrastructure to Battle Aquatic Invasive Species - posit::conf(2023)

Presented by Uli Muellner and Nicholas Snellgrove Invasive species are a huge threat to lake ecosystems in Minnesota. With over 10,000 water bodies across the state, having up-to-date data and decision support is critical. Researchers at the University of Minnesota have created four complex R and Python models to support lake managers, all pulled together and presented with the most recent infestation data available. Come along with us to see how we connected these models in the AIS Explorer, a decision support application built in Shiny to help prioritize risks and placing watercraft inspectors, using tools like OCPU and cloud toolings like Lambda, EventBridge and AWS S3.

Using Data to Protect Traditional Lifeways - posit::conf(2023)

Presented by Angie Reed The spirit of Penobscot Nation’s work to protect the health of their relative, the Penobscot River, is embodied in the Penobscot water song which says ““Water, we love you, thank you so much water, we respect you.”” Because the Penobscot River is not a natural resource - she is a relative, family - this song describes the foundation of our efforts to protect her health and well-being. The identity of Penobscot people cannot be disconnected from the river, and protecting this traditional lifeway is at the heart of our work. For over a decade we have used R to manage, transform, analyze, and visualize data, and the free, open-source Posit products help us leave a legacy of good data management and the ability to share results with Penobscot Nation citizens. You will learn more about how our use of R has helped us achieve more stringent protections for the Penobscot River and how we engage young people in every step of this work. We are also part of a larger network of tribal environmental professionals, working together to learn R and share data and insights. We will give you information about how you can volunteer to help expand the network of folks providing technical assistance on any R and RStudio related topics.

USGS R Package Development: 10-year Reflections - posit::conf(2023)

Presented by Laura DeCicco Ten years ago, the first set of git commits was submitted to a new R software package repository “dataRetrieval” with the goal to provide an easy way for R users to retrieve U.S Geological Survey (USGS) water data. At that time, the perception within the USGS was the use of R was exclusive to an elite group of “very serious scientists.” Fast forward, we now find many newer USGS hires having a solid grasp of the language from the start along with the use of R in a wide variety of applications. In this talk, I’ll discuss my experiences maintaining the dataRetrieval package, how it’s shaped my career, impacted USGS R usage, and why data providers should consider sponsoring their own R packages wrapping their data API services.

tidymodels: Adventures in Rewriting a Modeling Pipeline - posit::conf(2023)

Presented by Ryan Timpe An overview of the benefits unlocked on our data science team by adopting tidymodels. Data science sure has changed over the past few years! Everyone’s talking about production. RStudio is now Posit. Models are now tidy. This talk is about embracing that change and updating existing models using the tidymodels framework. I recently completed this change, letting go of our in-production code and revisioning it with tidymodels. My team ended up with a faster, more scalable pipeline that enabled us to better automate our workflow and increase our scale while improving our stakeholders’ experiences. I’ll share tips and tricks for adopting the tidymodels framework in existing products, best practices for learning and upskilling teams, and advice for using tidymodel packages to build more accessible data science tools.

The Road to Easier Shiny App Deployments - posit::conf(2023)

Presented by Liam Kalita We’re often helping developers to assess, fix and improve their Shiny apps, and often the first thing we do is see if we can deploy the app. If you can’t deploy your Shiny app, it’s a waste of time. If you can deploy it successfully, then at the very least it runs, so we’ve got something to work with. There are a bunch of reasons why apps fail to deploy. They can be easy to fix, like Hardcoded secrets, fonts, or missing libraries. Or they can be intractable and super frustrating to deal with, like manifest mismatches, resource starvation, and missing libraries. At the end of this talk, I want you to know how to identify, investigate and proactively prevent Shiny app deployment failures from happening.

The ‘I’ in Team: Peer-to-Peer Best Practices for Growing Data Science Teams - posit::conf(2023)

Presented by Liz Roten R users don’t always come in sets. Often, you may be the only user on in the cubicle-block. But, one miraculous day, your manager finally fills the void and you welcome more folks on your team. Suddenly, the little R system you created to suit your needs, like a custom package, code styling, and file organization, isn’t just for you. Want to suddenly overhaul that one package you wrote two years ago? It probably won’t work when your colleagues try to update it. Your new teammates are data.table fans, but you prefer the tidyverse. Do you need to refactor? Are style choices, like indentation important when collaborating, or are you just being persnickety? In this talk, you will learn how to bring new teammates on board and blend your respective styles without pulling your hair out.

Thanks, I Made It with Quartodoc - posit::conf(2023)

Presented by Isabel Zimmerman When Python package developers create documentation, they typically must choose between mostly auto-generated docs or writing all the docs by hand. This is problematic since effective documentation has a mix of function references, high-level context, examples, and other content. Quartodoc is a new documentation system that automatically generates Python function references within Quarto websites. This talk will discuss pkgdown’s success in the R ecosystem and how those wins can be replicated in Python with quartodoc examples. Listeners will walk away knowing more about what makes documentation delightful (or painful), when to use quartodoc, and how to use this tool to make docs for a Python package.

I identify three main areas of challenges and show how at Universidad Nacional de San Martín (Argentina) we addressed each of the areas through a combination of original curriculum redesign, production of course materials appropriate for the students in question; and the use of OS, and some Posit products, i.e.:posit.cloud and Quarto. I show how these technologies can be used as a pedagogical tool to overcome the challenges mentioned, even on a shoestring budget.

Take it in Bits: Using R to Make Eviction Data Accessible to the Legal Aid Community - posit::conf

Presented by Logan Pratico One in five low-income renter households in the US experienced falling behind on rent or being threatened with eviction in 2021. Yet most are unrepresented when facing eviction in court. The complex and fast-paced legal system obscures access to timely information, leaving tenants without assistance. In this talk, I discuss the Civil Court Data Initiative’s use of R alongside AWS Cloud and SQL to analyze disaggregate eviction records. I focus on the integration of RMarkdown with Amazon Athena and EC2 to create weekly eviction reports across 20 states for legal aid groups working to assist tenants. The upshot: accessible eviction data to help legal aid providers better address local legal needs.

Sustainable Growth of Global Communities: R-Ladies’ Next Ten Years - posit::conf(2023)

Presented by Riva Quiroga In this talk we share how good programming practices inspire the way we manage the R-Ladies community in order to make it sustainable. R-Ladies’ first ten years were about growing the community: from being just one chapter in 2012 to becoming a global organization in 2016, and now fostering more than 230 chapters worldwide. But how can we face the challenges of growing an organization based solely on volunteer work? In this talk, we discuss how good programming practices –such as modularity, refactoring, and testing– inspire the way we see the sustainable management of an ever-growing community. To that end, we will present our most recent efforts at creating and documenting workflows, distributing the workload, and automating tasks that allow volunteers to focus their time where it is most needed. After watching this talk, you will get some ideas on how to support volunteers in your own community or project, and on how to use GitHub Actions to automate workflows and tasks.

Succeed in the Life Sciences with R/Python and the Cloud - posit::conf(2023)

Presented by Colby Ford This talk covers best practices and lessons learned surrounding the use of R and Python by technical teams in the cloud, focusing on Posit Workbench, Azure ML, and Databricks. In the life sciences, whether it’s pharma, biotech, research, or another type of organization, we are unique in that we blend scientific knowledge with technical skills to extract insights from large, complex datasets. In the cloud, we can architect solutions to help us scale, automate, and collaborate. Interestingly, the use of R and Python by bioinformatics, genomics, biostatistics, and data science teams can be challenging in a cloud-first world where all the data is somewhere other than your laptop (like a data lake). In this talk, I will share best practices and lessons learned surrounding the use of R and Python by technical teams in the cloud. We’ll focus on the use of Posit Workbench and RStudio on various cloud services such as Azure ML and Databricks.

Styling and Templating Quarto Documents - posit::conf(2023)

Presented by Emil Hvitfeldt Quarto is a powerful engine to generate documents, slides, books, websites, and more. The default aesthetics looks good, but there are times when you want and need to change how they look. This is that talk. Whether you want your slides to stand out from the crowd, or you need your documents to fit within your corporate style guide, being able to style Quarto documents is a valuable skill. Once you have persevered and created the perfect document, you don’t want the effort to go to waste. This is where templating comes in. Quarto makes it super easy to turn a styled document into a template to be used over and over again.

Speeding Up Plots in R/Shiny - posit::conf(2023)

Presented by Ryszard Szymański A slow plots can ruin the user experience of our dashboard. This talk covers techniques for speeding up the rendering process of our visualisations. Slow dashboards lead to a poor user experience and cause users to lose interest, or even become frustrated. A common culprit of this situation is a slowly rendering plot. During the talk, we will dive deeper into how plots are rendered in Shiny, identify common bottlenecks that can occur during the rendering process, and learn various techniques for improving the speed of plots in R/Shiny dashboards. These techniques will range from more efficient data processing to library-specific optimisations at the browser level.

Solving a Secure Geocoding Problem (That Hardly Anybody Has) - posit::conf(2023)

Presented by Tesla DuBois Due to data security concerns, the strictest health researchers won’t send patient addresses to remote servers for geocoding. The only existing methods for offline geocoding are expensive, cumbersome, or require working with code - all limiting factors for many researchers. So, a couple of classmates and I made a standalone desktop application using shell, Docker, PostGIS, and Python to geocode addresses through a simple GUI without ever sending them off the local machine.

Small Package, Broad Impact: How I Discovered the Ultimate New Hire Hack - posit::conf(2023)

Presented by Trang Le Onboarding new hires can be a challenging process, but taking a problem-focused approach can make it more meaningful and rewarding. In this talk, I will share how I discovered the ultimate new hire hack by creating two small packages that gave me the confidence I needed when I started at BMS. Through building these packages, I not only learned R things like using bslib and making font files available for published dashboards, but also gained a deep understanding of my company’s internal systems and workflows, and connected with my team via lots of questions. The resulting packages are still heavily used today. Join me to discover how small packages can have a broad impact and what hiring managers can do to help.

Siuba and duckdb: Analyzing Everything Everywhere All at Once - posit::conf(2023)

Presented by Michael Chow Every data analysis in Python starts with a big fork in the road: which DataFrame library should I use? The DataFrame Decision locks you into different methods, with subtly different behavior:: different table methods (e.g. polars.with_columns() vs pandas.assign()) different column methods (e.g. polars.map_dict() vs pandas.map()) In this talk, I’ll discuss how siuba (a dplyr port to python) combines with duckdb (a crazy powerful sql engine) to provide a unified, dplyr-like interface for analyzing a wide range of data sources‚ whether pandas and polars DataFrames, parquet files in a cloud bucket, or pins on Posit Connect. Finally, I’ll discuss recent experiments to more tightly integrate siuba and duckdb.

Shiny New Tools for Scaling your Shiny Apps - posit::conf(2023)

Presented by Joe Kirincic So you have a Shiny app your org loves, but as adoption grows, performance starts getting sluggish. Profiling reveals your cool interactive plots are the culprit. What can you do to make things snappy again? We can increase the number of app instances, sure, but suppose that isn’t an option for us. Another approach is to shift the plotting work from the server onto the client. In this talk, we’ll learn how to leverage two Javascript projects, DuckDB-WASM and Observable’s Plot.js, in our Shiny app to create fast, flexible interactive visualizations in the browser without burdening our app’s server function. The end result is an app that can scale to more users without needing to increase compute resources.

Running R-Shiny without a Server - posit::conf(2023)

Presented by Joe Cheng A year ago, Posit announced ShinyLive, a deployment mode of Shiny that lets you run interactive applications written in Python, without actually running a Python server at runtime. Instead, ShinyLive turns Shiny for Python apps into pure client-side apps, running on a pure client-side Python installation. Now, that same capability has come to Shiny for R, thanks to the webR project. In this talk, I’ll show you how you can get started with ShinyLive for R, and why this is more interesting than just cheaper app hosting. I’ll talk about some of the different use cases we had in mind for ShinyLive, and help you decide if ShinyLive makes sense for your app. Presented at Posit Conference, between Sept 19-20 2023, Learn more at posit.co/conference.# Talk Track: I can’t believe it’s not magic: new tools for data science.

Open Source Solutions to Next-Generation Submissions, After 30 Years of Industry Experience

Presented by Mike K Smith The pharmaceutical industry is undergoing rapid change, driven by a desire from both industry and regulatory agencies to move to more interactive visualizations and web applications to review data and make decisions. These changes would have been unthinkable 30 years ago when I started working at Pfizer. In this talk, I’ll consider the drivers for these changes, how open-source tools can help achieve this, and why collaboration across the industry is vital to achieving this goal. I’ll contrast this with my experience of 30 years working in the pharma industry - when the R language had only just been released, when the internet was new, and when submissions to agencies were printed out, loaded onto trucks, and shipped to their doors.

Oops I’m a Manager - On More Effective 1-on-1 Meetings - posit::conf(2023)

Presented by Andrew Holz As a team leader (accidental or not), it’s easy to get caught up in the daily grind and overlook the importance of 1-on-1s. Bad idea. 1-on-1s are critical for building trust, providing feedback, and ensuring that everyone is on the same page. Keys to good 1-on-1s start with a small amount of prep and a running shared document of notes and takeaways. Another key is to rotate types of 1-on-1s. Possibilities include “heads down” on recent work, “heads up” looking further out, and career-focused sessions. After some tips on the right sort of questions and uncovering sneaky issues, I will also touch on effective feedback. I will share resources and hope to include Seussian visuals and a few poetic lines to help the key points stick.

Never again in outer par mode: making next-generation PDFs with Quarto & typst - posit::conf(2023)

Presented by Carlos Scheidegger Quarto 1.4 will introduce support for Typst. Typst is a brand-new open-source typesetting system built from scratch to support the lessons we have learned over almost half a century of high-quality computer typesetting that TeX and LaTeX have enabled. If you’ve ever had to produce a PDF with Quarto and got stuck handling an inscrutable error message from LaTeX, or wanted to create a new template but were too intimated by LaTeX’s arcane syntax, this talk is for you. I’ll show you why we need an alternative for TeX and LaTeX, and why it will make Quarto even better.

Motley Crews: Collaborating with Quarto - posit::conf(2023)

Presented by Susan McMillan, Wyl Schuth, and Michael Zenz Adoption of Quarto for document creation has transformed the collaborative workflow for our small higher-education analytics team. Historically, content experts wrote in Word documents and data analysts used R for statistics and graphics. Specialization in different software tools created challenges for producing collaborative analytic reports, but Quarto has solved this problem. We will describe how we use Quarto for writing and editing text, embedding statistical analysis and graphics, and producing reports with a standard style in multiple formats, including web pages.

Magic with WebAssembly and webR - posit::conf(2023)

Presented by George Stagg Earlier this year the initial version of webR was released and users have begun building new interactive experiences with R on the web. In this talk, I’ll discuss webR’s TypeScript library and what it is able to do. The library allows users to interact with the R environment directly from JavaScript, which enables manipulation tricks that seem like magic. I’ll begin by describing how to move objects from R to JS and back again, and discuss the technology that makes this possible. I’ll continue with more advanced manipulation, such as invoking R functions from JS and talk about why you might want to do so. Finally, I’ll describe how messages are sent over webR’s communication channel and explain how this enables webR to work with Shinylive.

Large Language Models in RStudio - posit::conf(2023)

Presented by James Wade Large language models (LLMs), such as ChatGPT, have shown the potential to transform how we code. As an R package developer, I have contributed to the creation of two packages – gptstudio and gpttools – specifically designed to incorporate LLMs into R workflows within the RStudio environment. The integration of ChatGPT allows users to efficiently add code comments, debug scripts, and address complex coding challenges directly from RStudio. With text embedding and semantic search, we can teach ChatGPT new tricks, resulting in more precise and context-aware responses. This talk will delve into hands-on examples to showcase the practical application of these models, as well as offer my perspective as a recent entrant into public package development.

It’s All About Perspective: Making a Case for Generative Art - posit::conf(2023)

Presented by Meghan Santiago Harris This talk explores how to create art in the R language while highlighting some similarities between the skills required for creating generative art and those needed to perform data science tasks in R. Because the field of data science is inherently task-oriented, it is no wonder that most people struggle to see the utility of generative art past the bounds of a casual hobby. This talk will invite the participant to learn about generative art while focusing on ““why”” people should create it and its potential place in data science. This talk is suitable for all disciplines and artistic abilities. Furthermore, this talk will aim to expand the participant’s perspective on generative art with the following concepts: What is generative art and how can it be created in R or Python Justifications for generative art within Data Science Examples of programming skills that are transferrable between generative art and pragmatic data science projects Materials: Link to the talk repo: https://github.com/Meghansaha/a_case_for_genart Link to the slides: https://meghansaha.github.io/a_case_for_genart/#/title-slide Link to the artpack package site: https://meghansaha.github.io/artpack/ Personal Site: https://thetidytrekker.com/ Presented at Posit Conference, between Sept 19-20 2023, Learn more at posit.co/conference.# Talk Track: Developing your skillset; building your career.

It’s Abstractions All the Way Down… - posit::conf(2023)

Presented by JD Long Abstractions rule everything around us. JD Long talks about abstractions from the board room to the silicon. Over 20 years ago Joel Spolsky famously wrote, “All non-trivial abstractions, to some degree, are leaky.” Unsurprisingly this has not changed. However, we have introduced more and more layers of abstraction into our workflows: Virtual Machines, AWS services, WASM, Docker, R, Python, data frames, and on and on. But then on top of the computational abstractions we have people abstractions: managers, colleagues, executives, stakeholders, etc. JD’s presentation will be a wild romp through the mental models of abstractions and discuss how we, as technical analytical types, can gain skill in traversing abstractions and dealing with leaks.

It’s a Great Time to be an R Package Developer! - posit::conf(2023)

Presented by Jenny Bryan and Hadley Wickham (Due to unforeseen circumstances, Hadley Wickham presented this talk “slide karaoke” style, from materials prepared by Jenny Bryan.) In R, the fundamental unit of shareable code is the package. As of March 2023, there were over 19,000 packages available on CRAN. Hadley Wickham and I recently updated the R Packages book for a second edition, which brought home just how much the package development landscape has changed in recent years (for the better!). In this talk, I highlight recent-ish developments that I think have a great payoff for package maintainers. I’ll talk about the impact of new services like GitHub Actions, new tools like pkgdown, and emerging shared practices, such as principles that are helpful when testing a package.

Insights in 5-D! (Using magic small-multiples layouts) - posit::conf(2023)

Presented by Matt Dzugan Using Small-Multiples (faceted graphs) is an effective way to compare patterns across many dimensions. In this talk, I’ll walk you through some ways to lay out your individual facets according to the underlying data. For example, maybe each facet represents a city or point on a 2D plane - we’ll explore ways to organize facets in a grid that mimics the data itself - unlocking your ability to explore patterns in 4+ dimensions. Other solutions to this problem rely on manually-curated lists that map common layouts to a grid, but in this talk, we’ll explore solutions that work on EVERYTHING. I’ll show you how to incorporate this technique into your viz and how I built the libraries since there are some interesting data science concepts at play.

HTML and CSS for R Users - posit::conf(2023)

Presented by Albert Rapp You can get the most out of popular R tools by combining them with easy-to-learn HTML & CSS commands. It’s easy to think that R users do not need HTML and CSS. After all, R is a language designed for data analysis, right? But the reality is that these web standards are everywhere, even in R. In fact, many great tools like {ggtext}, {gt}, {shiny}, and Quarto unlock their full potential when you know a little bit of HTML & CSS. In this talk, I will demonstrate specific examples where R users can benefit from HTML and CSS and show you how to get started with these two languages.

How to Win Friends and Influence People (With Data) - posit::conf(2023)

Presented by Joe Powers Too many great data science products never go into production. To persuade leaders and colleagues to adopt your data science offering, you must translate your insights into terms that are relevant and accessible to them. Attempts to persuade these audiences with proofs and model performance stats will often fall flat because the audience is left feeling overwhelmed. This talk will demonstrate the data simulation, visualization, and story-telling techniques that I use to influence leadership and the community-building techniques I use to earn the trust and support of fellow analysts.

Github Copilot integration with RStudio, it’s finally here! - posit::conf(2023)

Presented by Tom Mock This talk closes issue #10148, “Github Copilot integration with RStudio”, the most upvoted feature request in RStudio’s history. Code generating AI tools like Github Copilot‚ promise an “AI pair programmer that offers autocomplete-style suggestions as you code”. For the first time, we’ll show a native integration of Copilot into RStudio, helping to build on that promise by providing AI-generated “ghost text” autocompletion with R and other languages. I’ll also provide a comparison of Copilot’s “ghost text” to a chat-style interface in RStudio via the {chattr} package from the Posit MLVerse team. To make the most of these new features, I’ll walk through some examples of how sharing additional context, comments, code, and other “prompt engineering” can help you go from code-generating AI tools that feels like an annoying backseat driver to an experienced copilot. We’ll close with a robust end-to-end example of how these new RStudio integrations and packages can help you be a more productive developer.

From Novices to Experts: Building a Community of Engaged R Users - posit::conf(2023)

Presented by Natalia Andriychuk At Pfizer, we have over 1500 users with R installed on their machines, along with an R community on MS Teams comprising over a thousand colleagues globally. How can we effectively engage with Pfizer R users and celebrate the successes of this community, while sharing best practices? Additionally, how do we avoid isolated groups duplicating efforts to solve R-related problems across different parts of the organization? To address these challenges, we established the Pfizer R Center of Excellence (CoE) in early 2022.

From Journalist to Coder: Creating a Web Publication with Quarto - posit::conf(2023)

Presented by Brian Tarran This is the story of how a Royal Statistical Society writer discovered Quarto, learned how to code (a bit), and built realworlddatascience.net, an online publication for the data science community. In March 2022, I was tasked by the Royal Statistical Society with creating a new online publication: a data science website for data science professionals. I’ve been a print journalist for 20 years and have worked on websites in that time, but my coding ability began and ended with wrapping href tags around text and images. That is until I discovered Quarto. In this talk, I describe how I explored, learned, and fell in love with the Quarto publishing system, how I used it to build a website – Real World Data Science (realworlddatascience.net) – and how the open source community mindset helped shape my thinking about what a new publication could and should be!

Dynamic Interactions: webR to Empower Educators & Researchers with Interactive Quarto Docs

Presented by James Balamuta Full talk title: Dynamic Interactions: Empowering Educators and Researchers with Interactive Quarto Documents Using webR Traditional Quarto documents often lack interactivity, limiting the ability of students and researchers to fully explore and engage with the presented topic. In this talk, we propose a novel approach that utilizes webR, a WebAssembly-powered version of R, to seamlessly embed R code directly within the browser without the need for a server. We demonstrate how this approach can transform static Quarto documents into dynamic examples by leveraging webR’s capabilities through standard Quarto code cells, enabling real-time execution of R code and dynamic display of results. Our approach empowers educators and researchers alike to harness the power of interactivity and reproducibility for enhanced learning and research experiences.

duckplyr: Tight Integration of duckdb with R and the tidyverse - posit::conf(2023)

Presented by Kirill Müller The duckplyr R package combines the convenience of dplyr with the performance of DuckDB. Better than dbplyr: Data frame in, data frame out, fully compatible with dplyr. duckdb is the new high-performance analytical database system that works great with R, Python, and other host systems. dplyr is the grammar of data manipulation in the tidyverse, tightly integrated with R, but it works best for small or medium-sized data. The former has been designed with large or big data in mind, but currently, you need to formulate your queries in SQL. The new duckplyr package offers the best of both worlds. It transforms a dplyr pipe into a query object that duckdb can execute, using an optimized query plan. It is better than dbplyr because the interface is “data frames in, data frames out”, and no intermediate SQL code is generated. The talk first presents our results, a bit of the mechanics, and an outlook for this ambitious project.

Diversify Your Career with Shiny for Python - posit::conf(2023)

Presented by Gordon Shotwell A few years ago my company made a sudden shift from R to Python which was quite bad for my career because I didn’t really know Python. The main issue was that I couldn’t find a niche that allowed me to use my existing knowledge while learning the new language. Shiny for Python is a great niche for R users because none of the Python web frameworks can do what Shiny can do. Additionally, almost all of your knowledge of the R package is applicable to the Python one. This talk will provide an overview of the Python web application landscape and articulate what Shiny adds to this landscape, and then go through the five things that R users need to know before developing their first Shiny for Python application.

Democratizing Access to Education Data - posit::conf(2023)

Presented by Erika Tyagi Learn how the Urban Institute is making high-quality data more accessible through the Education Data Portal. Every year, government agencies release large amounts of data on schools and colleges, but this information is scattered across various websites and is often difficult to use. To make these data more accessible, the Urban Institute built the Education Data Portal, a freely available one-stop shop for harmonized data and metadata for nearly all major federal education datasets. In this talk, we’ll demonstrate how the portal works and share lessons we’ve learned about making data accessible to users with varying technical skills and preferred programming languages.

dbtplyr: Bringing Column-Name Contracts from R to dbt - posit::conf(2023)

Presented by Emily Riederer starts_with(language): Translating select helpers to dbt. Translating syntax between languages transports concepts across communities. We see a case study of adapting a column-naming workflow from dplyr to dbt’s data engineering toolkit. dplyr’s select helpers exemplify how the tidyverse uses opinionated design to push users into the pit of success. The ability to efficiently operate on names incentivizes good naming patterns and creates efficiency in data wrangling and validation. However, in a polyglot world, users may find they must leave the pit when comparable syntactic sugar is not accessible in other languages like Python and SQL. In this talk, I will explain how dplyr’s select helpers inspired my approach to ‘column name contracts,’ how good naming systems can help supercharge data management with packages like {dplyr} and {pointblank}, and my experience building the {dbtplyr} to port this functionality to dbt for building complex SQL-based data pipelines.

Data Science in Production: The Way to a Centralized Infrastructure - posit::conf(2023)

Presented by Oliver Bracht In this talk, the success story of Covestro’s posit infrastructure is presented. The problem of the leading German material manufacturer was that no common development environment existed. With the help of eoda and Posit, a replicable, centralized development environment for R and Python was created. Although R and Python represent the core of the infrastructure, multiple languages and tools are unified. In addition to the collaboration of Covestro’s data science teams, compliance guidelines could also be better fulfilled. The staging architecture hereby provides developers with a concept for testing and going live with their products.

Building a Flexible, Scaleable Self-Serve Reporting System with Shiny - posit::conf(2023)

Presented by Natalie O’Shea Working in the high-touch world of consulting, our team needed to develop a reporting system that was flexible enough to be tailored to the specific needs of any given partner while still reducing the highly manual nature of populating client-ready slide decks with various metrics and data visualizations. Utilizing the extensive resources developed by the R user community, I was able to create a flexible, scalable reporting system that allows users to populate templated Google slide decks with metrics and professional-grade visualizations using data pulled directly from our database at the time of query. This streamlined approach enables our consultants to spend less time copy-pasting data from one channel to another and instead focus on what they do best: surfacing business-relevant insights and recommendations for our partners. By sharing my approach to customizable self-serve reporting in Shiny, I hope attendees will walk away with new ideas about how to combine parameterized reporting and dashboard development to get the best of both worlds. Additionally, I hope to end by sharing how this project was pivotal in making the business case for procuring Posit products for my broader organization.

Becoming an R Package Author (or How I Got Rich Responding to GitHub Issues) - posit::conf(2023)

Presented by Matt Herman The transition from analyzing data in R to making packages in R can feel like a big step. Writing code to clean data or make visualizations seems categorically different from building robust “software” on which other people rely. In this talk, I’ll show why that distinction is not necessarily true by discussing my personal experience from learning R in graduate school to reporting bugs on GitHub to becoming a co-author of the tidycensus package and a practicing data scientist. The positive and supportive R community on GitHub, Twitter, and elsewhere contributes to why anyone who writes R code can become a package author. I have not actually gotten rich but I did get freelance data work based on my package contributions!

Automating the Dutch National Flu Surveillance for Pandemic Preparedness - posit::conf(2023)

Presented by Patrick van den Berg The next pandemic may be caused by a flu strain, and with thousands of patients with the flu in Dutch hospitals annually it is important to have accurate and current data. The National Institute for Public Health and the Environment of the Netherlands (RIVM) collects and processes flu data to achieve pandemic preparedness. However, the flu reporting process used to be very laborious, stealing precious time from epidemiologists. In our journey of automating this data pipeline we learned that collaboration was the most important factor in getting to a working system. This talk will be at the cross-section of data science and epidemiology and will provide you with a valuable opportunity to learn from our experiences.

Adding a Touch of glitr: Developing a Package of Themes on Top of ggplot - posit::conf(2023)

Presented by Aaron Chafetz and Karishma Srikanth Please note, a power issue cut off the first five minutes of the talk. Explore how our team at the US Agency for International Development (USAID) created our own data viz branding R package on top of ggplot2 and how you can too. How do you create brand cohesion across your large team when it comes to data viz? Inspired by the BBC’s bbplot, our team at the US Agency for International Development (USAID) developed a package on top of ggplot2 to create a common look and feel for our team’s products. This effort improved not just the cohesiveness of our work, but also trustworthiness. By creating this package, we reduced the reliance on using defaults and the time spent on each project customizing numerous graphic elements. More importantly, this package provided an easier on-ramp for new teammates to adopt R. We share our journey within a federal agency developing a style guide and aim to guide and inspire other organizations who could benefit from developing their own branding package and guidance.

{slushy}: A Bridge to the Future - posit::conf(2023)

Presented by Becca Krouse Scaling the use of R can present complications for environment management, especially in regulated industries with a focus on traceability. One solution is controlled (aka “frozen”) environments, which are carefully curated and tested by tech teams. However, the speed of R development means the environments quickly become outdated and users are unable to benefit from the latest advances. Enter {slushy}: a team-friendly tool powered by {renv} and Posit Package Manager. Users can quickly mimic a controlled environment, with the easy ability to time travel between snapshot dates. Attendees will learn how {slushy} bolstered our R adoption efforts, and how this strategy enables tech teams and users to work in parallel towards a common future.

Shiny in Production 2023: George Stagg - R Shiny without a server: webR and Shinylive

R Shiny without a server: webR and Shinylive by George Stagg at the Shiny in Production 2023 conference, hosted by Jumping Rivers! Note from the speaker: Shinylive is now available on CRAN! https://cran.r-project.org/web/packages/shinylive/index.html Abstract# WebAssembly (Wasm) is a technology that enables software that’s normally compiled for a specific computer system to instead run anywhere, including inside web browsers. WebR is a version of the R interpreter compiled for Wasm, bringing this technology to the R world. Earlier this year, the initial version of webR was released and users have already begun building new interactive experiences with R on the web. The latest release, version 0.2.0, includes improvements to graphics, accessibility and internationalisation, developer API updates, and introduces a new webR REPL app. The release also includes expanded support for Wasm R packages, including the ability to run fully client‐side Shiny apps. In this talk, I’ll introduce webR with some simple examples and discuss some details of how the system works. I’ll talk about how JavaScript APIs can be used to integrate webR into wider web applications and describe webR’s communication channel. Finally, I’ll give a description of how Shiny apps can be run using webR without an R server, ending with a demo of an in‐development “Shinylive for R”.

How the R for Data Science (R4DS) Online Learning Community Made Me a Better Student - posit::conf

Presented by Lydia Gibson Through my participation in R4DS Online Learning Community, I have advanced my R and data science skills, making me a better student than I otherwise would have been through just my studies. As a non-traditional MS Statistics student with an undergraduate background in economics, I had absolutely no experience with the R programming language prior to pursuing my Master’s degree. In July 2021, with hopes of getting a headstart on learning R before beginning my degree program, I joined the R4DS Slack Workspace. Along with helping to improve my programming skills, R4DS has connected me with scholarships, mentorship, and other opportunities, and I think that it would be beneficial for other students to know about this great resource.

Eric Nantz, Alex Lauer, Rich Iannone - A Pivotal Year of Milestones in R Consortium Working Groups

A Pivotal Year of Milestones: R Submissions Working Group and R Tables for Regulatory Submissions updates - Eric Nantz, Alexandra Lauer, and Rich Iannone Resources mentioned in the presentation: R Submissions Working Group: https://rconsortium.github.io/submissions-wg/ R Tables eBook: https://rconsortium.github.io/rtrs-wg Abstract: Within the life sciences industry, Shiny has enabled tremendous innovations to produce web interfaces as frontends to sophisticated analyses, dynamic visualizations, and automation of clinical reporting across drug development. While industry sponsors have widely adopted Shiny as part of their analytics and reporting toolset, a relatively unexplored frontier has been the inclusion of a Shiny application inside a clinical submission package to regulatory agencies such as the FDA. The R Consortium R Submissions Working Group has continued the positive momentum of previous submission pilots to achieve substantial progress in this domain. In this talk, we will share the development journey of the working group’s Pilot 2 successful submission of a Shiny application to the FDA, along with the progress on the use of novel technologies such as Linux containers and web assembly to bundle a Shiny application into a self-contained package, facilitating a smoother process of both transferring and executing the application. The R Consortium’s R Tables for Regulatory Submissions (RTRS) Working Group has released the first edition of (Tables in Clinical Trials with R)[ https//rconsortium.github.io/rtrs-wg/] as a free and openly accessible ebook. The book contributes to the development of a theory of displaying tabular information by identifying a small number of table archetypes that may be used to generate the most common tables employed in clinical submissions. Chapters in the book demonstrate how these tables may be rendered in different R Packages including flextable, gt, rtables (with and without tern), tables, tfrmt and tidytlg. All tables are generated from CDISC-compliant data. Comparing the code showcases the robustness of R for aggregating and displaying tabular information and illuminates the flexibility and design tradeoff of the various R packages. The talk will discuss the motivation for the book, present the idea of table archetypes, show some representative tables, and make the case for R as a superb language for analyzing clinical trial data. The RTRS working group expects Tables in Clinical Trials with R to become a primary resource of clinical programming teams. Speaker Bios: Eric Nantz is a director within the statistical innovation center at Eli Lilly and Company, creating analytical pipelines and capabilities of advanced statistical methodologies for clinical design used in multiple phases of development. Outside of his day job, Eric is passionate about connecting with and showcasing the brilliant R community in multiple ways. You may recognize his voice from the R-Podcast that he launched in 2012. Eric is also the creator of the Shiny Developer Series where he interviews authors of Shiny-related packages and practitioners developing applications, as well as sharing his own R and Shiny adventures via livestreams on his Twitch channel. In addition, Eric is a curator for the RWeekly project and co-host of the RWeekly Highlights podcast which accompanies every issue. Alexandra Lauer is a Senior Principal Statistical Analyst at Merck KGaA, Darmstadt, Germany, with a background in mathematics. She specializes in bridging psychometrics and biostatistics, with a primary focus on Health-Related Quality of Life evaluations. Alex is an R enthusiast, co-leading the Merck-internal R User Group. Rich Iannone: My background is in programming, data analysis, and data visualization. Much of my current software engineering work on R packages is intended to make working with data easier. I truly believe that with the right approach, tools like these can be both powerful and easy to use. Presented at the 2023 R/Pharma Conference (October 26, 2023)

“Shiny: Data-centric web applications in Python” - Joe Cheng (PyBay 2023)

Joe Cheng https://pybay.com/speakers/#sz-speaker-7e5324de-3afa-4614-a498-562bd5eb9986 Shiny is a web framework that is designed to let you create data dashboards, interactive visualizations, and workflow apps in pure Python or R. Shiny doesn’t require knowledge of HTML, CSS, and JavaScript, and lets you create data-centric applications in a fraction of the time and effort of traditional web stacks. Of course, Python already has several popular and high-quality options for creating data-centric web applications. So it’s fair to ask what Shiny can offer the Python community. In this talk, I will introduce Shiny for Python and answer that question. I’ll start with some basic demos that show how Shiny apps are constructed. Next, I’ll explain Transparent Reactive Programming (TRP), which is the animating concept behind Shiny, and the reason it occupies such an interesting place on the ease-vs-power tradeoff frontier. Finally, I’ll wrap up with additional demos that feature interesting functionality that is made trivial with TRP. This talk should be interesting to anyone who uses Python to analyze or visualize data, and does not require experience with Shiny or any other web frameworks. PyBay features the most influential speakers presenting the most crucial technologies to help beginners and seasoned developers alike get up-to-date quickly, in a single-track format. Whether you’re interested in web technologies, data, devops, Python internals, or performance, PyBay will help you stay on top of your game AND network with engineers at companies that are hiring!

The River is our Relative | The Story of the Penobscot Nation

The Penobscot Nation has been around for millennia. On Indian Island, a river gives the Penobscot people life. “The tribe views the river like its own highway. We look at her as a relative, a sister, someone that gives life. Sea Lamprey, Sturgeon, Striper Bass.” Jan Paul works for the Penobscot Nation in the Department of Natural Resources and Water Quality. She’s using open-source technology, like R and the RStudio IDE, to keep the river healthy, so in turn, it can keep her people healthy. This is Jan’s inspiring story, featured for the first time at posit::conf(2023).

Michael Lopez @ NFL | Being forward-thinking & anticipating questions | Data Science Hangout

We were recently joined by Michael Lopez, Sr. Director of Football Data & Analytics at the National Football League to discuss using data and analytics to enhance the game of football. Timestamps: 4:29 - The process of using RFID tag data 7:31 - What kind of decision making is your work driving? 9:00 - Do you analyze player’s health stats? 11:39 - How transferrable are sports analytics skills across leagues? 14:19 - Big Data Bowl and other community initiatives 19:20 - Structured vs unstructured data? 21:51 - Transition from academia to NFL 25:23 - Communication skills that have transferred over 29:22 - What data is captured from the RFID tags? 34:32 - How could someone get into the NFL space as a data scientist focused on health? 37:18 - How are you getting people to buy-in to analytics? 40:40 - How do you prioritize what your team is working on? 43:04 - Languages and tools used in analytics at the NFL 45:06 - Translator role in football analytics 49:09 - How does the NFL go about achieving the level of analytics that you do? 50:59 - Does GAIT analysis have impact on their performance? 52:59 - How do you evangelize new data points and explore things previously un-explored? 55:48 - Fantasy football 56:34 - What are you excited about in the year ahead? Diving into a specific topic on communication – 27:38 “Sometimes we are answering the questions that we know they’re going to ask before they’ve asked them. And I think the best presentations we give are the ones where they’re asking a question and then just click Next, and it’s on the next slide. Or they ask a question and I say, yep, it’s in the Appendix. Click a couple slides forward and say, here it is. Because you have to anticipate the questions they’re going to ask. Sometimes, we’re collecting data before they’ve asked us to collect data because we hear something in the media or we hear something that they’re asking in the replay room or their coaches are asking, and we’re like, we’re going to go build this. They didn’t tell us to go collect data on quarterback slides, but we now know that quarterbacks are sliding more than ever before. We know quarterbacks are the most important position in football. So last year, Andrew Patton basically led an NFL data collection processing quarterback slides. Because we knew that when we got to the offseason, somebody was going to say, “hey, how are how are quarterbacks sliding?” Actually, we have that because we went out and collected it. So I would say that it’s a combination of great data viz and then also being purposeful and forward-thinking with the questions that people are going to be wanting to ask. ► Subscribe to Our Channel Here: https://bit.ly/2TzgcOu Follow Us Here: Website: https://www.posit.co LinkedIn: https://www.linkedin.com/company/posit-software Twitter: https://twitter.com/posit_pbc To join future data science hangouts, add to your calendar here: pos.it/dsh (All are welcome!

Hadley Wickham @ Posit | Giving benefit to people using what you build | Data Science Hangout

We were recently joined by Hadley Wickham, Chief Scientist at Posit PBC. Listen in to hear our chat about building tools (like the tidyverse) to make data science easier, faster, and more fun. 36:57 - While I’m bought into developing open source packages to help deliver better processes, any advice to those of us doing that development in getting their company bought in? You have to give some benefit to the people using (what you’re building) You’ve got to either remove pain or add pleasure in some way because if you can’t do that and you’re not someone’s direct supervisor, it’s hard to get people to change. The way I think about the tidyverse is, how do we give people some sort of quick wins so they can be motivated to do the things that are slower where they’re gonna have to learn some new ideas or some new tools. You kind of build up some equity with that person. They build trust that you’ve helped them in the past and now they’re willing to invest a little bit more time before they see the payoff. But in the early days, it’s all about delivering payoffs as quickly as possible. And I think if you’re doing, like, you know “my company’s first R package” - the easy pain points are: make themes for your company corporate style guide, make a ggplot2 theme, make an R Markdown, a Quarto theme. Make a Shiny theme that people can just use to get, you know, something that’s reasonably close to whatever your corporate style guide dictates. That just feels like an easy win for people because it makes them look good inside the corporation and because you’ve put in all the hard work, it’s like three seconds for them to type the right function name to get the right theme. I think the other bit is making it easier to get access to data. Set up some wrappers around DBI connections to the most important data sources. Provide some conventions around authentication so that stuff just works so that they’re not struggling with “What packages do I need to install? What’s the password? Where’s the path I need?” Just give them some, like, a list of the top ten most common data sources and people will love you by and large. Follow-up question: Once you identify the things that you think would be useful for people - do you have a philosophy or a way in which you approach putting things together? When you’re in an environment of scarcity when you’ve only got so much time that you can take out of your everyday job to invest in writing a package, it’s really tough to balance. Like, how do I add new stuff versus making sure the old stuff continues to work? I think, again, some of it’s about building up trust. So, give people some wins so that when you inevitably break stuff, you’ve got some kind of cushion so people aren’t going to be really angry with you right away. They’re gonna be like, ok, well there’s a little bit of suffering now, but this person saved me so much time. But yeah, it’s really hard. And particularly as you’re starting out, like, you’re going to make mistakes. That’s inevitable. You’re going to do things that when you look back a year later, you’re like, why on earth did I do it that way? You’ll want to rip out the whole thing and ride it from scratch. And I think that if it feels horrible, you have to remember, that’s great. It means you’ve grown immensely as a programmer. Certainly if you have my kind of mindset, you have to resist the temptation to rip things out and redo them as much as possible and just focus on making the next generation better rather than breaking what stuff people already have. So I don’t have any great answers here, but I think you just have to think about those tensions of “how do I keep my forward velocity up while getting better as a programmer and evolving over time, but also thinking about how do you make the things you did a long time ago better?” ► Subscribe to Our Channel Here: https://bit.ly/2TzgcOu Follow Us Here: Website: https://www.posit.co LinkedIn: https://www.linkedin.com/company/posit-software Twitter: https://twitter.com/posit_pbc To join future data science hangouts, add to your calendar here: pos.it/dsh (All are welcome!

RStudio IDE | Background and Posit Workbench Jobs

This is a great feature for any long running scripts you may have, including, for example, a machine learning training step. It also allows you to run multiple jobs simultaneously. Now the main difference between background jobs and workbench jobs is that background jobs run as a child process within the same session. And workbench jobs run as a new session, either on the local server, or off host if you’re running in a multi server or clustered environment

Joe Cheng @ Posit | You have to be able to reason about it | Data Science Hangout

We were recently joined by Joe Cheng, CTO at Posit PBC to chat about all things Shiny - a web framework for data scientists, career journeys, being vulnerable, and so much more. At 39:53 - Joe shared what it means when he says, “you have to be able to reason about it” When you write software or do an analysis or whatever, there’s a level of “I got it to work” and then there’s the level of “it works, and I can reason about it.” Complex pieces of software are among the most complicated things that humankind has ever devised. What other human-made constructs can have hundreds of millions of pieces and yet they’re expected to all fit and work together so precisely that, if one token is off, rockets explode. I don’t know what the limit is, but even the smartest humans can only hold some small number of variables and operations in their head at any one time. When we work on software that’s non-trivial, we work on software that in its totality is more than any one human mind can hold at any one given time. The main challenge in software engineering is about, how do you take all this complexity and break it down into smaller pieces, each of which you can reason about, each of which you can hold in your head, each of which you can look at and say, “Yeah, I can fully ingest this entire function definition. I can read it, line by line, and prove to myself, this is definitely correct if the functions that it’s calling don’t have bugs and if it’s called in the right way.” So with those caveats, if the things that this is calling are correct and are called correctly, then the result will be correct because the logic here is correct. Software engineering, at all but the most beginner level, is a lot about this. How do you break up inherently complicated things that we’re trying to do into small pieces that are individually easy to reason about? That’s half the battle right there. The other half of the battle is - how do we combine them in ways that can be reliable and also easy to reason about? So it’s these two pieces– small pieces reliably composed– if you can achieve that, that’s what I’m talking about. That’s software that you can reason about. This has implications for data science as well. With data science, you’re doing some kind of analysis on some data, and it starts out as, oh, I’m just doing these simple things. I’m doing this manipulation and then I’m doing this visualization. But then as you get deeper and deeper into it, it grows and grows and grows. You’re at the point where you’re at the end and you don’t remember where these variables came from. You don’t remember what’s the difference between this data frame and this data frame. And you go back and hopefully start breaking it into functions or somehow dividing it into smaller pieces that each focus on a thing. Then you join those pieces together in your overall script. That’s this principle of small pieces individually able to be reasoned about. When you think about other rules that you might have heard about software engineering – we know when you’re writing functions, using global variables is bad. That’s another one of these things where that hurts your ability to hold the entire function in your head and to prove that it’ll work correctly. Because who knows who is setting that global variable to what value? You can’t prove to yourself this function is definitely correct. I think if there’s anything that you’re working on that needs to be correct and you do care that the answer is right, I try never to stop when I have an answer but I can’t reason about the code. I always try to go back and do the refactoring that’s necessary just so I can prove to myself that the answer is right. The other big benefit to this is that those individual pieces– if it does turn out that there’s a mistake somewhere, you can individually debug, test, unit test those individual pieces. When there are problems, you’ll much more easily be able to find them. ► Subscribe to Our Channel Here: https://bit.ly/2TzgcOu Follow Us Here: Website: https://www.posit.co LinkedIn: https://www.linkedin.com/company/posit-software Twitter: https://twitter.com/posit_pbc To join future data science hangouts, add to your calendar here: pos.it/dsh (All are welcome!

Data Science Hangout featuring all of us! | Building up a data science team in a small org

Learning from our first open week, we decided we would continue to hold these open weeks once every 2 months or so and we were all the featured leaders for the week, asking questions to each other. There was a great discussion in the beginning of this week’s hangout on building up a data science team in a smaller organization. 3:53 George shared, “As the first data scientist in HR, I was tasked with starting from scratch with everything. So building out metrics, defining metrics, doing data governance, learning a new HR system, and then from there developing a team. So I think right now it’s just looking at the different tools that are out there, understanding how we might manage a data lake and trying to find the right tools. So far, my approach has been to have discussions with our HR managers - the primary stakeholders and the ones that are going to be leveraging the data - and communicating higher up or to the different managers within the organization. Also thinking about security because with HR data it’s highly secure information that we share. We don’t always want to share demographics, so also thinking about security policies. But just a lot of conversations with people about what their business needs are. 8:11 Eugene shared, “The first question is really what are going to be the highest impact projects and who would I hire as my first employee and then round out based on their weaknesses. But I would aim to try to cover these three bases: a programmer who understands production-level stuff, someone who understands the statistics side (probability distributions for example), and a contextual expert. If you’re really going to build a whole team of four or five, six people, you really need people who are, in my opinion, really good experts at each one of those three things, because it’s very rare to find somebody who’s an expert in all three. You’d be paying out a ton of money if you do find someone who’s an expert in all three.” 9:17, Libby shared that “In interviewing people or interviewing with people she finds that when they are building a team, they’re looking for somebody to hit the ground running. They always use that term: we need somebody to hit the ground running. A lot of times what I feel like they’re saying is we need somebody to do everything and we also need somebody to tell us what to do, because we don’t know what to do. That feels scary because I can’t be everything for everybody, but it also sounds like people are saying that person doesn’t really exist. My take on that is if you have somebody who does everything and knows everything, they are now your single point of failure. If they leave, all of your expertise goes in one person. Instead of needing to replace the one person who was maybe a subject matter expert, you now have nothing.” 10:52, Katherine shared, “I feel like a lot of times, looking for people who can ‘hit the ground running’ is corporate code for we are not going to onboard you or train you at all. When you are building a data science team, you need to say these are the people that I need and the skill sets that they’re going to have and then build your onboarding around what that team is going to look like. One of the things that we’ve been trying to get away from is, ‘oh, well this one person knows everything.’ For six months, all we did was write documentation about our processes and transcribe email chains from three years ago so that when we do bring on new people, we can onboard them not only on the technical aspect of the job, but also on the context of the data. This is especially important because we’re in the medical field, where you are bringing on people who may not have had any medical experience before.” At 12:06 Coulter shared, “I was in an org where data science was uncharted territory with everything done in Excel. I tried to get buy-in on this from a selfish point of view because I was dealing with all this data and I said, “This shouldn’t take this long. We’re spending a ton of time trying to do all this. Luckily, I had great leadership that said,”You know what, that’s right.” I was able to hire someone and immediately started converting everything to R to automate as many things as possible. The first time that we were able to show someone, hey, you know this thing that used to take you 16 hours, it takes 30 seconds now. And the joy in their faces– I will never forget that. I think that really showed leadership that this is something worth investing in even further. That was 2.5 years ago and now we are a team of 8.” ► Subscribe to Our Channel Here: https://bit.ly/2TzgcOu Follow Us Here: Website: https://www.posit.co LinkedIn: https://www.linkedin.com/company/posit-software Twitter: https://twitter.com/posit_pbc To join future data science hangouts, add to your calendar here: pos.it/dsh (All are welcome!

Matt Frazier @ Pie Insurance | Removing blockers for your team | Data Science Hangout

We were recently joined by Matt Frazier, Strategic Advisor and former Chief Analytics & Underwriting at Pie Insurance At 35:50 - Matt shared that being an effective leader is about being the person who makes sure that all of the conditions are set up, so that each and every one of their employees can succeed and can fully explore the domain of their competencies. Find smart people, and then set up the conditions, and get the heck out of the way. If there’s a blocker that is in their way, find a way to remove that blocker. Matt adds, “Now, are there performance reviews and things like that? Yeah, every company has them. I am a strong proponent against them. I think that performance reviews should be done every single day between the individuals that are working together. I don’t think it should be between a boss and that boss’s employees – I think it should be the individuals and their colleagues that are working together with one another. That’s where that feedback should be coming from. …I think that if we can create an egalitarian society where everyone is responsible to everyone else and everyone is giving constant feedback to everyone else on how to improve with empathy and with honesty, that is where you can create an organization or a social structure that actually allows everyone to win, and allows everyone to succeed.” On the topic of removing blockers, what should you do if you’ve identified certain roadblocks you need to get past? 38:12 - Whether it’s an I or a we…sometimes there’s a blocker for a whole team and sometimes there’s a blocker for an individual. I don’t know if any of you have taken any courses in nonviolent communication. I don’t believe all of it, but I think it is a toolset where you can sort of mix and match. Listen for needs and express needs. Start with, “I’m trying to do this for the company. I believe that this is going to be very valuable, do you agree?” You’ve got to get buy-in that what you’re trying to do is valuable for the company. In order to do that, I have certain needs that are not being met. This is what those needs are– it could be an individual, could be a group of individuals, a dynamic. It could be technology that isn’t there or budget. And then you really express that as a need. Not as so-and-so is doing something to me, and I’m mad. That’s a sort of selfish communication. What you want to do is you want to try to abstract that as much as you can. Now, you can’t always because sometimes there’s just a person who isn’t on board and so, you say, “Look, I really need this person to be on board, but I don’t think they are. And I want to ask you what we can do together in order to try and identify that other person’s needs and discover why it is that they appear to be a blocker. It may be in my own head, and I’m just in an echo chamber. But let’s have that conversation.” And if you don’t feel confident having that conversation yourself, go to someone who you think can have that conversation. It doesn’t have to be a manager, It could be a colleague who knows that person really well, and can set up that meeting so that you can have that meeting and identify what those needs are. There’s another book that I would really strongly recommend called Never Split The Difference by Chris Voss: https://www.blackswanltd.com/never-split-the-difference That book basically teaches you to talk to an individual, have a dialogue with them until you get to why they’re saying no to whatever thing you want to get through. Yeses that aren’t really yeses, don’t matter. Make sure you understand what the other person or organization’s needs are and then make sure that you’re constructing the right conversation, and having those conversations through an expression of needs on both sides. Usually, that is the Black Swan that will bust right through that blocker. ► Subscribe to Our Channel Here: https://bit.ly/2TzgcOu Follow Us Here: Website: https://www.posit.co LinkedIn: https://www.linkedin.com/company/posit-software Twitter: https://twitter.com/posit_pbc To join future data science hangouts, add to your calendar here: pos.it/dsh (All are welcome!

J j Allaire Jupyter Notebooks + Quarto for customizable and reproducible documents, websites and

To share our results and communicate effectively in data science, we need to weave together narrative text and code to produce elegantly formatted, interactive output. Not only does it need to look great, but it needs to be reproducible, accessible, easily editable, diffable, version controlled and output in a variety of formats, such as PDF, HTML and MS Word for convenience and often compliance. Jupyter has already made so much of this possible. By combining Jupyter with the open-source publishing platform, Quarto, built on Pandoc, you can easily create the output format and the styling that you need for any situation. With Quarto, you can author documents as plain text markdown or Jupyter notebooks with scientific markdown, including equations (LaTeX support!), citations, cross references, figure panels, callouts, advanced layouts, and more. You can also engage readers by adding interactive data exploration to your documents using Jupyter Widgets, htmlwidgets for R, Observable JS, and Shiny. In this talk, we’ll discuss authoring these dynamic, computational documents with Quarto and Python that bring code, output, and prose together, leveraging integrations with both Jupyter and the Quarto VS Code extension. Whether you’re new to Jupyter or have thousands of notebooks already, we’ll walk you through using a single source document to target multiple formats - transforming a simple document into a presentation, a scientific manuscript, a website, a blog, and a book in a variety of formats including HTML, PDF and MS Word. We’ll also show how you can change themes and styling, and publish these artifacts directly from the command line to the web, so they’re immediately available online

Brian Fannin @ CAS | Copy & paste is operationally dangerous | Data Science Hangout

We were recently joined by Brian Fannin, Research Actuary at Casualty Actuarial Society. During the hangout (38:46) with Brian, we spoke a bit about the areas where actuaries are turning to code-first data science. A big selling point for actuaries is when they find out they can replace a very typical actuarial and analytic workflow of creating a plot in Excel and copying and pasting it into Word. That’s operationally inefficient. It’s operationally dangerous. The notion that my entire analytics report is in one file: all of the code, all of the narrative, all of the tables, it’s like telling me that I can breathe underwater and fly. I think that as actuaries become aware of that capability, they will get happy about it as will the people who need to communicate with actuaries. Imagine you’re in a meeting and you have everyone looking at the same file and the plot didn’t update. “What do you mean we’re losing $1 billion a day?” “Oh, sorry, that’s yesterday’s graph. Today it is…” Resources shared during the hangout: R for Actuaries and Data Scientists: https://info.actexmadriver.com/r-for-actuaries Deep Learning with R (Second Edition): https://www.manning.com/books/deep-learning-with-r-second-edition The Theory That Would Not Die: https://yalebooks.yale.edu/book/9780300188226/the-theory-that-would-not-die/ CASDatasets: http://cas.uqam.ca/ R4DS Community: https://r4ds.io/join ► Subscribe to Our Channel Here: https://bit.ly/2TzgcOu Follow Us Here: Website: https://www.posit.co LinkedIn: https://www.linkedin.com/company/posit-software Twitter: https://twitter.com/posit_pbc To join future data science hangouts, add to your calendar here: pos.it/dsh (All are welcome!

Katherine Gerton @ Centene | Making sure you know other teams exist! | Data Science Hangout

We were recently joined by Katherine Gerton, Manager, Data Analytics & Reporting at Centene to chat about the power of embedded teams for bridging the distance between cool data science and meaningful business insights and bringing those teams together to create a community of practice that supports each other and the bottom line. During the conversation Katherine spoke about building tools that make your own life better, and then also spreading them to other people as a really valuable way to do work. Part of being successful in this is also making sure you know other teams exist! At 32:51, Katherine shares: There’s a lot of that community building and reaching out to people that I’ve incorporated into some of my leadership work – a lot of it is making sure you know that other teams exist. In an organization the size of Centene, this can be really difficult. For example: “Oh, I didn’t know that this team was doing this kind of thing with membership. I have a need to do something with membership. Let me make sure that I know who to reach out to.” That’s something that we’ve been really working hard on. In our internal R user group meetings – we’re highlighting different teams and what they are working on. “This is how we’re using the Centene tools.” It’s not always R but it’s just seeing how others are using our data to keep building those relationships. I think going back to something I said earlier, I did it for me. And then I’m more than happy that it’s also helping other people in Centene. How do you actually build those relationships? When you’re really close to a data project and there’s one piece that you don’t know - it’s might be shooting the email to the person that you saw last accessed that database because you can check those things. You can say, “Hey, I saw you were using this data. What’s going on with it?” Those kinds of small emails are important. It’s also getting over that hump of self-doubt, and thinking, “Oh, am I emailing the right person? Are they going to hate me for derailing their day for emailing the wrong person?” Just send an email because the worst thing that happens is that they don’t respond to you. And then you send an email to another person and build that out. As I’ve moved into a leadership role, it’s getting plugged in with other team leaders as well, where we now know the name of each other’s team and can say, “Do you have somebody on your team who knows about this or who can help with this?” That’s also something that the Women in STEM Group has helped with because women in STEM are across the entire organization. They are not just in corporate IT as your cloud engineers. Almost anyone with a data analyst title or anything like that could be in the STEM group. I’ve been exposed to so many more people and so many more incredible women at Centene through that other organization. It doesn’t just have to be the data science community where you are meeting all these other people across different parts of the company. __ ► Subscribe to Our Channel Here: https://bit.ly/2TzgcOu Follow Us Here: Website: https://www.posit.co LinkedIn: https://www.linkedin.com/company/posit-software Twitter: https://twitter.com/posit_pbc To join future data science hangouts, add to your calendar here: pos.it/dsh (All are welcome!

Why RStudio is now Posit (J.J. Allaire | Posit CEO) - KNN Ep. 158

Today, I had the pleasure of interviewing J.J. Allaire. J.J. is the founder of RStudio and the creator of the RStudio IDE. He is an author of several packages in the R Markdown publishing ecosystem including rmarkdown, flexdashboard, learnr, and distill, and also worked extensively on the R interfaces to Python, Spark, and TensorFlow. J.J. is now leading the Quarto project, which is a new Jupyter-based scientific and technical publishing system. In this episode, we learn about why RStudio has now repositioned itself as Posit, how it maximizes its open-source nature as a B Corp, and how J.J. as an open-source advocate views the private nature of many LLMs. I really enjoyed this conversation, and I hope you will as well!

Tracy Teal - It’s not just code: managing an open source project | PyData Seattle 2023

www.pydata.org An open source project starts with ideas and code, but it continues with people. We know that most open source projects rely on just one or two people for most of the work. And code is just a small part of these roles, which also include project management, conflict resolution, decision making in uncertain situations, building an inclusive community, and lots and lots of communication. Whether you’re just starting a project, interested in getting involved in open source, or already have a community of thousands, there are some tips, tricks and templates that you can use to make maintaining an open source project more manageable. PyData is an educational program of NumFOCUS, a 501(c)3 non-profit organization in the United States. PyData provides a forum for the international community of users and developers of data analysis tools to share ideas and learn from each other. The global PyData network promotes discussion of best practices, new approaches, and emerging technologies for data management, processing, analytics, and visualization. PyData communities approach data science using many languages, including (but not limited to) Python, Julia, and R. PyData conferences aim to be accessible and community-driven, with novice to advanced level presentations. PyData tutorials and talks bring attendees the latest project features along with cutting-edge use cases. 00:00 Welcome! 00:10 Help us add time stamps or captions to this video!

www.pydata.org Shiny is a web framework that is designed to let you create data dashboards, interactive visualizations, and workflow apps in pure Python or R. Shiny doesn’t require knowledge of HTML, CSS, and JavaScript, and lets you create data-centric applications in a fraction of the time and effort of traditional web stacks. Of course, Python already has several popular and high-quality options for creating data-centric web applications. So it’s fair to ask what Shiny can offer the Python community. In this talk, I will introduce Shiny for Python and answer that question. I’ll start with some basic demos that show how Shiny apps are constructed. Next, I’ll explain Transparent Reactive Programming (TRP), which is the animating concept behind Shiny, and the reason it occupies such an interesting place on the ease-vs-power tradeoff frontier. Finally, I’ll wrap up with additional demos that feature interesting functionality that is made trivial with TRP. This talk should be interesting to anyone who uses Python to analyze or visualize data, and does not require experience with Shiny or any other web frameworks.

Brad Weiner @ CU Boulder | Using data to influence institutional decisions | Data Science Hangout

We were recently joined by Brad Weiner, Chief Data Officer at University of Colorado Boulder to talk about the intersection of data science and higher ed. At 8:53 Brad shared an example where their data team influenced an institutional-level decision. Brad shares, “Doing the data work is the easier part, getting people to actually use the data and inform policies is much trickier. I always like to point to the fact that it really does take a village. We need all kinds of people to be invested and interested in a project.” One example we’ve been pointing to lately: We really want students to be successful. Not just because that’s our core mission but because we’re measured on that. All universities are measured on that in a lot of ways. Students want to go to a place where they’re going to be successful. Building a college degree really is a supply-chain problem. You need to have all of these constituent parts and they need to land at the right time. There’s tons of dependencies and those dependencies need to be built out years in advance. So if we don’t have enough chemistry labs, that student doesn’t get to take chemistry. If not enough students take chemistry, they don’t have the required courses and they can’t graduate. We’re constantly looking for these things. One of the things that we have found from the people in the bookstore is that students found the prices of their textbooks to be something of a barrier. We’re not only trying to graduate students, but we’re trying to graduate everybody as equitably as possible. If the experience is one way for some students and one way for another group of students, that is not considered success. What we were finding, and what we had heard, what we had learned, was that students were potentially choosing which courses to take based on the cost of the textbooks. Students of today are used to subscription services. Nobody ever thinks, how many songs did I listen to on Spotify? Am I getting my money’s worth there? They’re used to the Netflix models where you just pay one price and you get everything. It doesn’t matter how much you use it or how little you use it. We’re one of the first dozen or 15 schools that have gone in on this bookstore-equity access model, which is basically, students pay one price. This gives them the financial stability, predictability, and their ability to budget on books, but also the ability to be really flexible in what classes they take. By paying that one price, they get what we call day-one digital access. There’s evidence that having digital, immediate access to your books is actually a student success lever. So for a variety of reasons, we wanted to implement this program. One of the things that we were asked to do is figure out what price should the bundle be? Pricing is a really complicated problem - if the price is too high, nobody participates and the whole thing collapses on itself. And if it’s too low, you don’t cover your costs. We had a whole team of people who were thinking through that problem. We are happy to say that we used our super-sweet Posit Workbench set-up to simulate a whole bunch of different options. The Data Science team did that and we were able to guide them on what that price was. And it got deployed out. So next year, from what I understand, all undergraduates at CU Boulder will pay $279 a semester, and get all of their books on day one. If they drop a class, then those books go away and the new ones come in. ► Subscribe to Our Channel Here: https://bit.ly/2TzgcOu Follow Us Here: Website: https://www.posit.co LinkedIn: https://www.linkedin.com/company/posit-software Twitter: https://twitter.com/posit_pbc To join future data science hangouts, add to your calendar here: pos.it/dsh (All are welcome!

Natalia Andriychuk @ Pfizer | Hosting an internal data science hangout | Data Science Hangout

We were joined by Natalia Andriychuk, Statistical Data Scientist at Pfizer to discuss running an internal Data Science Hangout, building a supportive R community, discovering and learning new R packages/tools, and contributing to open-source initiatives. Resources shared: Rachael’s guide for hosting your own data science hangout: https://docs.google.com/document/d/1uKgLRacVyUJA1dH4f675dKP1gnbaw--QztxwIIiLAAA/edit?usp=sharing RTP useR Group: https://www.meetup.com/rtp-r-user-group/ Data Science Hangout LinkedIn Group: https://www.linkedin.com/groups/12610075/ Shiny app submitted to FDA Pilot: https://www.r-consortium.org/blog/2022/12/07/update-successful-r-based-package-submission-with-shiny-component-to-fda 56:41 - What’s something that you’ve learned from that process of starting your own internal data science hangout? Summarized from below: Start with a list of 10 or so people you’d like to invite Ask colleagues you have an established relationship with to be your first featured leaders Create a calendar of events that you can invite people to Use a form to collect the speaker’s bio, photo, etc. Schedule a 30 minute call with each featured leader the week before Try to plan out 3 sessions in advance Start inviting people:) Natalia’s response: It was a little bit overwhelming to think about how to start it but one thing you would need to start is a list of 10-15 people who you’d like to invite. First I would create the calendar of events. At Pfizer, we do our data science hangouts every other week. I specifically put the dates and send people an invitation asking them to be a part of hangout. I actually started the hangouts with Mike Smith and Douglas Robinson, who are part of our core team and are moving this initiative forward. For your first few hangouts, it can be easier to have colleagues join us as your co-host that you already have an established rapport with. I set up a Microsoft Form that I would send out: asking about: occupation, bio, certain questions they want me to ask, etc. I also ask them to provide their headshot. I think it makes the hangout invitation a little more colorful. For the featured leaders, I schedule a 30 min call with each guest the week prior to go over any questions that person might have if they never attended before. It helps me to know more about what they’re doing, especially if this is the first time I’m having a 1:1 with this colleague. I’m pretty new to the company as well, so we would chat a little bit about their interests - and then we have the hangout session. I’ll try to have at least 3 people booked in advance. So find your featured leader, and then start inviting people. Having an internal hangout has been very valuable because we are able to talk more about certain topics within our organization. For example, if I come to this hangout and we discuss certain topics, sometimes I might have to say, “Well, this is a great question, but I can’t talk about it because the information is proprietary.” With your internal hangout, you do not have to worry about that. This is how certain problems get solved faster. It also brings people together that wouldn’t work together necessarily. I think this is a very valuable part of it. ► Subscribe to Our Channel Here: https://bit.ly/2TzgcOu Follow Us Here: Website: https://www.posit.co LinkedIn: https://www.linkedin.com/company/posit-software Twitter: https://twitter.com/posit_pbc To join future data science hangouts, add to your calendar here: pos.it/dsh (All are welcome!

JD Williams @ Zoetis | 6-steps for POC to production & long-term value | Data Science Hangout

We were recently joined by J.D. Williams, Head of Business Insights and Analytics at Zoetis to discuss delivering significant business outcomes through data science solutions. Timestamps: 2:53 - Intro to Zoetis team 9:39 - Building a data science team from scratch 14:47 - Being flexible on location when hiring 17:02 - Promoting data science in the company 21:26 - Tips for building relationships with execs 23:13 - Example app showing their community growth 25:18 - Making an impact on manufacturing (where they use Posit tools the most today) 33:40 - Building up a data team at a startup 36:39 - Moving from proof of concept to production-ready apps (6-step process) 41:34 - Being open with the tools the team can use 47:22 - Designing requirements for data science and data analysts 52:50 - Keeping up with technology trends 6-step process for getting from Proof of Concept to Production & Long-Term Value. Identification/prioritization. For our manufacturing and supply chain leaders, we had a small steering committee of leaders and analytics leaders that came together to identify and prioritize the highest value use cases. Feasibility We took a little bit of time to gather the data and look at the data available (do we have enough data and the right kind of data to do a proof of concept? If so, we moved to next step. Proof of concept Here’s where we would build– we’re talking the ideal would be between two and four weeks – a quick proof of concept, using the data that we have sort of in a sandbox or offline. We’re not building production ready code, we’re not building something that’s ready to go live. We’re just trying to prove the value. Two things– can we do it and does it have value? If the answer to both of those is yes, there’s real business value and we’re successfully able to do it. Then we go to the fourth stage, which is the pilot. Pilot This is where we would make it more production ready. Here’s where we were going to partner with our data engineering team to take the analytic solution and put it into production on a small scale. And think of it as maybe one manufacturing site, where you’re not scaling it across many different places, but being more deliberate in how you’re doing it. This is kind of a risk based approach and we were given permission to fail. A lot of the proof of concepts succeeded, there were some that did not. Or some succeeded, but maybe didn’t have as much value as we anticipated. Focus on those highest value proof of concepts going on to the next stage of piloting. Scale up stage Those pilots that are successful, we want to scale that to other sites, other products, other stages of the process and leverage what we learn there and scale it across other areas. Sustaining How do we sustain the value long term? Those six stages are how we thought about it upfront. Within the first year or so of us getting started, the total number of use cases in our use case tracker was about 100 in various stages of those mentioned. Some were just ideas, some were being prioritized somewhere in the feasibility step, some of the proof of concept, et cetera. From there now, we’ve taken the most valuable of those and we’re actually focusing more on those and how we can highlight them and scale them. ► Subscribe to Our Channel Here: https://bit.ly/2TzgcOu Follow Us Here: Website: https://www.posit.co LinkedIn: https://www.linkedin.com/company/posit-software Twitter: https://twitter.com/posit_pbc To join future data science hangouts, add to your calendar here: pos.it/dsh (All are welcome!

Alix Schmidt & Amanda Ahrens @ Dow | Creating business value with community | Data Science Hangout

We were recently joined by Amanda Ahrens & Alix Schmidt from Dow Chemical to discuss designing enterprise data architecture to enable sustainability, how data science is really all about the people, and about leading a data science community of over 500 researchers at Dow. At 10:02 in the recording, Alix and Amanda shared that one of their executive leaders at Dow asked, “How can we use this community to start creating value for the company?” They suggested, why don’t you go figure out how to do a hackathon? That word can mean a lot of things to a lot of people but after really talking about it, we settled on this sort of Shark Tank- like the TV show Shark Tank - style thing where groups come up with a project idea and pitch it to this executive panel. How did you go from that one executive sponsor to a panel of eight executives in the first challenge? What really works is having the executive that’s already onboard sell it to the rest. It doesn’t work so much if you’re out there by yourself. If you can go along with that executive that’s already on board and explain the vision of why you want to do a Data Science Challenge or a Data Science Conference and what’s in it for them - it’s a lot easier to get them to say yes. They felt like it was an opportunity the other executive was giving them to really help set the data science direction for the company. In all three Data Science Challenges, winning projects were implemented in some way. Even if they weren’t funded directly initially, there was such high interest by the executives in moving forward with the idea. The number one project from last year actually just won an Edison Award, which is a big research and development in STEM award. That’s external recognition too! With that project, pieces of it were happening already, but a lot of value is created at the interface of different functions and different organizations in a company as big as Dow, which is like 37,000 employees. One of the things we encourage folks to do is network and get out there and find people in parts of the company that you wouldn’t normally talk to. That project brought three very small projects from our toxicology department, our molecular discovery research area, and our supply chain area together to make a really powerful tool for making safer and more sustainable products. That project is such an awesome example of exactly the vision of the event and to get that external recognition was really cool. A huge part of being able to bring people together across the company is making sure that you set a theme that resonates with the executives, but also, the mid-level managers because they have to be supportive of their employees actually participating in the Data Science Challenge. Our Shark Tank style challenge, wasn’t just a day or two days where people were working on a problem with the same data set. It was actually over a longer period of time. Beginning to end, the challenge was more around two months. There was a lot of time spent there, so people had to feel like it was worthwhile for their team. The first theme was more general - improving EBITDA. Then the second theme was around employee experience and customer experience. Then the last one that we did in 2022 was all around sustainability and so that really resonated with everybody. Everybody at Dow is trying to prove that they’re contributing to that, and that united a lot of people to come up with some great ideas cross-functionally. Did you come up with those themes with the executives– or the original executive sponsor? The latest theme was brought up to me by one of the technical principals at the company who thought it would be a really uniting theme. We pitched it to the executives that we knew were already on board and going to help us. They said, absolutely - let’s go forward with it. Dow seeks to be the most sustainable material science company in the world, and so that’s a very front and center theme for the company, not just the Data Science Challenge. So it’s pretty easy to get executives to rally around that. They were already interested in it, it was already on their scorecard, so might as well add this to help them achieve their goals. Finding themes that are enterprise-level for the whole company is really important, because we want to make sure the theme doesn’t exclude any one that has a certain type of job that just doesn’t touch that area. Executive sponsors tend to have goals at this company-wide level. ► Subscribe to Our Channel Here: https://bit.ly/2TzgcOu Follow Us Here: Website: https://www.posit.co LinkedIn: https://www.linkedin.com/company/posit-software Twitter: https://twitter.com/posit_pbc To join future data science hangouts, add to your calendar here: pos.it/dsh (All are welcome!

Carson Sievert: Towards the next generation of Shiny UI

About the talk: Shiny, the R package for creating interactive web graphics, recently celebrated its 10th birthday. Since then, Shiny has grown tremendously in many areas (e.g., performance, functionality, extensions, etc); however, a “hello world” Shiny app still looks like it did 10 years ago. This is mostly because Shiny goes to great lengths to ensure backwards compatibility; and as a result, default Shiny UI will likely continue to be based on Bootstrap 3 (a CSS styling framework released in 2010). However, thanks to the new bslib R package, it is now easy to opt-into a modern Bootstrap 5 foundation that “just works” with Shiny, R Markdown, flexdashboard, pkgdown, bookdown, and more. In addition to upgrading Shiny’s Bootstrap dependency, bslib also makes it much easier to do custom theming, leverage modern layout techniques, and create custom components (all from R without any CSS/HTML/JS required). At this point, bslib is still maturing, and does not yet provide what we’d consider a “complete UI toolkit”, but it should eventually replace and/or improve upon all of Shiny UI. In this talk, I’ll highlight bslib features that we’re most excited about (e.g., expandable cards, accordions, (sidebar) layouts, input controls, etc.), discuss some best design practices for improving user experience with these tools, and present some real world examples of these tools in action. Speakers’ bio: Carson is a software engineer on the Shiny team at Posit. He joined Posit in 2018, and in recent years, has focused primarily on Shiny for Python and improving Shiny UI. The Shiny UI work has manifested in the creation and development of many R packages such as bslib, thematic, htmltools, htmlwidgets, sass, shiny, rmarkdown, flexdashboard, and more. Carson also has a PhD in statistics, is a recipient of the ASA’s Chambers Statistical Software Award, has maintained the R package plotly since 2015, authored the book “Interactive data visualization with R, plotly, and shiny”, and ran a successful freelance consulting service for numerous years

Josh King @ The Knot Worldwide | Creating your data and analytics roadmap | Data Science Hangout

We were recently joined by Josh King, Director of Marketing Data Science & Analytics at The Knot Worldwide. At 36:28, we discussed: What goes into creating your data and analytics roadmap? I’m actually in the midst of this right now– as in the hour before this meeting. One of the things I like to come back to is from the CTO at my last company. He had this really good framework for thinking through this, and it’s to break it out into 4 things: Your mission Your vision Your maturity model Your strategy If you want to look it up, his name is Dave Kaplan and he has a great article on Medium: https://medium.com/policygenius-stories/missions-visions-maturity-models-strategies-ce5a4a408ab2 This gets into a good framework for building out and identifying the different aspects of a strategy that you should consider and having a clear alignment for what that will look like. Generally, a mission is like a single sentence for why your team or your department or your company exists. Your vision is what it means to succeed within that. So, if I’m thinking through marketing data science & analytics - I’m thinking what does it mean to have a best in class marketing data science organization across relevant brands? Your maturity model is, where are you along that map from very basic early foundational building into “I am best in class”? Then your strategy is how you get from where you are now to where you want to be in your vision. So, this really aligns a good framework for what it is that you’re building out. And to the other part of your question, does it cover all data work? I have data scientists and analytics that report into me, but there’s also some of a dotted line from all of our data engineers that focus on marketing problems so that can include BI, data operations, data warehouse, tracking architecture. As we’re thinking through a bit more holistically in terms of all of our data functions that are supporting marketing, I identify, what do we need to drive decision making for our marketing organization and not only how does data science and analytics fit into that, but what is the infrastructure we need from a data engineering perspective that would enable us to be able to do this work? Yes, it’s not necessarily my vision or my strategy that will get us there but working really closely with our Head of Data Platform so that my vision and his vision are really aligned together and we’re thinking through a bit more holistically as we’re building that out. How long is it? My current focus is on building out a 1 year, 3 year, and a 5 year roadmap to really have some intermediate stages along the way that we’re getting towards. ► Subscribe to Our Channel Here: https://bit.ly/2TzgcOu Follow Us Here: Website: https://www.posit.co LinkedIn: https://www.linkedin.com/company/posit-software Twitter: https://twitter.com/posit_pbc To join future data science hangouts, add to your calendar here: pos.it/dsh (All are welcome!

Sharing knowledge through writing is a critical aspect of scientific activity, including data science. It allows researchers to communicate their findings and insights to a wider audience, build upon existing work, and collaborate with others in their field. However, until recently, there have been limited options for publishing long-form writing and expository analyses authored in Jupyter Notebooks, a popular medium for data scientists. Enter Quarto - an innovative, open-source scientific and technical publishing system compatible with Jupyter Notebooks and other popular mediums. Quarto provides data scientists with a seamless way to publish their work in a high-quality format that is easily accessible and shareable. With Quarto, researchers can turn their Jupyter Notebooks into professional-looking publications in a variety of formats, including web pages, books, and slides. In this workshop, we will demonstrate how Quarto enables data scientists to turn their work products into professional, high-quality publications, websites, blog posts, and other shareable artifacts. As a bonus, we will also discuss how you can create and document Python packages using Jupyter notebooks and Quarto with the help of nbdev. The learning outcomes for the workshop include: • examine case studies where sharing scientific knowledge has greatly improved the efficacy of data science teams • author documents in plain text markdown or Jupyter notebooks with equations, citations, crossrefs, figure panels, callouts, and advanced layouts • learn how to author content in IPython/Jupyter and the Quarto VS Code extension • leverage Quarto for creating different types of publications, including personal blogs, knowledge management for teams, notes, books, websites, and presentation slides • extend Quarto with notebook filters and extensions • host websites and publications on platforms like GitHub Pages, QuartoPub, and Netlify • test notebooks and documentation with Quarto’s execution options • create and document Python packages with nbdev and Quarto

posit::conf(2023) Workshop: Tidy time series and forecasting in R

Register now: http://pos.it/conf Instructor: Rob J Hyndman Workshop Duration: 2-Day Workshop This course is for you if you: • already use the tidyverse packages in R such as dplyr, tidyr, tibble and ggplot2 • need to analyze large collections of related time series • would like to learn how to use some tidy tools for time series analysis including visualization, decomposition and forecasting It is common for organizations to collect huge amounts of data over time, and existing time series analysis tools are not always suitable to handle the scale, frequency and structure of the data collected. In this workshop, we will look at some packages and methods that have been developed to handle the analysis of large collections of time series. On day 1, we will look at the tsibble data structure for flexibly managing collections of related time series. We will look at how to do data wrangling, data visualizations and exploratory data analysis. We will explore feature-based methods to explore time series data in high dimensions. A similar feature-based approach can be used to identify anomalous time series within a collection of time series, or to cluster or classify time series. Primary packages for day 1 will be tsibble, lubridate and feasts (along with the tidyverse of course). Day 2 will be about forecasting. We will look at some classical time series models and how they are automated in the fable package, and we will explore the creation of ensemble forecasts and hybrid forecasts. Best practices for evaluating forecast accuracy will also be covered. Finally, we will look at forecast reconciliation, allowing millions of time series to be forecast in a relatively short time while accounting for constraints on how the series are related

posit::conf(2023) Workshop: Teaching Data Science Masterclass

Register now: http://pos.it/conf Instructor: Dr. Mine Çetinkaya-Rundel Workshop Duration: 1-Day Workshop This course is for you if you: • you want to learn / discuss curriculum, pedagogy, and computing infrastructure design for teaching data science with R and RStudio using the tidyverse and Quarto • you are interested in setting up your class in Posit Cloud • you want to integrate version control with git into your teaching and learn about tools and best practices for running your course on GitHub This masterclass is aimed primarily at participants teaching data science in an academic setting in semester-long courses, however much of the information and tooling we introduce is applicable for shorter teaching experiences like workshops and bootcamps as well. Basic knowledge of R is assumed and familiarity with the tidyverse and Git is preferred. There has been significant innovation in introductory statistics and data science courses to equip students with the statistical, computing, and communication skills needed for modern data analysis. Success in data science and statistics is dependent on the development of both analytical and computational skills, and the demand for educators who are proficient at teaching both these skills is growing. The goal of this masterclass is to equip educators with concrete information on content, workflows, and infrastructure for painlessly introducing modern computation with R and RStudio within a data science curriculum. In a nutshell, the day you’ll spend in this workshop will save you endless hours of solo work designing and setting up your course. Topics will cover teaching the tidyverse in 2023, highlighting updates to R for Data Science (2nd ed) and Data Science in a Box as well as present tooling options and workflows for reproducible authoring, computing infrastructure, version control, and collaboration. The workshop will be comprised of four modules: • Teaching data science with the tidyverse and Quarto • Teaching data science with Git and GitHub • Organizing, publishing, and sharing of course materials • Computing infrastructure for teaching data science Throughout each module we’ll shift between the student perspective and the instructor perspective. The activities and demos will be hands-on; attendees will also have the opportunity to exchange ideas and ask questions throughout the session. In addition to gaining technical knowledge, participants will engage in discussion around the decisions that go into developing a data science curriculum and choosing workflows and infrastructure that best support the curriculum and allow for scalability. We will also discuss best practices for configuring and deploying classroom infrastructures to support these tools

posit::conf(2023) Workshop: Steal like an Rtist: Creative Coding in R

Register now: http://pos.it/conf Instructors: Ijeamaka Anyene Fumagalli & Sharla Gelfand Workshop Duration: 1-Day Workshop This workshop is for you if you: • are comfortable with R and RStudio, experience with tidyverse and ggplot2 • are interested in applying data visualization skills more creatively, but may not know where to start or how to develop style/inspiration • are an artist interested in exploring code as another medium for creating their work R is a tool for data analysis but also can be used for self-expression. This workshop will be an introduction to creative coding in R in order to make visual art. We will take an inspiration-first approach, using compelling pieces to discuss and learn the techniques that shape the work. This workshop takes guidance from its namesake, the book “Steal Like An Artist” by Austin Kleon - once we have identified and learned to recreate existing works, we will cover how to take this inspiration and transform, remix, or reinterpret it in the pursuit of developing our own work and artistic styles. This workshop is hands-on and will cover color theory and manipulation, a reintroduction of the data frame as the foundation for creating art (instead of just for analyzing data!), using ggplot2 as an artistic canvas, creating basic and specialized shapes, tiling and pattern making, developing your own functions and using iteration. We will also discuss how to use controlled randomness to convert a standalone piece into a generative art system that can produce many distinct outputs. Creative coding may seem a world apart from data analysis, but we see a large overlap and intersection of the skills used in both, not to mention the creative muscles that are already used in data visualization

posit::conf(2023) Workshop: Fundamentals of Package Development

Register now: http://pos.it/conf Instructor: Andy Teucher Workshop Duration: 1-Day Workshop This workshop is for you if: • You have written several R scripts and find yourself wondering how to reuse or share the code you’ve written • You know how to write functions in R • You are looking for a way to take the next step in your R programming journey We will be demonstrating some workflows using Git and GitHub. Knowledge of these tools is not required, and you will absolutely be able to complete the workshop without them, but some of the lessons will be more rewarding to you if you are prepared to try them out. If you are looking to get started with Git and GitHub, we recommend you register for the “What they forgot to teach you about R” workshop on Day 1, and join us for this workshop on Day 2. We are often faced with the need to share our code with others, or find ourselves writing similar code over and over again across different projects. In R, the fundamental unit of reusable code is a package, containing helpful functions, documentation, and sometimes sample data. This workshop will teach you the fundamentals of package development in R, using tools and principles developed and used extensively by the tidyverse team - specifically the ‘devtools’ family of packages including usethis, testthat, and roxygen2. These packages and workflows help you focus on the contents of your package rather than the minutiae of package structure. You will learn the structure of a package, how to organize your code, and workflows to help you develop your package iteratively. You will learn how to write good documentation so that users can learn how to use your package, and how to use automated testing to ensure it is functioning the way you expect it to, now and into the future. You will also learn how to check your package for common problems, and how to distribute your package for others to use. This will be an interactive 1-day workshop, and we will be using the RStudio IDE to work through the materials, as it has been designed to work well with the development practices we will be featuring

posit::conf(2023) Workshop: Designing Data Visualizations to Successfully Tell a Story

Register now: http://pos.it/conf Instructor: Cédric Scherer Workshop Duration: 1-Day Workshop This course is for you if you: • want to understand and learn the art of communicating data with impactful visualizations • aim to improve your data visualization design to create effective and informative graphics • are willing to spend a bit more time to choose the right chart, proper color palettes, and suitable fonts along with additional elements to guide the viewer Communicating data through meaningful and easily accessible visualization is a critical competence for most data-related roles including data scientists, analysts, scientific researchers, and managers. A well-designed graphic is able to inform, spark engagement, explain patterns, and drive decisions and actions. At the same time, poor choices in the design process can complicate interpretation or even, intentionally or unintentionally, mislead the audience. The aim of this course is to demystify the creative processes of data visualization design to turn data into a meaningful story. Participants will learn helpful tips and tricks to create appealing and informative data visualizations that are not “just showing the numbers” but successfully tell a story. We will cover principles of good data visualization design, explore different options to display data, and discuss ways to guide and engage viewers with the aim to create impactful graphics. The course also features sessions on picking suitable yet beautiful colors, what to consider when choosing and pairing typefaces, and the layout of graphics, also in the context of dashboard building

posit::conf(2023) Workshop: Deploy and Maintain Models with vetiver

Register now: http://pos.it/conf Instructor: Julia Silge Workshop Duration: 1-Day Workshop This workshop is for you if you: • have intermediate R or Python knowledge (this will be a “choose your own adventure” workshop where you can work through the exercises in either R or Python) • can read data from CSV and other flat files, transform and reshape data, and make a wide variety of graphs • can fit a model to data with your modeling framework of choice We expect participants to have exposure to basic modeling and machine learning practice, but NOT expert familiarity with advanced ML or MLOps topics. Many data scientists understand what goes into training a machine learning or statistical model, but creating a strategy to deploy and maintain that model can be daunting. In this workshop, learn what MLOps (machine learning operations) is, what principles can be used to create a practical MLOps strategy, and what kinds of tasks and components are involved. We’ll use vetiver, a framework for MLOps tasks in Python and R, to version, deploy, and monitor the models you have trained and want to deploy and maintain in production reliably and efficiently

In both data science and academic research, prediction modeling is often not enough; to answer many questions, we need to approach them causally. In this workshop, we’ll teach the essential elements of answering causal questions in R through causal diagrams, and causal modeling techniques such as propensity scores and inverse probability weighting. We’ll also show that by distinguishing predictive models from causal models, we can better take advantage of both tools. You’ll be able to use the tools you already know–the tidyverse, regression models, and more–to answer the questions that are important to your work

If you want to develop a python web application you usually need to choose between simple, limited frameworks like Streamlit and more extensible frameworks like Dash. This can cause a lot of problems if you get started with a simple framework but then discover that you need to refactor your application to accommodate the next user request. Shiny for Python differs from other frameworks because it has tremendous range. You can build a small application in a few minutes with the confidence that the framework can handle much more complex problems. In this workshop we will go through the core limitations of Streamlit, and build a Shiny app which avoids those limitations.

Emily Riederer @ Capital One | Explicit design at the start of a project | Data Science Hangout

We were recently joined by Emily Riederer, Senior Manager - Customer Management Data Science & Analytics at Capital One. We discussed how a strong foundation in high quality data infrastructure and reproducible tools sets the stage for innovation in modeling, causal inference, and analytics, and so much more. Diving into a question asked at (42:38): What is your thought process for solving a problem that you don’t know how to solve immediately? One thing that I think is a really undervalued part of that process is thinking about how you will know a good solution when you find one? Also, how would you know if there was a good solution staring you in the face and you already had it? I think the more unstructured and complicated a problem can be, it can almost be a little deceptive of what’s good– which can have one or two bad outcomes. You find a good solution, but you don’t realize it’s good so you keep going You spend a lot of time chasing after an outcome, and only then do you realize, I solved the problem I was trying to solve but it wasn’t the problem I wanted to solve. Something I’ve really been experimenting with in my own work is having a lot more of an explicit design stage at the beginning of a project and thinking, how can you do a pilot? If I’m trying to predict some target, can I take those two values of that target and plug them into a downstream problem I actually thought that I was going to solve, and make sure that’s actually what I want to solve? Almost like frontloading model evaluation with even a fake solution is the first step versus last step. Then, I’ll check on one other point. I think the other aspect of that – going back to that level of abstraction – is figuring out how to take the context out of my problem to make it something more Googleable. So I mean thinking, not being like, “oh, this experiment, the random seeds were wrong, so I don’t have a control population - what do I do?” Backing that into more of a general question - “how do you sample a synthetic control through observational data?” which is something you can Google and then find a ton of resources about. I think pushing myself on what I want, and then finding the right framing at which to ask for help. ► Subscribe to Our Channel Here: https://bit.ly/2TzgcOu Follow Us Here: Website: https://www.posit.co LinkedIn: https://www.linkedin.com/company/posit-software Twitter: https://twitter.com/posit_pbc To join future data science hangouts, add to your calendar here: pos.it/dsh (All are welcome!

Natalie O’Shea @ BetterUp | Focus on relationships first | Data Science Hangout

We were recently joined by Natalie O’Shea, Analytics Consultant at BetterUp. In this hangout we discussed developing communities of belonging in data science, building a business case and so much more! (43:02) On building procedures and standards for your data science team: Focus on relationships first. Inevitably, what you define as the best practice in the first case, you’re not going to be doing that best practice in 6 months. Not always - there are certain things that will stay, and teaching your team to use Git branches and merge into main and those things are going to be pretty stable. But there are other more thorny questions that are really hard to build best practices around. For example, in our team, we support a lot of different organizations with different data analyses. Do we put everything into one big GitHub repo? Do we make a repo for every organization for every project? It’s always in development and it’s constantly iterating, so being comfortable with that is a key part of developing best practices, because it’s never going to be just like a set it and forget it. It’s going to be constantly in building relationships and those best practices together. We run an R users office hours every two weeks and I often don’t have an agenda or anything. It’s a great way to just first and foremost build community. But that’s also where people come to say, “I’m really struggling with this; how do you approach this?” And now we’re starting to build those best practices as we build out the whole Posit onboarding infrastructure. Our hope is that we have internal packages. I think building that into vignettes, like Confluence documents (I did see that Quarto is supporting Confluence documentation, which is awesome) Be comfortable with iterating and make sure that you’re always communicating with each other and building strong relationships. (52:06) On building a business case for data science tools: We did a survey of people in terms of how much time are people spending building a single slide deck? Where are all the places that you have to go? On average, you spend, say, 10 hours building this slide deck. Then hey, “if all of these data points were populated automatically for you, how much time would be remaining?” We used that and factored in people’s salaries and all of these things, and then came up with a rough estimate of the time-cost savings that building out this app would have. The app I’ve built now, I don’t think anyone would have been able to see that if I just started with that. Building MVP– minimally viable products - like little pieces of the pie is important. I started off doing parameterized reporting with R Markdown, and people were like, “That’s amazing!” But the problem is that people aren’t going to have the kind of flexibility on the end user side. So I’m like, “this is great - this is how we actually populate slide decks with data insights, but if you want the flexibility to change the branding, alter the wording, all of this stuff like, this is our next product.” Then you just kind of work your way up - where now I have a production-grade Shiny app that does all of this for you. Build in little chunks that get you there to your end result. ► Subscribe to Our Channel Here: https://bit.ly/2TzgcOu Follow Us Here: Website: https://www.posit.co LinkedIn: https://www.linkedin.com/company/posit-software Twitter: https://twitter.com/posit_pbc To join future data science hangouts, add to your calendar here: pos.it/dsh (All are welcome!

Oscar Baruffa @ IDH | Hiring for skills you don’t have | Data Science Hangout

We were joined by Oscar Baruffa, Senior Analytics Manager at IDH. We discussed the “soft skills” side of data science and how we manage ourselves, our teams and our projects - along with hiring. Specifically at 34:14, Oscar talked about the difference in hiring to replace you versus hiring for skills you don’t have. “When you’re getting into a management position, at some point you need to start hiring people and a team around you. Hiring is actually very different depending on different points in your career. I thought that it had been the same, because I had done hiring before, even when I wasn’t a manager. There comes this split that I think takes some people by surprise the first time. So before you’re, let’s say, a “manager manager”, if you are growing in your career and you do happen to be hiring someone, you are hiring someone most likely to replace you - like a more junior version of yourself. You’re going to train them and you are an expert of some level, and you’re going to bring them up to your level or something like that. You feel, I suppose, in a way, quite secure in what it is you’re doing because you’ve already got much more knowledge than them and you are bringing them up to your level. You feel very confident in answering the questions and mentoring them and all of that. But it becomes very different if you’re starting to hire for skills you don’t have. For example, I don’t have a stats background. I don’t have a data engineering background. I don’t have even that much, actually, of an analyst background. I was a market analyst, not a data analyst, per se. When you start hiring these team members into your team, these are for skills I don’t have. It becomes much more difficult for me to also assess - what are they good at or not? I first started - like I think most people start - trying to learn as much data engineering and data science as I could to try and just stay at least up with them. But there’s no way that you can do that. It clicks and you’re like, OK, wait, my job is not to be the expert of all of the people in my team. I am the facilitator of their work. If I know more than them, that’s probably actually a problem. We can’t have me spend 10% of time on all of these different vast fields while still being the expert in everything. That’s not going to be great and that’s quite a different switch. I think it takes a bit of getting used to - to start not understanding bits of what it is. Then the tables turn a little bit. I’m in some ways the non-technical manager of technical people, although I’m kind of technical myself. They’ll talk about things, and I also have to be like, whoa, whoa. Then I start also clicking a lot of what my directors and execs feel like sometimes. I’m like, yeah, you’re getting into way too much detail. I can’t do anything with what you’re telling me. My role mostly is to try and not just prioritize work but try and help them uncover where there’s work that needs to be done. Or if there’s a dilemma, try and break down, well, what if we go this direction? How bad will it be if this happens? Or how good will it be if this happens? Can we weigh risk like this? So I can convey to them as well where things just aren’t a priority. Because no matter what they do or stress about here, it isn’t going to matter later. That’s quite a different ballpark. I think it probably happens the first time you hire someone that’s not a replacement for you, it’s an addition to your team. It can catch you by surprise.” ► Subscribe to Our Channel Here: https://bit.ly/2TzgcOu Follow Us Here: Website: https://www.posit.co LinkedIn: https://www.linkedin.com/company/posit-software Twitter: https://twitter.com/posit_pbc To join future data science hangouts, add to your calendar here: pos.it/dsh (All are welcome!

Barret Schloerke: Lessons Learned Testing 2500+ Shiny Apps Every Day

About the Talk: The Shiny team tests 2500+ different combinations of Shiny Applications, R versions, and operating systems to verify no feature regressions occur within the bleeding edge of the Shiny-verse. Over the past few years, we have learned a few lessons to keep our tests robust and honest. There is a non-zero chance that a test failure is not your fault. When working with CI systems, external influences such as installation failures or slower computing power will prevent tests from executing properly. A picture is worth a thousand tests but visual testing is known to have a non-zero false-positive rate. To address this, we have utilized threshold based image comparisons for flaky tests. We have found that it is best to test the minimal amount of content where possible. Changes in App package dependencies can produce unintended changes in expected outputs. These hard learned lessons have reduced unreliable test results allowing the Shiny team to quickly respond to feature regressions. Speaker’s bio: Dr. Barret Schloerke is a Software Engineer at Posit. He currently develops and maintains many R packages in the Shiny ecosystem at RStudio including shiny, reactlog, plumber, learnr, leaflet, and shinyloadtest. Dr. Schloerke received his PhD in Statistics from Purdue University under the direction of Dr. Ryan Hafen and Dr. William Cleveland, specializing in Large Data Visualization

Leveraging Pins with Posit Connect

Leveraging Pins with Posit Connect Ryan Johnson, Data Science Advisor at Posit You might find this helpful if: You have reports that need to be regularly updated so you want to schedule them to run with the newest data each week You reuse data across multiple projects or pieces of content (Shiny app, Jupyter Notebooks, Quarto doc, etc.) You’ve chased a CSV through a series of email exchanges, or had to decide between data-final.csv and data-final-final.csv You haven’t heard of pins yet! For some workflows, a CSV file is the best choice for storing data. However, for the majority of cases, the data would do better if stored somewhere centrally accessible by multiple people where the latest version is always available. This is particularly true if that data is reused across multiple projects or pieces of content. With the pins package it’s easier than ever to have repeatable data. Timestamps: 0:17 - install the pins package and load into your environment 0:32 - register a board 0:59 - connecting to your Posit Connect instance from Posit Workbench or RStudio IDE 1:43 - define the Connect instance as your board 2:01 - pin the mtcars dataset to your Connect instance 2:38 - a pinned dataset on Posit Connect 2:50 - reading a pinned dataset Additional resources: Example workflow that involves Quarto, pins, plumber API, vetiver and shiny: machine-learning-pipeline-with-vetiver-and-quarto/ Connect User Guide - Pins for R: https://docs.posit.co/connect/user/pins/ Connect User Guide - Pins for Python: https://docs.posit.co/connect/user/python-pins/ 9 ways to use Posit Connect that you shouldn’t miss: https://posit.co/blog/9-ways-posit-connect/ Learn more: If you haven’t had a chance to try Posit Connect before or you’d like to learn how your team can better leverage pins, schedule a demo with our team to learn more! https://posit.co/schedule-a-call/?booking_calendar__c=RSC_Demo On the last Wednesday of every month, we host a Posit Team demo and Q&A session that is open to all.

Dan Negrey @ MarketBridge | Creating a framework for consistent measurement | Data Science Hangout

We were joined by Dan Negrey, Director, Analytics at MarketBridge. At (15:11) we asked Dan about a tip for impacting the business with data science. So I think every business is going to have KPIs (Key Performance Indicators), and there’s going to be other metrics besides KPIs, things that lead into that. As crazy as it sounds, some organizations struggle to measure those and to do so in a consistent and repeatable way. Maybe they measure something that just comes from one person sitting at a desk, and they’ve done it for six years, and they leave. All of a sudden, who knows how they do that? Creating a framework for consistent measurement is huge for an organization. The measurement is consistent and the outcomes are measured consistently. Then taking action to improve those outcomes can be thought of as more reliable because the measurement process is consistent. So that would be one thing for sure. Another – on that note, is decision making. Every company makes decisions. A lot of us are here because we like to do this kind of work, but most of our companies exist because they like to make money, and they like to grow. So we find a balance between doing what we do to help our company to achieve their goals. Find ways to help your company optimize cost, reduce waste and increase growth. All of that is through measuring and looking at decisions that have been made in the past and thinking about how they could have been made differently. This could be through historical analysis or building models to help make those decisions more effectively. That’s a huge win for any organization. There was also lot of love for repeatable data with the pins package at this Data Science Hangout. Dan Negrey shared: “Pins has been a huge package that we’ve started using a year or so ago…if you’ve never used pins, it’s definitely worth checking out.” Helpful resources on pins: Pins for R: http://pins.rstudio.com/ Pins for Python: https://lnkd.in/ghmxiEHV Great repo that uses pins: https://lnkd.in/ezvBkav Workflow that involves Quarto, pins, plumber API, vetiver and shiny: https://lnkd.in/e6gnMXfD Link to Ryan’s video & stepping stones: https://lnkd.in/erR-Mjr9 Other resources: MarketBridge career page (with open data science roles): https://marketbridge.applytojob.com/ ► Subscribe to Our Channel Here: https://bit.ly/2TzgcOu Follow Us Here: Website: https://www.posit.co LinkedIn: https://www.linkedin.com/company/posit-software Twitter: https://twitter.com/posit_pbc To join future data science hangouts, add to your calendar here: pos.it/dsh (All are welcome!

David Granjon & Bo Wang @ Novartis | User-friendly, self-serve tools | Data Science Hangout

We were recently joined by David Granjon and Bo Wang, Senior Data Science Experts at Novartis during the Appsilon Shiny Conference. We learned how their team designs production ready apps for clinical trials, from wireframing activities to automated deployments. How do you get feedback from users when you don’t hear from them directly? To know whether the applications are properly used, they use a tracker within Posit Connect. This is basically an application David developed using the Connect API. With the Connect API, he can see “who is accessing the application, which gives you some insights like which team is using it and how to target support.” If you develop an application for several teams, you can have some insight of which team is using the application the most. If you see one team is using the application 20 times more than another one, maybe you want to invest more people to provide two paths here. He supplemented this information by developing an R package, shinyHeatmap, to record in-app usage. “Each click is recorded to identify dead zones to refactor design,” he says. “If you have an app no one visits, maybe it’s poorly designed.” For more information on that Connect API: https://pkgs.rstudio.com/connectapi/ ► Subscribe to Our Channel Here: https://bit.ly/2TzgcOu Follow Us Here: Website: https://www.posit.co LinkedIn: https://www.linkedin.com/company/posit-software Twitter: https://twitter.com/posit_pbc To join future data science hangouts, add to your calendar here: pos.it/dsh (All are welcome!

Nick Pylypiw @ Cape Fear Collective | Building up trust with stakeholders | Data Science Hangout

We were joined by Nick Pylypiw, Chief Data Officer at Cape Fear Collective. Nick shared that one thing he’s been successful at in his career is building up trust with stakeholders. How do you build that trust? First off, people like data and analytics if it confirms their preconceived biases and beliefs A lot of people are fans of analytics and data science if it’s confirming what they already believe. One of the things working in pricing and marketing analytics at Lowe’s, is if I went into a room with a bunch of people who are marketing lumber and I said, “Hey, the promotion that you did last week did really well.” They may think, yeah, we really like this guy. If I said, “Hey, but it missed these markets and these markets” …if it counters their beliefs then that’s where they start poking holes and wanting to find fault in it. Find some quick wins. What are some small projects we can work on together that are low stakes projects that get people to buy into it and see, “Ok, now I can see why there’s value in this way of thinking.” When that inevitable cognitive dissonance comes, then you’ve built up some trust and some capital with that partner. There has to be a boots on the ground connection. For the same reasons we talked about building trust and capital in a Fortune 500 company, if you think about the state in that same way, if you’re from the beach town and you try to go up into the mountains and tell them what they don’t know about their public health crises, you’re going to get run out of there. You still have to build these connections organically. The same way we talk about building capital in a big company - especially with this line of work, you’d be surprised at how much buy-in you can get if you show up and you actually know how to pronounce the town name and the county name correctly. Do you go into Beaufort, North Carolina and you say “Buford”. That’s South Carolina by the way. Spelled exactly the same, Beaufort in South Carolina and Beaufort in North Carolina. If you pronounce it the other way, you’ve lost them before even the first slides hit the screen because it’s just some outsider coming in here who knows nothing about us. Learn about their area (of work) One of the things that our data science team has done is when you’re learning about a new area, one of the first tasks that we start doing is putting together a deck of the five worst areas of poverty in this area. I want to know the five areas where there’s great employment parity or great unemployment rates, all these different things. Through that exploration, you understand, oh, there’s this town here and there’s this county and you learn about that area. So now when you are in a conversation, you can intelligently talk about that region. It doesn’t sound like you’re just some person looking at a chart and saying, you need to do this and this. ► Subscribe to Our Channel Here: https://bit.ly/2TzgcOu Follow Us Here: Website: https://www.posit.co LinkedIn: https://www.linkedin.com/company/posit-software Twitter: https://twitter.com/posit_pbc To join future data science hangouts, add to your calendar here: pos.it/dsh (All are welcome!

Dara Straussman @ Stripe | Partnership-model when forecasting | Data Science Hangout

We were joined by Data Straussman, Data Science Manager at Stripe. Dara’s team focuses on forecasting, machine learning, and analytics in the Finance and Operations spaces. We were able to get a glimpse into their financial modeling methodology at Stripe after a question from Alan at 12:59 Question: How do you get buy-in from business stakeholders who historically would have been setting targets (like salespeople and their leaders) that the forecasting you’re doing seems like a realistic enough picture of the world? Answer: It’s an ongoing evolution for how we do this interaction because it’s very important to get the input from stakeholders. There might be a big sales deal coming down the pipeline that no statistical model will know about. There might be some product launch plans that we’re just not going to be able to learn from history. So we find that interaction very important. When we started doing the – we call it the statistical forecasting and the adjustments — it was all done in spreadsheets by finance folks. We did really have to prove our value and show how a statistical model will actually help. So our current system: We have the statistical model that’s all done by data science. We do backtesting and reports to be able to build confidence in each level of the hierarchy so that people can understand where do they expect accuracy, where do they expect less accuracy. We have a whole process with the finance and strategy team, where they make adjustments to the forecast and are pretty clear about where they are doing adjustments and how it’s affecting the total. Then we track both - the statistical versus the adjusted forecast. What we’ve learned over time is that making adjustments in certain ways or certain places is very important and very effective. We sort of encouraged the finance and strategy team to focus their efforts there. Whereas in other places, the statistical model is quite accurate, and it’s best to spend effort elsewhere. So that’s the baseline of how we think about it– again, ever evolving. We also have an embedded model so we sit with finance and strategy. We work really closely with them and really understand their problems. It’s very much a partnership-type model rather than a “throw a model over the wall” type model. ► Subscribe to Our Channel Here: https://bit.ly/2TzgcOu Follow Us Here: Website: https://www.posit.co LinkedIn: https://www.linkedin.com/company/posit-software Twitter: https://twitter.com/posit_pbc To join future data science hangouts, add to your calendar here: pos.it/dsh (All are welcome!

Art Steinmetz, (formerly) @ Oppenheimer Funds | Communicating with Execs | Data Science Hangout

We were joined by Art Steinmetz, private investor and former Chairman, CEO and President of OppenheimerFunds. During our conversation, Art shared his perspective on open source data science and how these tools helped contribute to the company’s bottom line. He also shared a few tips on communicating with executives - from an executive’s point of view, included below: Two key points (20:31) Data visualization is the most powerful way to get a narrative across quickly. Don’t use a PowerPoint presentation when you should be using a memo that people can read in a narrative On point one: Spend time learning good visualization techniques. Even if you’re a math whiz and a coding whiz, understand good visualization. It’s an aesthetic issue. It’s an art. There’s lots of blogs, lots of literature that talk about good visualization and bad visualization. For example: Don’t use a linear scale when you should be using a log scale, simple stuff like that because I’ve seen so many bad charts. At best, you’re going to lose your audience quickly. At worst, your audience will draw the wrong conclusions and make bad decisions. One point two: The physicist Richard Feynman was on the Challenger disaster panel. One of the big takeaways in that inquiry was shortcomings of PowerPoint for technical work.. So the other point I would make is, don’t use a PowerPoint presentation when you should be using a memo that people can read in a narrative. All of you are familiar with the problem of seeing a PowerPoint slide. You’ve got landscape orientation and you’ve got this incredible amount of 12 point text filling up a slide. Sometimes you’re subjected to sitting in a conference room, having that thing with 2 minutes worth of text on a slide that you’re supposed to process. Of course, nobody looks at that at all as they’re listening to, hopefully, what the speaker is saying. It’s a complete waste of everyone’s time to create and display this giant PowerPoint, this massive quantity of text on a PowerPoint slide. So don’t use PowerPoint when a pre-read memo would do the job. And yeah, some people aren’t going to read the memo. But treat your audience with respect anyway and tell them you’re going to assume people have read the materials. Then if you’re going to have a PowerPoint or a slide deck: have three, four bullet points at most on a slide with compelling visualizations that tell your story. That’s going to earn you far more respect than showing that you’ve crammed your PowerPoint with a million words. Example of Shiny generating discussions and helping investors: (37:30) So for instance, at Invesco right now– one of their folks has created a Shiny app that if one of our customers (our brokers) shares their customer’s (end investor) portfolios with us - we can run an analysis on that to help them optimize their tax situation– when they should take capital gains, when they should take capital losses, what they should sell to realize a loss or a gain. Then if they want to keep the portfolio complexion the same, what should they then buy on the other side to keep the portfolio complexion– the overall risk or aggressiveness - the same. He built a Shiny app that does that. All of the Invesco salespeople can look at all of the advisors that they serve (in that Shiny app) and that generates discussions. Salespeople love to have opportunities to call their customers up and have an interesting discussion. To say, “look, here’s an issue you have that I think I can help you solve.” Then if the discussion goes further, with one click, they generate a detailed PDF report on exactly what the gains and losses are across the portfolio. And the salespeople just love that tool. ► Subscribe to Our Channel Here: https://bit.ly/2TzgcOu Follow Us Here: Website: https://www.posit.co LinkedIn: https://www.linkedin.com/company/posit-software Twitter: https://twitter.com/posit_pbc To join future data science hangouts, add to your calendar here: pos.it/dsh (All are welcome!

Data Science Hangout | Regis James, Regeneron | Achieving scalability & showing value of community

We were joined by Regis James, Senior Manager (Biopharmaceutical Data Science) at Regeneron Pharmaceuticals. Achieving scalability through standardization (19:04) In order to achieve scalability I do have to standardize things a bit. We use Confluence, so on the wiki that I’ve made, I have a lockdown page where I have some standardized messages that I send out to people at different phases of things. I do customize and read what people say about themselves and I’m thinking, “this could be useful here, that could be useful there.” One of the things that I do is– I have this whole ingestion pipeline that I maintain to identify new members of the community and who can help the community learn more about the blockers to current responsibilities they have for their job. All companies have a directory where you can learn about who exists at the company and see people’s job titles. I can look into the directory for data or data science or whatever and see if the people that come out in the results are already in my Microsoft Teams group because they could be potential new people who could benefit from being in the community. They might be able to do their job better and also help other people do their job better, if they can connect to others who have similar needs or can offer similar things. I do this on a semi-regular basis, so I can really help onboard people who have just joined the company or maybe moved into a data science type role. Then I reach out to these people, and use my standardized message like, “Hey, I just want you to know this group exists. This community was built just for people like you. This is what we do and here’s a link to the wiki that has the links of all the recordings” - because we have a growing library of all the conversations just like the Hangouts. I only send one email and ask people to let me know if they’re interested in it. I don’t spam people. Of the subset, who answer - sometimes it’s like 20% that respond, they say, “Yes, this is amazing. Thank you for letting me know. I just came to the company. I didn’t even know if there was a community.” I’m also doing it from my own perspective of when I joined the company. When they respond and then they say they’re interested, I add them to the Teams group, to the Active Directory group, and then forward the invitation to the ongoing gatherings every other Friday. In the invitation text I paste in, “Welcome to the group. Please introduce yourself in the introduction section" and include a link that takes them directly into not just the Team for the group, but the channel of introductions. Since doing this, I’ve gotten a lot higher percentage of people who have been added to the group to start introducing themselves and say what they work on. I see what people are working on, and integrate that with my understanding of what people need help with from the Shiny app (the poll for what talks people are interested in.) Then I reach out to them and say, “Hey, would you be interested in being one of the guests for an upcoming event?” I send them the link and they can see there’s no pressure because I’m a year out. I’ve got someone every other week. So it’s like, Hey, would this be something you’re interested in and then I am gently having a conversation over time. Sometimes people drop out and I just reach out to those people and ask if they would be able to switch. How do you show the value of community? (40:14) To prove the contribution, the benefit of a community – I use the words stuck and unstuck because that’s really the only thing the business, or any organization cares about. There’s a bunch of stuff that the organization has to do. There are obstacles in the way, they are stuck. How do they get unstuck? That’s what data science is for, really. You can argue that it’s also for going from stuck to unstuck. The non-computational people who have the power to bestow upon you promotions, more money, or more influence over the company to make other decisions, really care about the value of the institution. If you can show how the existence of that community propagates through the network that exists in the institution so that something goes from stuck to unstuck and you can mark that, you can measure it, then you can say this only happened because of me. If you’re a community that’s gathered around pulling thorns out of your colleagues arms, you can say, we pulled 15 thorns out or we taught another group how to pull 100 thorns out because we were force multipliers. If you say, “what do you hate about your job?" to the person with power that I need to prove the community’s value to, think about how you’re reducing those pain points for those people and enabling them to go from stuck to unstuck. Collect those things and showcase them. From the get go, you should be thinking about how to indicate success to leadership. To join future hangouts: pos.it/dsh (All are welcome!

Data Science Hangout | Namrata Shetty-Anderson, UPS Store | Professional development for data teams

We were joined by Namrata Shetty-Anderson, Advanced Analytics Manager at The UPS Store. Right from the beginning of the conversation with Namrata, we dove into the art of data storytelling (7:20) …In my mind, data science is as much a science as it is an art. To be able to tell your story, you could write hundreds of lines of code and you could build amazing models, but at the end of the day if you can’t translate it to a non-data person as a data story, all that is a waste. You’re not adding any value. Businesses don’t care about your code. My boss doesn’t care about my hundreds of lines of code. He wants value. So I call it the art of data stories. I actually took a course by Kevin Hartman from Google, which talks about this. One thing I learned from that course is that you want to start with a solution for the problem in a tool agnostic environment. Don’t start with your tool when the problem is posed in front of you because what happens is the tool is going to limit your ability to tell your story. If I say I’m going to use Power BI, then I’m going to be limited to the visuals that are available in Power BI. So what I started doing, literally, was use a blank page and a pen. What do I want my outcome to look like? Once I know what that story is going to look like on a blank sheet of paper, then I decide what tool I’m going to use. Now the tool is going to depend on a few things: How quickly do I need to turn this around? How complex is this task? How good am I with this tool? Those are the things you need to look at. People say, Python’s better than R, R is better than Python. No, Power BI is the way to go. Tableau is the way to go. No, everybody’s right and everybody is wrong. Your tool of choice will depend on the problem you’re trying to solve. Don’t fall in love with anything you’re doing. Today you’re doing it one way, you’re going to find a better way to do it as you keep learning. *The course mentioned above was Business Analytics, Communicating With Data by Kevin Hartman: https://www.coursera.org/learn/intro-business-analytics &/or https://elvtr.com/course/storytelling-with-data Namrata also shared thoughts on approaches to professional development and skill building - (22:58) Managing a data science team is different from managing a team that’s operations driven, product driven, or even a software engineering team. It’s different because problems that come to a data science team are not always well defined and the solution is not cookie cutter. There’s no right answer, there’s no wrong answer. You need a research oriented approach to what we do and a drive to keep learning. So here’s what we have been doing. My whole team has the option of picking their learning platform. Some pick Coursera, some pick a virtual summit or buy a book, whatever. You tell me what your best learning approach is and you can have it. The team is also encouraged to block off time on your calendar. X hours a week or X hours a month, whatever you like to focus on learning and put it on your calendar. No one’s going to bother you. Do we do it? Sometimes. They’ll block it off and sometimes won’t do it. It happens to the best of us. We have a week long group camp Every year we have kind of a week long group camp, as I call it, where we bring in a certified instructor (we’ve been focusing on R for the last two years at least) and just work on little projects with the team. For this week, the team is not bothered by anyone just to focus on learning. (more on how they block that time at 31:51) We started having monthly sessions. We started with best practice sessions where one of the team members would say, hey look, this is a project I worked on and here’s how I approach the problem. This helps someone that’s new on the team, someone that’s learning to get some exposure to it. You can learn everything online, you can learn from instructors but then when you have to apply it in the real world, it’s not a one to one translation. Real world data is not normally distributed. Real world data has noise in it. When we maxed out our best practice sessions, we started doing a micro assignment. My team member Liz puts together micro assignments for the team with real work data - like online reviews, customer data, sales data - and perform these operations in R. We put together a central repository Because my team does so many things, we have a repository where we have reference guides, best practices, and a lot of documentation. If someone new joins my team, I tell them you’re going to spend your first week just reading everything that’s on that repository. Documentation, process documentation plays a very important role and it allows us to cover for each other. We want to rely on processes that make our people’s lives easier.

Data Science Hangout | Emi Zambada, Nationwide Financial | Building a story for the C-suite

We were joined by Emi Zambada, Assistant Vice President, Annuity Distribution Intelligence at Nationwide Financial. In talking with Emi about data science in insurance technology and managing teams through digital transformations, we also learned more about building a story for the C-suite in our own organizations. (40:26) Storytelling is critical. I go back to thinking about how we speak to little kids. You need to speak their language. They are not going to speak your language. If you spoke in Shakespearean language to a kid, they’re not going to understand you and they don’t care. You’re going to lose them. Listen to your leaders. Listen to the earning calls or whatever ways that they present to the organization. Pay attention to the words they use. Pay attention to how they describe things and the metrics they share. Use the words they use. Words are important. You can say the same thing with different words. We talk about data foundation, but if you say data integrity - you might say, well data integrity and data foundation are the same. If they use the word data foundation, use that. Use their words so they can understand you. Keep it consistent. Think about the old times - and the old fashioned newspaper. The New York Times always looks the same. They have the same structure, the same format. The articles and the layout are similar every day. Imagine if they tweak things and move things around - you will spend a lot of energy and time trying to figure it out. It takes mental energy to figure out the format and the structure that you don’t care about. You want to read the news. All your energy is to understand the content of the news. The same thing with storytelling and dashboards. Find a way to use the words, the structure, and the metrics that they use and are familiar with so that they don’t spend time and energy trying to understand your dashboard - your story. For example: the metric that you’re tracking is going this way, we might need to take action on this. Be very specific. Don’t say a lot of things. Less is better. Be clear, concise, and very specific on the things that you really care about. Repeat the things you care about. Silence doesn’t mean they agree. Watch them, look at their expressions and repeat. A mistake that we can make is that we don’t recap what we talked about last month. You can’t walk into a meeting thinking that they remember everything that happened last month. They don’t. They have done so many things since then. Don’t feel offended, it’s normal. Go back to that and say, last time we spoke we did this. Now we’re going to do this and let’s bring it to the present. Speaker bio: Emi leads strategic business intelligence for Nationwide Annuity distribution by leveraging data, analytics and technology and partnering with senior leadership to identify trends and measure efficiency and effectiveness of distribution. Emi is recognized as a thought leader and was recognized by MIT Chief Data Officer Magazine´s “40 Under Forty Data Leaders in 2022” and is a recipient of the Hispanic Association on Corporate Responsibility’s “2022 Young Hispanic Corporate Achievers Award”.

Data Science Hangout | Yu Cao, Exeter Finance | Impacting business with data science

We were joined by Yu Cao, VP Data Science at Exeter Finance. Speaker bio: Data science professional, EMBA student, amateur biologist, rock’n’roll zealot. Not only viewing business problems from the perspective of data science, but also from the perspective of the business. Yu shared his thoughts on creativity as a data scientist, working with the business, growing in your career, and much more. A few snippets from our conversation on building relationships with the business. (15:32) It all started with networking. I work with a very analytical team, so a lot of the people there just want to code and build a fantastic model, not spend time networking with people from other business lines. But actually, this is not the right attitude. If you want to collaborate with other people, first you need to get to know them. You need to understand their business – and you need to become their friends. Usually I reach out to them and do a self-introduction to let them know what I do and what my team can do. Let’s go out for lunch, let’s grab a cup of coffee and talk for 15 minutes to see what kind of business difficulties you are having now. If you are a sales team, are you worrying about how to increase the volume of sales? If you are a loan origination team, are you worried about how to increase the capture rate? Let’s talk about that. Then I will see, how can I connect my data set knowledge with the problem you are facing now? I can see whether I can build a model to help you solve that problem you have. Usually, the collaboration starts with this. If you want to build a data science team from scratch (25:51): Figure out what your team can do for the business. If data science has little to do for the business, it will create very little value there and it doesn’t make sense for you to build a team. You probably need to go to a new company. If you determine that data science can provide value to the business, you need to do some public relations. You need to let everybody, all the leaders in the company, know and understand this. Reach out to the leaders in your organization and ask them to provide feedback for your work. Tell them “My goal is to build a data science team and become a data science leader in this company. What do I need to do to make this happen?” Everything starts from the people, the buy-in from other leaders. If you are a data scientist wanting to move into leadership, you need to show ambition to leadership. The job market for data science is hard. This is the right time for you to show the company that you want to invest in yourself - that you don’t want to just code and build models, but also increase your influence, learn more about the whole business, and contribute to the entire organization. ► Subscribe to Our Channel Here: https://bit.ly/2TzgcOu Follow Us Here: Website: https://www.posit.co LinkedIn: https://www.linkedin.com/company/posit-software Twitter: https://twitter.com/posit_pbc To join future data science hangouts, add to your calendar here: pos.it/dsh (All are welcome!

Data Science Hangout | Satish Murthy, Janssen | Creating a validated environment for reproducibility

We were recently joined by Satish J. Murthy, Senior Manager, Pharma R&D IT at Janssen. During the hangout we dove into the topic of validation and what it actually means to have a validated environment. Snippets from our conversation with Satish: In regulated industries like pharma and finance, any time a health reporting agency comes in and asks for proof, we have to be comfortable in saying that what we ran a couple of days ago, weeks ago, months ago, or years ago – we need to be in a position to replicate that entire environment as is. So this goes through a formal validation/verification process. And this, in traditional parlance, is known as a GXP platform. [GxP is a general abbreviation for the “good practice” quality guidelines and regulations.] X will stand for clinical practice, manufacturing practice, lab practice, etc. So the verification validated environment is often referred to as a GxP environment. It is to build confidence for the end users that we serve in pharma. It is for folks who want to help deliver patient care, which is crucial. One of the key components of this is containerization. Because the ask in validation is to ensure repeatability and reproducibility, the only logical choice at this time is containers. We have to containerize. I have a responsibility for the R part of it so I’m going to concentrate a little bit more on that. First: Users would want to basically run through their studies using R. We are using the Posit Workbench as our launch pad. This is deployed on a traditional EC2 instance. This is a production platform but there is a logical grouping where our users would first want to come and test it in a development area, and then move it into the traditional QA and prod. The way they would first test in the development area is, number one, the entire Posit Workbench is containerized. We always try to keep up with the latest release of Posit. There are some unique challenges around it - mostly about the IQOQ, and the time that it takes. It’s not just Posit, there are other vendors [like Atorus] who are helping us with this effort. We have to go through a formal process of vetting, validating, and verifying. So all of this takes time. That’s one challenge that we have. Second: Because we have containerized, it gives our users the capability to test something that is locked down and be ensured that, again, from a repeatability perspective, containers are the only way that will help them with that. So first, we will go through defining the process and specifying the requirements as to what really needs to go into the container. For example, if our users have identified a set of workflows that they would want to help them with the clinical studies that they are looking into. Traditionally, it will map to a set of R packages - the packages that need to make it into this container. This is where we are using standard technologies and tools that are used in the industry. We have a Jenkins pipeline and we are using the Posit Package Manager to lock down versions of our packages that we want to go into the container. There are some business processes that are defined as to what should go into this container. Once we have defined, we run through the build process to create the container and we will verify it in the traditional Posit Workbench. Once our users are comfortable that, yes, this is the workflow, this fits our model and we don’t see any issues, that container is then locked. Then it moves into the QA/Prod area and that is what is deemed as a validated run. Anything that the users would try out in their development environment is a prerequisite, but it is not deemed as a validated run. It is only when it is run through the production that it is deemed as validated. In order to do that, all of these validated runs behind the scenes will run as a service account user. Behind the scenes, we also have the traditional EKS cluster where we scale up and launch these containers. _ Thank you to the Atorus team for their help in planning today’s session!

Justin Elszasz @ City of Baltimore | Data governance to better serve citizens | Data Science Hangout

We were joined by Justin Elszasz, Chief Data Officer at the City of Baltimore. Justin shared about the collaboration happening among other US governmental data organizations and Michael Bloomberg’s theory of change that if you really want to make an impact on people’s lives, local government is the place to be. At the Federal level, you’ve got a very wide, broad impact but it is very hard to see this trillion dollar budget trickle down to see how it impacts someone’s lives. Local government is where that money eventually comes into your programs and projects. Justin shared two organizations he is involved in: Bloomberg Philanthropies City Data Alliance: https://lnkd.in/en_-f4nS Civic Analytics Network: https://lnkd.in/e2imBP3k As a group, we also shared portals for public data across various cities: ⬢ Baltimore: https://lnkd.in/eGm_AKZd ⬢ San Francisco: https://lnkd.in/e66UeK2w ⬢ LA: https://data.lacity.org/ ⬢ Chicago: https://lnkd.in/eMHpdb3P ⬢ Washington, DC: https://opendata.dc.gov/ ⬢ Toronto: https://open.toronto.ca/ ⬢ Ottawa: https://lnkd.in/e8yhMzMk Part of the hangout touched upon legacy systems in government and the City of Baltimore’s direction in regards to hardware and cloud infrastructure. Justin shared that: Chief Data Officer roles run the spectrum in terms of responsibilities, and where they are situated organizationally. I have a little bit less control over architecture. That said, yes there are tons of legacy applications and infrastructure to deal with. Luckily, like we have an IT department that’s on it right now, and has plans to mitigate a lot of that. As those things get replaced, we will only go up in terms of data quality. Just over the last 2 years, we have rolled out Workday as our new ERP (enterprise resource planning) system. That in and of itself, has addressed a lot of Finance and HR data quality issues. We’re making moves in that direction. Yes, there’s legacy systems but I challenge you to find a Chief Data Officer in another city who doesn’t reckon with that sometimes. As far as cloud goes, our GIS team is working hard on moving a lot of our GIS layers and infrastructure over to cloud with Esri - as well as our Baltimore open data platform. I think it’s picking your battles and where you’re going to get the most bang for the buck at the moment for us. I’m looking to pilot a couple of tools to move to the cloud. One example I’ll mention is that over the summer, we partnered with a group at Carnegie Mellon called Data Science for Social Good. You may know this already, but Baltimore has a lot of vacant buildings and when a building sits vacant for long enough, rooftops tend to become an issue. Back in January of last year, we had 3 firefighters killed when a rooftop was in a fully involved fire. We partnered with Carnegie Mellon to develop an AI tool that will detect collapsed roofs based on our aerial flyover imagery. Every year we get new flyover imagery, which means every year we’ll want to refine and update the model and get new predictions, so we can find any new buildings that might have rooftop issues. We can’t run that on someone’s local machine, so that’s a good opportunity to start pushing the bounds of what we can do and moving to the cloud. We’re looking for a couple of places to definitely move that way. Other resources shared in the chat: ⬢ An article on Data Engineers before Data Scientists by Keith McNulty: https://lnkd.in/evTpT7ee ⬢ A citizen data science analysis of Baltimore Waterbill system: https://lnkd.in/eXGm6Ek4 ⬢ Book recommendation - “Change: How to Make Big Things Happen”: https://lnkd.in/eVH4NHSC We were joined by Justin Elszasz, Chief Data Officer at the City of Baltimore. ► Subscribe to Our Channel Here: https://bit.ly/2TzgcOu Follow Us Here: Website: https://www.posit.co LinkedIn: https://www.linkedin.com/company/posit-software Twitter: https://twitter.com/posit_pbc To join future data science hangouts, add to your calendar here: pos.it/dsh (All are welcome!

Data Science Hangout | JJ Allaire, Posit PBC | Making data science more open and collaborative

We were recently joined by J.J. Allaire, Founder and CEO of Posit PBC. What made you so interested in open source initially? It was really that the first big software projects I worked on were proprietary software, and I found it disappointing that proprietary software products kind of get very tied up with the company that sponsors them – the fate of that company, the other products that that the company might offer, or who that company gets acquired by really end up affecting the fate of the projects. I also found that while some proprietary software is either cheap or low cost, there’s a certain impediment to adoption associated with the price. As a creative person, I want my work to be available as broadly as possible. I like to make the work available to as many people as possible, but also there’s a dimension of the durability of the work. Is the work going to be around in 30 years or 40 years? What are the things that would make it? So that’s what made open source appealing to me. What are you most excited about at Posit in the next year ahead? It’s going to be related to Quarto, of course, because that’s what I’m spending all my time on. I would say that the thing I’m excited about is that we recognized Quarto is really powerful and flexible, and easy to use for a certain subset of users who are very technical and very motivated, but we actually want to make Quarto available more broadly. So working on tooling that lets both technical and non technical people collaborate over documents, and also lets some less technical people participate in using Quarto. (You can sort of see some of this work in the visual editor that’s in RStudio) Those are the kind of things that I’m focused on for the next year, and I’m excited to see those getting realized. In hindsight, what is one of the best decisions that you ever made for your career or your education? I think this actually has a lot of commonality with talking to a lot of people about their careers. I think when I was about in my late 30s, I had been involved in both developing software and also starting companies. I really learned about myself, that the company part of things – the management and entrepreneurship – I really did not like it all. I didn’t enjoy it. So I kind of said, I’m happy to be involved in starting companies but I’m absolutely not going to do that part, and I’m going to have to find a partner or other people who are excited about doing that part. What I really want to do is focus on engineering and product development. It’s very easy as a company founder to get pulled into all kinds of other things and that’s what happened to me the first 2 times. Just being super clear about that, and saying I won’t even do it unless I can satisfy this condition. I think that’s pretty broadly applicable in that a lot of us accumulate a lot of responsibility in our careers. Some of it is necessary and important for a given role or company, but then eventually being clear about, what do I really like to do and really want to do? What do I feel like I should do or what is put upon me? I know a lot of people now who are in their 40s who have actually managed dozens of people and are like, yeah, I don’t really want to do that. I don’t ever want to have anyone work for me anymore. So I’m going to be really clear about that. I’m going to walk in, and people are going to try to give me people and try to make me a manager, and I’m not going to do it. I think it applies pretty broadly, but just knowing yourself and setting pretty rigid constraints about what you’re willing to do in the workplace and not. Everybody’s different, and both can be really rewarding. I know a lot of people who find management very rewarding, but I know a lot of people who find it really alienating. ► Subscribe to Our Channel Here: https://bit.ly/2TzgcOu Follow Us Here: Website: https://www.posit.co LinkedIn: https://www.linkedin.com/company/posit-software Twitter: https://twitter.com/posit_pbc To join future data science hangouts, add to your calendar here: pos.it/dsh (All are welcome!

Data Science Hangout | Javier Orraca-Deatcu, Centene | Excel to data science to lead ML engineer

We were joined by Javier Orraca-Deatcu, Lead Machine Learning Engineer at Centene. Among many topics covered, Javier shared how his background in finance and consulting led to his interest in data science to automate some of his work - and how he helped get other data scientists together in his organization. (26:31) How did you organize and recruit people for the data science community group at Centene? So I sort of piggybacked from a general data science community chat that we had at the company. There were several hundred people on this of varying backgrounds and expertise levels so there was a lot of conversation happening. There was already a Python group that was meeting– I think every other month. So three weeks after I started, I got really excited about the possibility of potentially creating something similar for R users. It started by just trying to figure out who owns that already existing data science chat and see if they could help support the idea of creating an R user group, something to meet once a month or once every two months. At larger companies especially, getting that type of top-level executive stamp of approval and support can go a long way, especially if that individual is part of the already existing IT or data science function. At the time, I created a Blogdown site. For those of you who are familiar with R Markdown, Blogdown is a package that allows you to create static websites and blogs with R Markdown. Now with Quarto you can do the same thing and create websites. I love the syntax of Quarto. We had partnerships with Posit, so we were able to get some people to come in and do workshops as well. We also had reticulate sessions, where it was a co-branded Python & R workshop where we were looking at ways in which we can actually communicate between teams of different languages a lot easier. I had a great experience with it. Everyone was so collaborative and it was such a great way to see the excitement around what you could do with both R and Python. I think what started as 13 users the first month, jumped to about 100 - 125 monthly users on this monthly meetup. …And on the journey to machine learning engineer, what was the hardest part? (49:10): Because of SQL, I had a really good understanding of at least how tabular data could be joined and the different transformations that could be done to these data objects. I think I would have really struggled without that basic understanding. But having said that, I think the part where I really struggled at first was function writing. Function writing was not intuitive to me. Basic function writing was but in general, I found it to be very complicated and it took a solid three to six months of practice to feel actually comfortable with it. Even when I started building Shiny apps– basic Shiny is quite easy but large functions underpin the entirety of a Shiny app. Everything you do within Shiny is effectively writing functions. The process of learning Shiny and becoming more comfortable with Shiny was very difficult and something that just took a lot of repetitions but it all sort of played together. While people may think of Shiny more as a frontend type of system, it did make me a much better programmer in the way I thought about actual functions and function writing. Other things that I found hard, looking back, I’m sort of embarrassed to say this, was reproducibility of machine learning – being able to reproduce a code set and get the exact same predictions every time. I wasn’t quite sure why this wasn’t working or how to create these fixed views, setting a seed or whatever you need to do to ensure that someone else downstream could replicate your study or analysis and get the exact same findings themselves. ► Subscribe to Our Channel Here: https://bit.ly/2TzgcOu Follow Us Here: Website: https://www.posit.co LinkedIn: https://www.linkedin.com/company/posit-software Twitter: https://twitter.com/posit_pbc To join future data science hangouts, add to your calendar here: pos.it/dsh (All are welcome!

Data Science Hangout | Christina Fillmore, GSK | Open source community collaboration in Pharma

We were recently joined by Christina Fillmore, Data Science Leader at GSK. Christina shared some lessons learned from the pharmaverse and some insight into the community building going on in pharma. For more information on the pharmaverse: https://pharmaverse.org/ “Pharmaverse: Packages for clinical reporting workflows” blog: https://posit.co/blog/pharmaverse-packages-for-clinical-reporting-workflows/ A few tips shared from Christina: I don’t personally believe you need to have a big splash in order to start. I think if you wait for a big, beautiful website and everything to be working before you try and get into anything you’re gonna just be waiting. Find some friends and start developing packages with them. It doesn’t have to be a huge number of people. I wasn’t necessarily around for the whole origin story of the pharmaverse but, part of it grew out of Michael Rimmler and Mike Stackhouse saying we should build some packages together and I built a package for them with Atorus. We built a package or two together, and then started having more conversations with other people. And all of a sudden there was a beautiful website, and things were starting to come together. To some extent, it’s just talking to people and starting to build stuff. Eventually you’ll have enough stuff that you will have your own “verse.” I highly recommend starting. When things aren’t standard, what do you do? And how do you start? Sometimes a nice starting place is a package that helps standardize stuff. Metadata is not really in a standard format in pharma. Everyone has their own way of holding this metadata. One of the first packages that I built as part of the pharmaverse was a package called Metacor. Part of the reason was that we wanted to build automation off metadata, but everyone held it in a different excel format typically, or it was in a database. It’s different for everybody so we needed to have a thing that we could all use. It’s the most boring package in the whole wide world, but that enabled additional audit automation to be run off. From there, we then created a different package called Metatools that does a lot of this automation. But the first step was getting that initial thing we could all agree on. ► Subscribe to Our Channel Here: https://bit.ly/2TzgcOu Follow Us Here: Website: https://www.posit.co LinkedIn: https://www.linkedin.com/company/posit-software Twitter: https://twitter.com/posit_pbc To join future data science hangouts, add to your calendar here: pos.it/dsh (All are welcome!

Data Science Hangout | Eric Nantz, Eli Lilly | Innovation in clinical trials with open source

We were recently joined by Eric Nantz, Director at Eli Lilly and Company. Eric shared his view on the biggest changes in pharma over the past 12 years: A lot of change that happened was an initiative many years ago where we tried to minimize the time from a treatment’s discovery in the lab to when we can actually get that treatment out to patients to benefit from. To do that, we had to do a lot of things differently. There have been reorgs in terms of how trials are designed and more emphasis into other functionalities but within statistics, it actually empowered us quite a bit to push new cutting-edge algorithms for designing, for simulation, and to not just do the traditional analysis for a clinical outcome. The fact that we got this mandate to shorten the time that we’re in the research phase, then we had to really put all hands on deck to put out new solutions. That brought innovation out of necessity but it also opened the door for those in my group at the time to really think differently of how we’re leveraging R in the design space, and become one of the industry leaders in clinical simulation. We definitely have relied on a lot of the functionalities that my colleagues have made. I’m not going to come here and say I know all the ins and outs of every statistical method. That’s why we have a team. Everybody can specialize in their key areas. But we’ve all been able to pitch in and be able to bring that innovation to more novel designs that can shorten that time that a patient has to be in a trial. The industry itself still has a ways to go, but just that emphasis on getting these treatments out to patients sooner organically then brought some new innovations that we were doing in statistics and it really gave us a voice at the table that we could bring some really innovative change to how we were doing things in the past. So certainly that’s been one of the higher-level changes I’ve seen. ► Subscribe to Our Channel Here: https://bit.ly/2TzgcOu Follow Us Here: Website: https://www.posit.co LinkedIn: https://www.linkedin.com/company/posit-software Twitter: https://twitter.com/posit_pbc To join future data science hangouts, add to your calendar here: pos.it/dsh (All are welcome!

Data Science Hangout | Alan Schussman, W. L. Gore & Associates | Data science is not one thing

We were recently joined by Alan Schussman, Data Team Leader at W. L. Gore & Associates, Medical Products. “Data science is not one thing.” This was a recurring theme among comments and conversations in today’s data science hangout with Alan. Data science is about problem-solving I don’t think specific technical skills are the only thing that gets you in the door. We have people who come from analyst backgrounds and tools backgrounds of all different kinds — and can be successful here. There’s an element of being competitive that is rooted in some core technical foundations. However, you can be really technical but not a good problem solver. We need people who can learn technical things but also know what solving problems looks like. If you’re inflexible in how you solve problems, you are not going to be successful. Thinking of interviews I’ve been part of, you see people light up when they explain a problem they solved with different kinds of cooperation and creativity. Seeing this is really fun and helps you stand out. Data science is about compromise There’s a whole lot of what we do in our work that has to do with satisficing — getting to a good enough solution that folks can work with. A lot of technical training is a little too black and white for being able to compromise about, “This is good data that my customers can work with, and I’ll come back and improve it for the next cycle.” You’ve got to be able to compromise. Data science is about communication You’ve got to be able to talk through problems and feel embedded with your customers, so that you’re a partner to them and not just a technical service. Data science is more than machine learning I don’t think we do a service to people the way we set them up for what the data science industry “tends to look like.” I don’t know if it’s the right expectation for people going through data science training to have their eyes on the machine learning engineer kind of career, for example. There aren’t a ton of them. The applications are pretty specific. We’re a pretty sophisticated business, and we’re trying to figure out what some of those things mean to us, and how to effectively use them. Don’t get me wrong, I’m really excited for us to be at that place but without the business need it’s not fair for me to tell people: “Come join my team and be a data scientist the way that the world says data science looks.” It’s going to be technical. It’s going to be interesting. It’s going to be rewarding, but it’s different from that other picture. There isn’t any reason we can’t make people really excited about that kind of work. It’s really complex and the problems to solve are really fun. The platforms we get to work with are cool, but it looks a little different. We’ve got a lot of runway for folks with a broad set of skills. We have to be realistic about what we promise the work is going to look like and when, so that we’re not bringing in people who have a very particular vision of data science. ► Subscribe to Our Channel Here: https://bit.ly/2TzgcOu Follow Us Here: Website: https://www.posit.co LinkedIn: https://www.linkedin.com/company/posit-software Twitter: https://twitter.com/posit_pbc To join future data science hangouts, add to your calendar here: pos.it/dsh (All are welcome!

Data Science Hangout | Marcos Huerta, CarMax | Translating Academia Experience to Data Science

We were joined at the Data Science Hangout by Marcos Huerta, Manager of Data Science at CarMax. A few snippets from the conversation with Marcos at 36:40: What was the most effective asset that you had that led to your transition to your current position? ⬢ A willingness to just try and teach myself new things. In graduate school, I’d done a ton of data analysis, but it was all in an obsolete language that wasn’t going to help me. I had to teach myself Python and R. I think the openness to trying that was key. ⬢ I gave myself a project to figure out how to use Python and understand classes and object-oriented programming, which I did not understand 10 years ago. ⬢ I do think that my work experience – because I had done a lot of non-technical stuff – helped as well. I had this record of professional accomplishment that maybe wasn’t technical but people knew I could think and I had this track record. How do you do the mental folding to translate the many years you spent getting a PhD in astrophysics to a different position? ⬢ The first step for me was not to data science, it was to the science policy world. I think I always had this interest in politics and the government. That first transition came because of these talks at Rice that happened once a month about non-academic careers. Someone who had done science policy and worked at the National Academies of Science and as a Congressional Science Fellow came and gave a talk about what she had done with her physics or astrophysics degree. That really fascinated me. ⬢ From science policy, data science was more practical. There’s a ton of jobs at the entry level for science policy but as you start to work your way up I was running out of things to do. There become fewer and fewer job openings. ⬢ Turns out when I started itching that part of my brain again, I really enjoyed it. I enjoyed the Data Incubator. I enjoyed trying to do the swirl lessons in R, building some Shiny apps, etc. Once I got back into doing technical stuff, I found it was still very satisfying. *non-verbatim transcription, summary of a few insights ► Subscribe to Our Channel Here: https://bit.ly/2TzgcOu Follow Us Here: Website: https://www.posit.co LinkedIn: https://www.linkedin.com/company/posit-software Twitter: https://twitter.com/posit_pbc To join future data science hangouts, add to your calendar here: pos.it/dsh (All are welcome!

Data Science Hangout | Jessie Pluto, Comcast | Taking Initiative with an Idea

We were joined at the Data Science Hangout by Jessie Pluto, Senior Manager of EBI Strategic Analytics at Comcast. Question: As an analyst when you’re working with business partners, you’re just trying to deliver value and insight in a speedy way. So I’m trying to convince analysts to maybe take a bit of a step back and learn and implement something new that can help both them and their business partners in the future. Do you have any advice for how I, as a person trying to get these things up and running, can help to create more of that culture of let’s go ahead and take a step back and do something now that will help me in the long term versus just trying to check boxes as quickly as possible? Answer: It is a constant battle. I feel like it is the place where it requires some strategy because you can’t do it all the time. You have to really recognize when is the right time to pounce on an idea? You have to have the ideas first. Sometimes you have to sit on them for a little while and then you have to just be able to recognize, I think, that opportunity. It’s OK to make mistakes. Sometimes you push something too soon and it might hurt a little bit, but don’t let that kill your motivation. I hate PowerPoint. I hate copy and paste so much. I might have said copy and paste 80 times already. But I hate it. For a long time, some of the reports that I was doing– just to give you an example, Paramount is, like, 30 individual networks - and so sometimes we’re repeating views for 30 networks times five different views at the bare minimum. It’s too many slides, too much copy and paste. I had made a push for, oh, we should convert this to R Markdown or Shiny or something. And same thing– it’s like, well, our stakeholders don’t know how to use that and it’s a server. It’s very private and customer information. And COVID hits, and sports viewing kind of just went away. We had so many questions coming in about, what do we do? What’s going on? What are customers doing? What are they watching? All sports just kind of went completely off the air immediately. And I realized, this is my moment. I created (we were in Hadoop at the time, we’ve since moved but we were in Hadoop at the time) some shell scripts, bash scripts to run at certain days and scheduled it and created this pipeline that I had been messing around with for a while, created an automated R Markdown report. And basically, I was able to give the information that the business was asking for very, very quickly. And they learned how to use it because they really wanted it. And it would have been too much for my very small team to be reporting every single week on what is happening this week. It’d be a huge load on our team to do that every single week from scratch. So basically investing– and I will admit that I spent a little bit of night time on this project - but it was a passion project where I was like, all right, this is my moment to prove that this is a feasible solution, and show that– because we had so many questions coming in. This was one of a huge backlog of questions. I was able to show that, OK, this is done. We’ve automated it. We can use this for other things, for other questions that business owners want every single week and still have time leftover for those ad-hoc questions. Those one-off things that are really important, we’ll have time for that, too, and not miss the report. I think there’s just this strategy that you have to really always be thinking about of when is the right moment to maybe not necessarily ask for approval– to just do something and show the value. Hopefully, you have leaders who will support you in those decisions If it’s the right one and the right moment you can push some of the different tools that were not really supported in the beginning of my career here. ► Subscribe to Our Channel Here: https://bit.ly/2TzgcOu Follow Us Here: Website: https://www.posit.co LinkedIn: https://www.linkedin.com/company/posit-software Twitter: https://twitter.com/posit_pbc To join future data science hangouts, add to your calendar here: pos.it/dsh (All are welcome!

Open Source Chat - {gt} with Rich Iannone

Join Rich Iannone, maintainer of the {gt} package, as he takes questions from the community about the latest in {gt} v0.7.0, and building great looking data display tables with R. Key Resources: ⬡ Get started with {gt} - https://gt.rstudio.com Reach out: 38:48 - How do I ask Rich about {gt}, feature requests, bug reports, how to solve a problem via {gt}? Rich and the {gt} team would love to hear from you. ⬡ Feature requests & bug reports with GitHub Issues, https://github.com/rstudio/gt/issues ⬡ GitHub Discussions, https://github.com/rstudio/gt/discussions ⬡ Ask the community a question, https://community.rstudio.com/tag/gt ⬡ Follow {gt} on Twitter, feel free to reach out and ask questions, https://twitter.com/gt_package Timestamps Rich Iannone Introduction. 03:52 - Why {gt}? - What does {gt} bring to the table? Why so much effort into static, data display tables? 05:50 - Why open source? Why is {gt} open source and why have you dedicated your career to develop open source software? 08:30 - {gt} v0.7.0, Tell us about those new vector formatting functions in {gt}. Why did you include them? Could you show us some examples? {gt}’s vector formatting functions help you customize the styling, look and feel of your values. Converting the output values R gives you, and making them look exactly the way you want them to can be tricky. A lot of work was put into {gt} to give nice value formatting options. You can now access all these outside of a gt table; e.g. in text, in a plot, etc. 22:35 - Could you provide an example or two with the new styling function called opt_stylize()? What kinds of tables can you make with that? Can you extend that with your own tweaks? 28:15 - Can you make your own themes and share them? “How do I create my own custom theme for my table? A theme I can share with the rest of my organization?” 31:58 - What is the distinction between tab_options and the opt_* functions? Why would a function be in opt_* and not tab_options? 34:00 - sub_values() function, to find and replace certain values in your table. 36:50 - What is the current support for latex in {gt} at the moment? “Personally, I much prefer HTML, but for scientific publications, we are asked to provide a LaTeX file.” 42:50 - “In my work, I often produce A4 output in PDF, mainly with ggplot2 content. It would be nice to be able to combine ggplot + gt tables in a similar way {patchwork} works. Having the plot and the table next to it is very useful sometimes.” 44:30 - Interactive Tables with {gt}? 47:45 - “Any plans to make applying of same style to several columns easier? Unless I’m mistaken, the locations argument of tab_style requires one to specify an individual column. See here: https://gt.rstudio.com/reference/tab_style.html#examples." Yes, supply a vector of columns or use tidyselect functions. 49:15 - “Excel output with {gt}? Would be a huge improvement. I often have to produce tabular output that can be easily reused. Usually it means Excel tables. So far I have mainly done this with Python and openpyxl or PyWin32 (through COM). A simple solution in R would be great.” 50:20 - Support for additional output formats with {gt}? Excel, PowerPoint, etc.? 50:25 - {pointplank}, a package to methodically validate your data whether in the form of data frames or as database tables., https://rich-iannone.github.io/pointblank/. Check out the workshop materials at https://github.com/rich-iannone/pointblank-workshop 55:50 - “Are there ways to have grouped rows? I mean when repeated rows have same characters can we merge them to one?” 58:00 - “Is there an ability to add ‘battleship coordinates’ (e.g. column letters & row numbers) to a gt object? This is a standard for table across my org and I’ve been trying to figure out how to implement it.” 59:59 “Do you have suggestions or examples of building out & applying corporate formatting to gt tables (e.g. adding a company logo, company colors, etc.)?” 01:04:30 - “With PDF/LaTeX output for wide tables, it does not shrink the table.”

Data Science Hangout | Matthew Montero, Gen Re | Bringing a Vision to Life

We were joined at the Data Science Hangout by Matthew Montero, Head of Enterprise Data Services at Gen Re. At 4:23, Matthew started us off with sharing the time that focusing on a vision and defining the strategy around that really clicked for him “When I worked in pharmaceuticals, I had the pleasure of having a manager who was very focused on vision. So that’s when I really got a feel for once you have a vision and you can sell that vision, then you have the ability to build as big a team you need. You have to be able to back that up with either ways to improve the business or ways to even improve the organization as a whole. With the knowledge I gained through the experience of dealing with getting consultants, onboarding new hires, and defining the strategy for that vision, I moved on to my current company, Gen Re. It fostered from there, let me take this vision and further define the way I feel it should be at this company and build a full strategy around that. This was about figuring out, from day one when you get the data in ️ all the way to building applications that use that data ️ the self-service route of other people wanting to use that data for their analytical purposes. Let me build that strategy around there. Being able to both build out strategy and communicate that to executives, to different business units, the heads of different business units, moved me up relatively fast in a sense. It’s being very confident in that vision and in the strategy and even the principles around that as well. It’s really laying out the whole vision of how everything is going to be. You don’t go into the technicals yet of how you actually accomplish that, it’s just how you view what it all looks like. And that’s the first thing you got to sell because at least if you have a vision, you have something you can communicate to everyone. And then that’s when you break down now what’s that strategy to accomplish that vision because you can’t do all that in one day. It’s going to take some time. So you have to have individual steps or a strategy to accomplish that. When I was earlier in my career, my boss asked - “You know my vision. How are you going to make that vision happen?” Once I was given that, I sat down and actually really thought through that. That’s the moment it clicked in my head. Like, this is my next step. I want to be able to both define that vision, define the high level strategies to it, and then work with teams to actually make that happen. That was a couple years back and the time it really clicked for me.” ► Subscribe to Our Channel Here: https://bit.ly/2TzgcOu Follow Us Here: Website: https://www.rstudio.com LinkedIn: https://www.linkedin.com/company/rstudio Twitter: https://twitter.com/rstudio To join future data science hangouts, add to your calendar here: rstd.io/datasciencehangout (All are welcome!

Model Monitors and Alerting at Scale with RStudio Connect | Adam Austin, Socure

Deploying a predictive model signals the end of one long journey and the start of another. Monitoring model performance is crucial for ensuring the long-term quality of your work. A monitor should provide insights into model inputs and output scores, and should send alerts when something goes wrong. However, as the number of deployed models increases or your customer base grows, the maintenance of your monitor portfolio becomes daunting. In this talk we’ll explore a solution for orchestrating monitor deployment and maintenance using RStudio Connect. I will show how applications of R Markdown, Shiny, and Plumber can unburden data scientists of time-consuming report upkeep by empowering end-users to deploy, update, and own their monitors. Timestamps: 2:01 - Start of presentation 3:43 - About Socure 6:12 - Model performance matters, deployment isn’t the end of the story 7:26 - What is a monitor? 8:55 - What is an alert? 11:00 - Monitor example 18:09 - Firing an alert from RStudio Connect 19:00 - Why monitor from RStudio Connect? 24:33 - How monitoring drives success at Socure 30:00 - Git-backed deployment in RStudio Connect 36:00 - Shiny app that their account managers see 46:00 - Architecture of a monitoring system 56:00 - Connect hot tip System-wide packages 57:00 - Why did we try Connect for monitoring 59:02 - Why do we keep using it for that:) Resources shared: Blastula package: https://github.com/rstudio/blastula connectapi package: https://github.com/rstudio/connectapi rsconnect package: https://rstudio.github.io/rsconnect/ Intro to APIs blog post: https://www.rstudio.com/blog/creating-apis-for-data-science-with-plumber/ Speaker Bio: Adam Austin is a senior data scientist and RStudio administrator at Socure, a leading provider of identity verification and fraud prevention services.

Data Science Hangout | Mythili Krishnaraj, AXA XL | Platform Governance With a Shared Vision

We were joined by Mythili Krishnaraj, Global Delivery Lead - Pricing and Analytics Platform at AXA XL. Mythili provided a really helpful view into the IT/technology perspective and shared the steps to platform governance at AXA XL. At (24:14) Mythili shares some guidance on how their team manages 200 users: With onboarding of users, they are put into different AD Groups. Some users might only use Workbench and are not publishing content to Connect so they are put in different AD Groups. Something that was initially lacking for us is that we didn’t know who was successfully onboarding or when someone left and we needed to revoke access to reallocate the license. The governance was thought about as what can we do in terms of each steps? First, with the license: 1️⃣ How do you get them onboard? 2️⃣ How do you keep an audit trail of what they are doing? 3️⃣ How can we tell when they are leaving? One other consideration was - what if someone is not able to use the license for 5-6 months? We started putting a timeline around it. If they don’t use the platform for 6 months, we get in touch with them and find out whether they need the license. Otherwise, we take it back. The team has also started their own R training to support new users. We have helped them with a sort of Wiki to put together all of our R resources so that they know who to go to for a request, how to connect to a data source, etc. That sort of knowledge sharing was a requirement. In terms of governance, we have also segregated the environments now: we have separate development and production. In development, we also have staging and non-prod. When they are ready to publish a model, they come through a ticket. We go through it to see what they are deploying, which are the data sources, have they used any hard coded passwords, etc. There is also a validation framework which we are using. Are they using licensed libraries? Are they using proper packages? A few tips also shared at (17:06) for IT and data science teams to successfully work together: Help the IT team understand the value of what you’re doing. Maybe your eventual output takes a week, a month, or even six months. It’s very important for them to be able to understand that value of what you’re going to bring in. Explain to IT the flexibility that you need. Analytics and data science is all about the speed that comes with any platform. It’s always a two-way street. Let them know that you’re here to support the governance, security and stability as well. Say, “I’m going to be really supportive of your guardrails but at the same time I’m expecting XYZ from your team.” Collaboration is required. Each team knows how we work now and there are sometimes tradeoffs for both sides, but we are able to deal with that because we want to do what’s best for the business. This objective is the same both for technologists and the data science world. Where the conflict comes in is when there is no shared vision. To get that shared vision, both teams need to talk. This conversation also reminded me of the meetup with Gordon Shotwell at Socure on Creating Secure Systems for Growth: https://www.youtube.com/watch?v=UnLpB4IDpZU Follow-up blog post on that meetup above as well, “How Data Scientists and Security Teams Can Effectively Work Together” https://www.rstudio.com/blog/how-data-scientists-and-security-teams-can-work-together/ Where to find more? ► Subscribe to Our Channel Here: https://bit.ly/2TzgcOu ► Data Science Hangout site: rstudio.com/data-science-hangout ► Add the weekly Data Science Hangout to your calendar: rstd.io/datasciencehangout Follow Us Here: Website: https://www.rstudio.com LinkedIn:https://www.linkedin.com/company/rstudio Twitter: https://twitter.com/rstudio

Data Science Hangout | JD Long, RenaissanceRe | Empathy When Integrating with Other Tools

We were recently joined by JD Long, VP - Risk Management at RenaissanceRe. JD is a financial risk manager, analytical polyglot, and purveyor of colorful metaphors. As people have recently asked more about building communities, I’ll share this snippet here from 45:29 in his hangout. 🤝 I started the Chicago useR Group 13-14 years ago and the design pattern for that group was, I think, a really good one: 1️⃣ We had about four or five people who were going to get together, drink beer, and talk about R anyway, and what we effectively said was, “let’s get in the types of presentations the four or five of us would like to hear, and then invite other people.” And if they don’t show up, we don’t really care because we were going to drink beer and listen to this anyway because we’re interested in this. And that community grew wildly with me running it like as a benevolent dictator just getting the presentations I wanted to hear. 2️⃣ And then one of the things I observed is we were getting lots of new users of R. So I decided once a quarter we would have a beginner’s meetup– And at the beginner’s night, we would make sure we had two things: Topics appropriate for beginners: like grouping and summing, and getting environments set up or updating packages. All the normal stuff people have friction with. Focus on that. Then we would make sure we had–I would call it now like a learner salon or something. We had a handful of people who were more experienced who said, I will sit at a table and anybody that brings their computer with questions, I will answer. We would have really senior people with lots of experience there doing Q&A, and people could bring their own problems, literally eat pizza, drink beer, and look at code. Those beginner nights were super helpful. So anyway, when people ask about building communities, I recommend those two things.

Focusing on punt returns, this team used tracking data to develop an algorithm to find the optimal path for a successful return, quantify player formations on the field and predict yards remaining on any frame of the return. This year’s winning team will discuss their entry, the R code behind the optimal path and advice for this year’s entrants. Speaker Bio: Robyn, Brendan, Ryker and Elijah are all graduate students in statistics at Simon Fraser University in Vancouver, Canada. They each have a passion for sports analytics and enjoy applying their stats knowledge to the game. Q&A Timestamps: *rough estimate:) 15:00 - Do you think being in a general Statistics graduate program was beneficial to your work? As opposed to more specific like “Data Science” or “Sports Analytics”? 19:00 - Did you calculate PEAT at just a single point in time (at catch), or at multiple points during the return? 30:00 - Is it possible to share the code for future reference? 43:00 - What were the biggest challenges when going through the data? 45:00 - In terms of all your data inputs, do you see this extending to performance data like expected speed, fatigue etc., perhaps from practice etc.? 46:00 - At any point during the project, did you feel like you had hit a cul-de-sac or impasse? 48:20 - How do you get started working with player tracking data? 56:00 - Sounds like you were running the code locally? Were there any specific roadblocks to offloading that to the cloud, or was that just not really necessary?

Data Science Hangout | Tiger Tang, CARFAX | Quantifying the Hours Saved

We were joined by Tiger Tang, Manager, Data Science at CARFAX. Tiger (Chongtai) Tang is dedicated to building the Data Science team specializing in NLP and forecasting. He is a big fan of Shiny and he has a passion for the Data Science community. We recommend checking out Tiger’s 2022 RStudio Conference Talk as well, “Saving 1000 hours with RStudio:” https://www.rstudio.com/conference/2022/talks/saving-1000-hours-rstudio/ How do you sell RStudio in your workplace? ️ Build a work automation process How do you build an automation process? 1️⃣ Look at a typical report & identify all the manual steps 2️⃣ These manual steps can usually be tied into 3 portions: getting the data, wrangling/analysis/visualization, and communication 3️⃣ You can replace these portions with R code, with the help of various R packages What are the three types of automation? 1️⃣ Attended automation - reports that still need human involvement: use R code in RStudio 2️⃣ Unattended automation - don’t need human input, but need to happen at the same time: use RStudio + RStudio Connect 3️⃣ Hybrid - combination of the previous 2, human input will come from the stakeholder & they can kick off processes to get answers: use Shiny + RStudio Connect Ok, time to sell it to decision makers What are the benefits? Reproducibility Less human error Cost benefit (hours saved) Why weren’t they interested when you shared these? The benefits listed above are great for selling to an R user who is concerned about the day to day workflow, but not decision makers who are more concerned about ROI. Update your strategy in highlighting the benefits: Cost benefit (hours saved) - If we go through with this we might be able to save 1,000 hours per year Less human error Reproducibility (as a free add-on travel insurance) It’s still the same benefits, just in a slightly different order. Start with one that does not require too much context to understand. What do you need to do the actual automation? Understand the current process and document it. This includes understanding: ⬢ the business reasons ⬢ the occurrence (daily, weekly, ad-hoc) ⬢ how you will communicate ⬢ how often to update the process so it will not become obsolete ⬢ you are not always the original report owner, so you need to know when to stop and call for additional help. From this you will understand the complexity, impact, and stability & can help you decide which project to start with as well. Top 3 recommendations for automation: 1️⃣ Always start with components: For ex, if you have a process that involves: SQL, Excel, and Outlook - code them individually because the same team will need this again and you can reuse the code. 2️⃣ Test, Test, Test: Capture all the scenarios possible. 3️⃣ Be practical and stay on target: Not everything needs to be fully automated. It’s not about building something cool with R but building something impactful with R. Structure for you: 1️⃣ Identify tasks in your workplace 2️⃣ Build a proposal with the benefits that matter to decision makers in your workplace 3️⃣ Build a requirement doc that identifies the right task to start with 4️⃣ Code by component and do plenty of tasks, while staying on target 5️⃣ Share the progress from time to time Where to find more? ► Subscribe to Our Channel Here: https://bit.ly/2TzgcOu ► Data Science Hangout site: rstudio.com/data-science-hangout ► Add the Data Science Hangout to your calendar: rstd.io/datasciencehangout Follow Us Here: Website: https://www.rstudio.com LinkedIn:https://www.linkedin.com/company/rstudio Twitter: https://twitter.com/rstudio

Posit Meetup | Ryan Derickson, VA | Collecting & Acting on Employee Engagement with Shiny

Led by Ryan Derickson, Veterans Affairs Shiny Executive Dashboards in VA 1:46 - Start of presentation 3:34 - The data used for the application 5:18 - Executives need to know how to help and what to watch out for (AES Exec Dashboard briefs ~2,000 people) 9:08 - Shiny app (Exec dashboard) demo 12:20 - Storytelling within the application 19:22 - Q&A: Is the url available? This is an internal app for VA behind our firewall, so external users aren’t able to access 19:33 - Q&A: My employer would like their data source reference daily, is Shiny the recommended method? A: We have large single efforts (annual survey) rather than continuously updated data, but I’ve seen really effective use cases of that. It depends a lot on how the data is stored and that you can access it through API or database. 20:24 - Q&A: Is there any concern from IT regarding open source tools? A: There is inertia to overcome. You need executive sponsorship to be able to say why the ultimate outcome matters. IT cares about security and maintainability, not the details of the app. A leader who has sway with IT leadership can help them in seeing the value. In VA, there is a really detailed process to go through to get on our federal Azure space, which is slow but you do get there eventually. 21:51 - Q&A: What has been your experience with R and VA? 23:22 - Q&A: Are there limitations on the packages used? 23:44 - Employee engagement & burnout communicated through the app 29:01 - Q&A: How many people are using the app at one time? 30:15 - Q&A: Is the UI done with bslib or javascript and css? 30:49 - Q&A: Where can we learn more about the click and drill-down interface function? 41:20 - Q&A: How long did it take to get the app up and running? 43:22 - Q&A: What was the process for designing the UI? 45:38 - Q&A: What is the return on investment for the VA? 47:00 - Q&A: What would you recommend for learning Shiny? 50:27 - Q&A: For other public sector employees making the case for open source, is there other advice you have? Abstract: Data analysis and visualization is becoming increasingly accessible, yet the difficulty in translating data into action often remains persistent. VA has adopted an integrated approach to collecting & acting on employee engagement data, with a (robust) Shiny app as the centerpiece for the executive-focused portion of that approach. This talk will cover that approach, demonstrate the app, and discuss organizational and service improvements that have followed. Speaker Bio: Ryan Derickson leads VA’s quantitative approach to improving employee engagement, primarily through feedback and related outcome data

Communicating the value of data science | Led by Merav Yuravlivker

Communicating the value of data science Led by Merav Yuravlivker, CEO & Co-Founder of Data Society Four years ago, Merav sent out a small survey to better understand the challenges of data professionals. It quickly spread and hundreds of responses poured in from Frustrated Data Scientists, who didn’t feel understood or have the support they needed. From that, Data Society released the Data Science Communicator Toolkit to help alleviate their pain points. Now, they’ve relaunched the survey to see how they’re doing today - what’s better, what’s worse, and what’s next. Merav will release the preliminary results of the updated survey and talk through how data professionals today can bridge the communication gap to foster better insights and increase their impact. Survey link: https://bit.ly/3pxrejT Data Science Communicator Toolkit: https://www.rstudio.com/champion/business-case (under the section that says build your case with a presentation) Speaker bio: Merav Yuravlivker is the CEO and co-founder of Data Society. She and her team train up thousands of professionals every year across Fortune 500 companies, large organizations, and federal agencies to help them use data better and solve tough challenges. Merav is passionate about delivering the impactful combination of education and data to transform how industries run today. What is a Champion Chat? The champion chat is an informal meetup where we can ask questions to the community and share best practices with each other for advocating for data science at your organization. During these calls, we may also feature a short presentation from a community member who has championed data science and has a few tips to share with us all. *Please note, any presentation portion of this meetup would be recorded, but the open discussion/ Q&A will not. Who? All are welcome - no matter your role/industry/experience No need to register for anything It’s always okay to join for part of a session You can just listen-in if you want You can ask anonymous questions too!

Data Science Hangout | Ivonne Carrillo Domínguez, Bixal | Transitioning to data engineering

We were joined by Ivonne Carrillo Domínguez, Data Engineering Manager at Bixal. Ivonne is passionate about storytelling and empowering data professionals to jump to the cloud. Here’s a snippet (55:00) including a few thoughts that both Ivonne and Brittany shared at the hangout with regards to some people being overlooked for data engineering roles based on their experience: When I am hiring people for a data engineer position - I focus more on the programming skills. If you are a good engineer, you will learn Spark or MapReduce in time. You will end up using certain tools, but in my opinion I wouldn’t say no to someone because of a specific technology. If you find a good candidate, you can teach them or mentor them in specific frameworks. When I started my first job as a data engineer, I didn’t know about big data or Spark. I had a lot of experience with Java and that’s why they hired me. I think knowing how to program is more important - and that’s the philosophy I use. I think what they are looking for when they ask about certain tools is if you have experience with concurrency or parallel jobs. Sometimes you need to think a bit differently with distributed computing frameworks, but if you start playing around and reading about it, it will also help give you an opportunity to land a job. Sometimes when you’re working through a third party like a hiring recruiter, they may not know all of the things that are needed for the role. They’re given the job description and they may not know “I really need someone who has this skill, but if they don’t have this particular one - I’m willing to train on that.” The recruiter might not know that information and this may even change depending on how long the role is open for. What’s best for the candidate in that case is to get as close to the actual hiring manager as possible. Give them your resume and let them know your experience because sometimes they’ll look at your resume and would absolutely love to give you an interview, where the recruiter might say, “oh, you don’t meet X percent of the job description, therefore I’m not going to pass it on.” This is one of the disconnects between having a third party do that interfacing.

Data Science Hangout | Adam Bly, System | Decentralizing decision making

We were joined by Adam Bly, Founder & CEO at System. Adam asks, why haven’t we seen it all connected yet? Primitives for leaders: (12:12) Adam shared how he learned from Daniel Ek, the founder of Spotify - the importance of decentralizing as much of the decision making as possible to increase speed, autonomy, and ownership regardless of the size of a team. This puts a great deal of emphasis on the primitives that you feel are important for every leader in the company and then for their teams to really embrace that, understand and make sure people really get it. This empowers teams to be agile, to be squads, and go off and do their thing. We put a great deal of emphasis at System on a set of first principles that govern how we think about the product and technology, and then tensions that shape any major decision. We put a great deal of emphasis on our values and talk a lot about those and use those as primitives when we’re making product decisions or technology decisions. We also put a great deal of emphasis on the use of data broadly in the company to inform our decision making. By really equipping everybody with those three things that we talk about from day one onward through professional development, 1:1s, and everything at System, it allows for a high degree of ownership, autonomy, and distributed decision making around the company.

Posit Meetup | Afshin Mashadi-Hossein, Bristol Myers Squibb | Framework for Data Collaboration

Led by Afshin Mashadi-Hossein, Sr Principal Scientist at Bristol Myers Squibb Github link: https://github.com/amashadihossein/daapr Other pharma use cases: rstudio.com/champion/life-science RStudio for Clinical Reporting: rstudio.com/solutions/pharma Chat with RStudio: rstd.io/chat-with-rstudio Abstract: For data science teams, data preparation takes substantial investment of time, data science expertise and subject matter proficiency. However, as the name implies, data preparation is typically viewed merely as a means to an end, encouraging creation of expensive but often single-use and fragile elements in data analysis workflows. Rather than seeing data preparation as an obstacle to be removed, we propose a framework that recognizes the time and expertise invested in data preparation and seeks to maximize the value that can be derived from it. Viewing analysis-ready data as a multi-purpose, modularly built product that should lend itself to collaborative development and maintenance, the framework of Data-as-a-Product (DaaP) aims to remove barriers to version tracking and collaborative data development and maintenance. Specifically, the framework, which is entirely implemented in R, enables joint code and data versioning based on git, standardizes metadata capture, tracks R packages used, and encourages best practices such as adherence to functional programming and use of data testing. Collectively, the patterns established by the DaaP framework can help data science teams transition from developing expensive, single-use “wrangled” datasets to building maintainable, version-controlled, and extendable data products that could serve as reliable components of their data analyses workflows. Bio: Afshin is a data scientist who is passionate about putting engineering and computational tools to work to realize the potential of biomedical data in service to human health

Data Science Hangout | Lindsey Dietz, Federal Reserve Bank | Focus on the impact of the output

We were joined by Lindsey Dietz, Stress Testing Production Function Lead at the Federal Reserve Bank of Minneapolis. Lindsey leads a team of quants & data scientists implementing and analyzing stress testing models in the Federal Reserve System. She loves diving into the nitty gritty of data and using R code to better understand the statistical dynamics we observe in the banking sector. Loved kicking off the session with tips for communicating technical results to the business. ⬢ It’s key to think of pretty much every audience as a non-technical audience, even when you have people you know are technical. It’s best not to assume that your audience ever knows the things you know because it’s unlikely that anyone will be as deeply immersed in a problem as you are. ⬢ Focus on the impact of the output first. I like to tell my team that what you might think is the smallest piece of work, someone else is going to think that is magic. I was actually just telling someone this earlier today. They were talking about the coding they had done and I said, “you know, the thing that is going to really impress people is that you generated this automated piece of documentation from your code basically for free.” ⬢ I remember someone at the RStudio Conference talking about “minimizing time to magic” and that is really the impact driver for most people. ⬢ Focus on the impact in your regular words and remove the jargon. ⬢ Trust yourself that you’ve done all the checking, the assumptions, and the technical details. Write that down for yourself and have a good appendix or technical paper to go with your work. ⬢ Non-technical audiences may ask you questions that you didn’t even think about that are really helpful in being proactive for future analysis. ⬢ Practice your translation skills, even if you know they’re not going to understand your world and you’re not necessarily going to understand theirs. For decision makers - bottom lines are important, right? How does this save us time, how does it save us money? These are key concepts that you should keep in mind for non-technical spaces.

Data Science Hangout | Rebecca Hadi, Lyn Health | Transparent & Visible Work

We were joined by Rebecca Hadi, Head of Data Science at Lyn Health. Rebecca is passionate about improving healthcare using data science and machine learning. At 19:11, Rebecca shared her approach to communication with transparent and visible work. Here are 4 things they do on their team to create transparent & visible work: Starting off with an open Data Science channel (different from their team channel) that’s open to the company. For example, if we do an analysis for the sales team - we will post it in that channel and tag the sales team. That way anyone in the company can see the work. We keep conversations in the channel, rather than DMs. A lot of times someone else may be interested in that work. We also have a Google sheet that we call our insight repository. We have that pinned to our channel so when we post analysis, we also put them in our insight repository with one row per analysis. For example: in-patient mortality model, a headline, the link to the PDF, and the GitHub link. The insight repository has been very well received as a place that someone can start when they have a question. I also host a weekly data science prioritization meeting and we use Monday as our project management tool. This has been really helpful because in the past I’ve had some challenges with balancing requests from our clinical team versus sales team and understanding the priority. It can be hard to be that person in the middle. It’s a lot more productive when we can all have that conversation live. The sales team might say, “I need this for XYZ meeting” and you might have to say, “Ok, you know that’s going to push off these additions to the clinical dashboard.” Then the clinical team can weigh in, “We’re okay with that because of XYZ reason” I’m also a really big advocate of a monthly all-employee call and I try to get air time there pretty frequently. Initially it was level setting on “this is what data science is and how my team operates.” That has been successful for setting this idea of, “you are going to ask me something and I’m going to ask you the why behind it.” This helped set the precedent ahead of time where I’m not challenging an idea, but it will help my team produce better work if we understand why you care about this and how you are going to use it because that gives us context in decisions we need to make throughout the process. A few resources shared too: Javier shared: A resource that I just came across last week (def not something I do daily). if you’re wanting to collect / manipulate JSON data with R, Tom Mock has a super-easy-to-follow writeup with several different approaches: https://lnkd.in/gwGxJpcW Luke shared: Data is Plural newsletter is a decent off-the-beaten-path dredger of data sources: https://lnkd.in/grRGqQRA Rebecca shared this book on management, The Hands-Off Manager: https://lnkd.in/gg2TU2mB Where to find more? ► Subscribe to Our Channel Here: https://bit.ly/2TzgcOu ► Data Science Hangout site: rstudio.com/data-science-hangout ► Add the Data Science Hangout to your calendar: rstd.io/datasciencehangout Follow Us Here: Website: https://www.rstudio.com LinkedIn:https://www.linkedin.com/company/rstudio Twitter: https://twitter.com/rstudio

Data Science Hangout | Alec Campanini, Walmart | Using Shiny to make business decisions

We were joined by Alec Campanini, Senior Manager, Merchandising Operations Omnichannel Business Analytics at Walmart. Alec loves to standardize and scale data in a targeted and meaningful way without sacrificing speed of development. (5:12) - Alec shared an awesome example of the way their team is using Shiny at Walmart: Their team’s main scope is “rest of market” - trying to figure out every item that exists in the rest of the market, no matter if it’s in the store, online, through TikTok trends, social listening, whatever it may be. We have a lot of market share data, sales information, pricing over time, and bestseller trends that are popping up. We do a lot to find out where merchants would be lacking inside of a brand. Today I own a Shiny app (which has been alive for about a year and a half now) that is pushed to all merchandising. We have about 12,000 users on it today across all of the merchants and merch-ops. What does it do? Starting off it was insights on 28-30 different retailers in the e-commerce space. With so many items, there are a lot of different contracted data sets coming in. The biggest thing is normalizing all of those to the Walmart hierarchy. We need to have some way to tell a merchant that something from the rest of the market on a different website makes sense for them to look at. Our Shiny app and workflow allows us to quickly identify what percentage we have of a certain brand and drill down into things like: What are the top items being sold? Do I want stable items or trending items? Do I want something that I’ve never seen before? Do I already have the item but need to increase what I’m giving the customer? Do we need to lower the price? Is it shipping too slow? Maybe Amazon has 10 images for the item and we only have 5? An example of this Shiny app helping make business decisions: We released a line of new golf tech products for Father’s Day that came from the Shiny app We had a lot of the sports & fitness merchants find out that we sell a lot more golf technology rather than golf balls online. These are merchants that used to be in the store, but they got into the e-commerce space as a new merchant. They think the trends are going to be the same in-store as online, but they found a different trend inside of our app and were able to launch a whole slew of things this past week, which was really cool. Other timestamps: When making the case for code-first data visualizations over BI tools (25:58) Packages shared in the chat: bs4Dash: https://lnkd.in/gPUBDW72 Rhandsontable: https://lnkd.in/gtYedxzY Bigrquery: https://lnkd.in/gtPM6Pn2" Where to find more? ► Subscribe to Our Channel Here: https://bit.ly/2TzgcOu ► Data Science Hangout site: rstudio.com/data-science-hangout ► Add the Data Science Hangout to your calendar: rstd.io/datasciencehangout Follow Us Here: Website: https://www.rstudio.com LinkedIn:https://www.linkedin.com/company/rstudio Twitter: https://twitter.com/rstudio

Data Science Hangout | David Meza, NASA | People analytics for getting to the moon

We were joined by David Meza, AIML R&D Lead, People Analytics at NASA. We had a great chat about people analytics for getting to the moon and beyond Here are a few snippets: What areas do you focus on in people analytics? (5:19) A lot of our focus is around natural language processing, graph algorithms, and graph databases. We create a knowledge graph & apply various algorithms to be able to deliver answers. An example of this is around our skills and competency capabilities. Trying to get back to the moon and onto Mars, we need to identify the various skills and competencies that we have in our individuals. From a human perspective, that’s very labor intensive. We’re trying to use some of the concepts I’ve mentioned to be able to extract NASA-specific competencies from individuals or people applying for jobs to see how they align to our workforce. We’re starting to develop pipelines and methods to say: • We’ve got gaps here • Or here’s your career path • Here’s your training path • Here are the number of individuals we have that meet 70% of our skills and we need to upscale them to the next 30% People analytics can be broken into so many different areas: • Attrition • Time to hire • Recruitment capabilities • Learning/ development With regards to skills for people analytics: • NLP is a good tool to have because a lot of the data we have is unstructured. We need to be able to pull from that. • Understanding various classification models, how you’re grouping individuals & understanding various metrics within the HR area. How much of people analytics is data science and predictive modelings versus reports and business intelligence? Right now everybody does a little bit of everything When I first got here, they were primarily focused on reporting and creating some type of visualization Over the last couple of years, we’ve been trying to break into a group that focus on reports in general and a group looking more at the data analytics & modeling, creating the various algorithms that we can utilize for extracting skills and competencies or looking at our attrition models, for example. Ideally, I would break it down to 5-6 visualizers, 10 data scientists and 4-5 data engineers or architects.

Data Science Hangout | Tanya Cashorali, TCB Analytics | Saving millions with a Shiny app

We were joined by Tanya Cashorali, CEO & Founder at TCB Analytics. Tanya is passionate about playing with data but using it for good causes whenever possible. Energized by working with ambitious people on difficult problems. I’m a huge advocate of rapid prototyping data products using Shiny and can talk about it for hours! What was your biggest win for a client? (23:30) We’ve had a lot of wins moving someone from Excel into a reproducible R pipeline and then displaying all the results in Shiny. One example is a pharmaceutical company that was analyzing clinical trial data super manually, generating reports in Excel and putting together a PowerPoint weekly. It probably took about 20 hours of multiple people’s time. We made a Shiny app and that turned this into pretty much no time at all. They sent us the data and it was updated monthly. They were able to then take that Shiny app to senior management and clinical trial managers to make decisions based on data very quickly, helping them understand which clinical trial sites were having problems. Another similar one at another pharmaceutical company was focused on drug manufacturing, where there are a lot of things that can go wrong. When there’s a contaminant in a batch, it can basically cause millions and millions of dollars in company loss because they have to shut down manufacturing completely until they identify the problem. This involves going up and downstream of these different drug products to identify the issues. It was taking a team of 5-10 people sometimes 6 months to identify the problem. Meaning for 6 months, you’re not able to manufacture drugs. We built a Shiny app that built out a D3 directed graph. This enabled one person to go and type in the drug compound and see everything up and downstream. It took that one person now maybe a week or several days to identify the problem now. That’s an instance where you could say this is literally millions of savings from a Shiny app. To me that just shows the power of R and the ability to really streamline manual processes.

Enabling Citizen Data Scientists at Dow Chemical with Posit Academy

Led by James Wade, Associate Research Scientist at Dow Chemical Timestamps: 2:46 - Start of presentation 5:25 - Goal: “apply science and engineering technical expertise along with data science tooling to innovate in the materials science arena.” 6:36 - What does citizen data science mean? 8:05 - Data science as an interdisciplinary endeavor - looking to build a community of innovators 9:30 - Translating data to decisions 11:03 - Guidelines for success (data organizations, data access, data analysis, value preservation) 13:30 - Welcoming new users in an approachable, collaborative, and secure workspace with RStudio Team 14:25 - Making sure you can rapidly deploy your insights to others 16:25 - What is RStudio Academy? 20:55 - What do you need for academy? (Academy learners: 5-7 per cohort, cohort mentors from RStudio & your group, and a project - the closer to your work the better) 22:15 - Who is a good candidate? 23:55 - Who might not be the best candidate? 26:00 - What makes a good cohort? (similar work group, time zone, and skill level) 27:27 - Feedback (Are they still using the content they learned? 16 out of the 17 survey respondents were still writing code 6 months after) 31:42 - Community building (want to have a landing zone for people to continue to learn) 32:31 - RStudio Academy success story at Dow 35:30 - Start of Q&A portion Questions: 36:00 - How do you help someone who knows coding would be useful but can’t motivate to take 5 steps back to take 10 steps forward? 37:55 - How can more advanced users participate in developing curriculums? 39:44 - Does Academy also teach good coding style and version control? 41:00 - If you’re trying to “sell” Academy to the individual who would fill the group mentor role, what level of commitment and bandwidth do they need to have? 42:13 - Is the type of data you work with relevant to the work you do at Dow? or random / set datasets regardless of which company you’re with? 43:00 - What other ways of teaching R have you tried (or considered) at Dow? How does Academy compare? 44:55 - What is the duration of RStudio Academy? 46:15 - Can you have multiple cohorts go through at the same time? What if we want to up-skill hundreds of people? 48:20 - How did you find out who might be interested and get the word out? 50:08 - Advertising that you help learners up-skill in coding seems like a good way to set your company apart from others, are you hiring? 51:25 - After the RStudio Academy 10 week training is the Academy team still available for questions, support or consult? 53:01 - Is Academy only for R? 53:38 - How can a data science student participate in RStudio Academy? ( https://www.rstudio.com/conference/2022/workshops/intro-to-tidyverse/ ) 54:44 - How do you collaborate with others outside of Dow? 57:20 - How does RStudio Academy handle sensitive data? 1:00:20 - Do you have statistics on how many graduates are still using R? Abstract: In chemistry and materials science research, data is messy, unstructured, and scattered. Solving this problem requires researchers to deeply embed within data generation and analysis workflows. We are on a multi-year journey to equip scientists and engineers with guidance and tools to extract insights from their data. To this end, we have developed a set of 15 guidelines designed to move our organization toward a collaborative, reproducible work process in a dynamic data-diverse environment. In this talk, I will share our lessons from this journey learned through teaching, community building, and collaboration with a particular focus on the integration of language agnostic RStudio tools, products, and programs. I will especially be focusing on our experience with RStudio Academy. Speaker Bio: James is a research scientist working in the chemicals manufacturing industry as part of a research and development team. James applies materials characterization and data science with a special interest in sustainable materials design to develop new capabilities for research. His current focus is on augmenting materials characterization innovations with statistical analysis, machine learning, and data visualization.

Rich Iannone || New features in {gt} 0.6.0! || RStudio

00:00 Introduction 00:18 sub_missing() 03:51 Markdown formatting in sub_missing() 04:51 sub_zero() 07:34 sub_small_vals() 13:08 sub_large_vals() 16:25 final thoughts A new version of the R package {gt} has been released! We are now at version 0.6.0 and there are now even more features that’ll make your display/summary tables look and work much, much better. Let’s run through some of the bigger changes and see the benefits they can bring! New functions for substituting cell data We now have four new functions that allow you to make precise substitutions of cell values with perhaps something more meaningful. They all begin with sub_ and that’s short for substitution! sub_missing() (formerly known as fmt_missing()) Here’s something that’s both old and new. The sub_missing() function (for replacing NAs with… something) is new, but it’s essentially replacing a function that is old (fmt_missing()). The missing_text replacement of “—” is actually an em dash (the longest of the dash family). This can be downgraded to an en dash with “–” or we can go further with “-”, giving us a hyphen replacement. Or, you can use another piece of text. If you’re using and loving fmt_missing(), it’s okay! You’ll probably receive a warning about it when you upgrade to {gt} 0.6.0 though. Best to just substitute fmt_missing() with sub_missing() anyway! sub_zero() The sub_zero() function allows for substituting zero values in the table body. sub_small_vals() Next up is the sub_small_vals() function. Ever have really, really small values and really just want to say they are small? With sub_small_vals() we can reformat smaller numbers using the default threshold of 0.01. Small and negative values can also be handled but they are handled specially by the sign parameter. Setting that to “-” will format only the small, negative values. You don’t have to settle with the default threshold value or the default replacement pattern (in small_pattern). This can be changed and the “x” in small_pattern (which uses the threshold value) can even be omitted. sub_large_vals() Okay, there’s one more substitution function to cover, and this one’s for all the large values in your table: sub_large_vals(). With this you can substitute what you might consider as too large values in the table body. Large negative values can also be handled but they are handled specially by the sign parameter. Setting that to “-” will format only the large values that are negative. You don’t have to settle with the default threshold value or the default replacement pattern (in large_pattern). This can be changed and the “x” in large_pattern (which uses the threshold value) can even be omitted. Final thoughts We are always trying to improve the gt package with a mix of big features (some examples: improving rendering, adding new families of functions) and numerous tiny features (like improving existing functions, clarifying documentation, etc.). It’s hoped that the things delivered in gt 0.6.0 lead to improvements in how you create and present summary tables in R. If there are features you really want, always feel free to: File an issue: https://github.com/rstudio/gt/issues ) Talk about your ideas on the Discussions page: https://github.com/rstudio/gt/discussions Learn more about the gt package here: https://gt.rstudio.com/ Got questions?

Tom Schenk & Bejan Sadeghian | Making Microservices Part of Your Data Team

Making microservices a part of your data science team Led by Tom Schenk & Bejan Sadeghian at KPMG Timestamps: 1:09 - Start of presentation 4:00 - Challenges and trade-offs of a growing team (how I stopped worrying about hiring) 8:14 - What are microservices? (help separate out the different layers of an app) 9:36 - Hosting other web technologies on RStudio Connect (ex. React) 12:25 - Simple Hello World example of microservices 16:00 - Reason to separate out logging 17:15 - How to design & plan microservices (moving from a monolithic Shiny app) 17:51 - Challenges to getting started with microservices 21:02 - How do you address getting started? (domain driven design) 23:17 - Applying cloud design patterns 25:37 - Separation of development duties 27:22 - Addressing any risks that come with microservices 29:17 - Considering costs and benefits 30:11 - Microservices in action: demo of KODA app (making changes to the organization) 36:21 - PowerBI interacting with the same microservice from Connect 38:30 - Growing teams face a trade-off of complexity and simplicity (KPMG’s path) Questions: 43:28 - Can you use a Shiny front end together with a microservice backend? 44:09 - Do you hire separately for back-end data science development and front-end Shiny UI development? 46:00 - Are all microservices managed by a centralized unit? 47:02 - Who can access RStudio Connect in your organization? 48:29 - When you decided to go the microservice route, what was your first step? 50:47 - What roles are you hiring for? 52:20 - Might you suggest some web service servers that host R-based or Python services? 53:33 - Are apps build with microservices as responsive as those that adopt a monolithic architecture or do microservices introduce a lag? 55:09 - Can you show the back-end response data through developer tools? 56:45 - Can you speak more about the logging microservice? Did you build it ground-up or did you adopt an off-the-shelf package or app? Abstract: Whether or not you’ve heard of microservices architecture, you may want to know how microservices can help you scale R-based applications across an enterprise. As data science teams—and their applications—grow larger, teams can experience growing pains that make applications complex, difficult to customize, or challenging to collaborate across large teams. This meetup will discuss what microservices are, how it compares to Shiny, how it can help a data science team, and how you can deploy microservices using your RStudio Connect environment. This meetup will help you understand several key items: • The basic concept of microservices and benefits, such as making your code modular, domain-driven design, and reducing the complexity of application development, and facilitate larger development teams. • How to use the Plumber package to deploy APIs as part of a microservices architecture. • How you can work with front-end development teams using their preferred framework (e.g., React, Angular, Vue) using RStudio Connect. We will show a widely-used application built using a microservices architecture and hosted in RStudio, including before-and-after comparisons to show the strengths of a microservices framework leads to a better-looking and better-functioning application. Our team will discuss the journey and growth to arrive at the new approach to make development easier within a quickly growing group. Speaker Bios: Tom Schenk Jr. is a researcher and author on applying technology, data, and analytics to make better decisions. He’s currently a managing director at KPMG. He has previously served as Chief Data Officer for City of Chicago. Bejan Sadeghian is a director of analytics at KPMG and leads data science development, which spans from advanced analytics to machine learning engineering.

Data Science Hangout | Travis Gerke, PCCTC | Tips for Very Remote Work

We were joined by Travis Gerke, Director of Data Science at The Prostate Cancer Clinical Trials Consortium. Travis is an enthusiastic proponent of the use of R for data science in the clinical trials space and an advocate for productive remote work environments. Tips for very remote work Ok, first things first - how do you ensure you have internet? I use a 5g Netgear hotspot and have redundant phone plans with T-Mobile, AT&T, and Verizon. It depends where we are and what kind of service is going to be best, but I’ve never had a challenge streaming videos or with Zoom. If you do get a hotspot, $20 boosters can be tremendously helpful too and help funnel the signal into your hotspot a bit better. If you want to geek out on this, the best resource is rvmobileinternet.com. Even in the remotest places we’ve been, I was still able to maintain Zoom meetings. On a week where I am furthest from civilization, I will plan ahead and focus more on learning and heads down work. It’s actually kind of good it gives you a little bit of space from the usual grind of meetings.. How do you balance the time you can be available for conversations or when you’re traveling It’s something that one has to be very intentional about and communicate broadly. I do work odd hours, because I’m West Coast now and most of my colleagues are East Coast. I try to wake up early and stick to their schedule. It really comes down to communication. I will let people know if I’m traveling and block time on my calendar. I think async is the future of most work environments for data science. I’d recommend checking out content from Chris Herd on Twitter too: https://twitter.com/chris_herd If I send an email at a time like 2am, I make sure to communicate that if I’m sending an email, it doesn’t mean I expect anyone to see or respond at that time. A few people mentioned putting something in an email signature to let people know. Here’s an example: “I work on a flexible work schedule and across a number of time zones so I’m sending this message now because it works for me. Feel free to read, act on or respond at a time that works for you.” What tools are there for async work to work through something complicated without meetings? A few ideas and tips shared from the group: We lean into github whenever we can. The process of writing down where you’re stuck and/or how you solved something is good. When working with non-data scientists, sometimes you just have to have the meeting and that’s fine. It can be a lot more efficient that way but the drawback is that you don’t end up documenting. Writing things down reduces those institutional knowledge silos. People mentioned using: Slack, video messages on Slack, Teams, Loom for sharing video screen shares, snagit, Discord, Fuze, Zoom whiteboard Where to find more? ► Subscribe to Our Channel Here: https://bit.ly/2TzgcOu ► Data Science Hangout site: rstudio.com/data-science-hangout ► Add the Data Science Hangout to your calendar: rstd.io/datasciencehangout Follow Us Here: Website: https://www.rstudio.com LinkedIn:https://www.linkedin.com/company/rstudio Twitter: https://twitter.com/rstudio

Data Science Hangout | Alice Walsh, Pathos | Improving an Interview Experience

We were joined by Alice Walsh, PhD, VP of Translational Research at Pathos. Alice works in drug development, where she is excited about the potential of computational research to yield breakthroughs for patients. Loved that Alice also asked this question back to the audience: How do I make an interview a good experience for a candidate? Or have you had any nightmares that’d be helpful to share? A bunch of thoughts shared from the group: ⬢ I’ve had way more success not giving a technical interview, and having the technical interview be more of a discussion where I’m not even asking them to whiteboard anything or it’s just talking. ⬢ If I asked them, “how do you develop a shiny app”, I’d much rather someone tell me I’ve never developed a shiny app in my life but I use R Markdown every day. That tells me a lot about their ability to actually jump in and learn something new and their transparency. ⬢ I’m much more interested in the process. How do people approach a problem and solve challenges that they encounter versus the specific project they worked on because they’re not going to work on that project ever again with me. It’s going to be a new project so they will need to learn something anyway. ⬢ I’ve had success hiring from meetups or hackathons. Seeing people here and the way they problem solve gives you a lot of insight about these individuals. ⬢ My company actually does do a technical interview and we give candidates a data set while they’re on site or in a Teams meeting. We give them an hour to see what sorts of insights they find with a few very specifically directed questions. What we’re often looking for is not someone to have perfect answers to those questions - it’s really about understanding how they looked at the data set, what other information they want, and what do you wish you had more time to do. You get to see how people work through something and it’s okay if they don’t have a perfectly polished presentation. ⬢ I’ve had a nightmare interview that became a pop quiz on R stuff. What are all the packages in the tidyverse (and at the time I didn’t use tidyverse I was base R) ⬢ A nightmare one that sticks in my head was, please describe in detail the differences between Python 3 and Python 2. ⬢ I think, “this is something I would Google” is a valid answer sometimes because even if I don’t know this, I know where to find it and am really confident in my ability to Google this. ⬢ Honestly if I ask somebody a question and they said this is something that I know I could find the answer to, that would be a perfect answer to me. Not knowing but knowing where to find the information great. ⬢ I went on 3 interviews and they each had a technical part where for every single one of them the answer was: dynamic programming. They must have gone somewhere and decided that was the algorithm to ask about. I found that a bit ridiculous because it wasn’t relevant to what they were working on and it was off-putting. Now, when I interview people I try to make it more of a conversation around the data and what we might actually be doing. ⬢ I have an optional take home: “here’s a data set, take an hour and tell me something. Use whatever tools you want: Excel, R, Python, an abacus.” The key thing I want to see is a written output of what you did. I’m still on the fence, though, because I know a lot of people are anti-technical component. I’m still trying to figure out if it is really helping us make the best hiring decisions. Also wanted to share a link to a job posting on Alice’s team! She has simplified to just one posting, but they have a couple of openings. They are hiring both for more experienced scientists and folks transitioning from academic research and no drug development experience: https://www.indeed.com/viewjob?t=senior+computational+biologist+data+scientist&jk=204065f326f6e803&_ga=2.142078395.801277873.1653586940-640826182.1637348361 Where to find more? ► Subscribe to Our Channel Here: https://bit.ly/2TzgcOu ► Data Science Hangout site: rstudio.com/data-science-hangout ► Add the Data Science Hangout to your calendar: rstd.io/datasciencehangout Follow Us Here: Website: https://www.rstudio.com LinkedIn:https://www.linkedin.com/company/rstudio Twitter: https://twitter.com/rstudio

Data Science Hangout | Lindsey Clark, Healthcare Bluebook | Measuring success of data science

We were joined by Lindsey Clark, Director of Data Science at Healthcare Bluebook. Evolving and Leading a Data Science/AI First Organization. One of the topics of discussion (33:46) was measuring the success of a data science team and calculating ROI. How do you measure success for a data science team? Lindsey shared a few tips from her experience at two different organizations: One measure of success was the conversion rate of projects. How many projects come to us and what percent are actually converted to an actual deployment? Our target was 5% which may sound low, but the idea was that we want to fail fast. It can be like the drug discovery mentality - if things aren’t going to work, we want to know early on. We also have targets around the number of specific models we wanted - what we called our data science portfolio library. They didn’t need to be really fancy machine learning, but a lot of them were business logic sort of ranking models. Another measure was product value and financial targets around that. Could we pinpoint that our model went into the data product and it resulted in more clients contracting with us or greater revenue because we were able to upsell a data product due to another feature we added. In my position now, we have recently been acquired so we are working on the success measures and what that looks like. We do utilize the Outcomes and Key Results (OKR) Strategy from the Measure What Matters book. We plan OKRs quarterly and try to plan projects that are really no longer than three month increments in order to keep things going and satisfy the business. Data Science ROI can of course be a difficult thing to measure. Data science can be a capital expense at times and sometimes you have to look at this team that’s going to do high risk projects as research. Things are going to fail and that’s okay. We’re willing to invest the money for our team and absorb that cost for what we potentially get out of the team in terms of deployed solutions, specific insights, and research that are valuable to the business.

While both languages have unique strengths, teams frequently struggle to use them together: ⬢ Data Scientists constantly need to switch contexts among multiple environments. ⬢ Data Science Leaders wrestle with how to share results consistently and deliver value to the larger organization, while providing tools for collaboration between R and Python users on their team. ⬢ DevOps engineers and IT Admins spend time and resources attempting to maintain, manage and scale separate environments for R and Python in a cost-effective way. Join David Aja in this meetup, which will highlight how other data science teams are able to solve these problems with RStudio Team by: ⬢ Combining R and Python in a single data science project. ⬢ Launching and managing RStudio, Jupyter Notebooks, JupyterLab, and VS Code from the RStudio Workbench environment ⬢ Sharing Jupyter Notebooks, Python APIs via Flask, Dash, Streamlit, Bokeh, FastAPI, Shiny, R Markdown, etc. with the business through RStudio Connect. ⬢ Controlling and distributing Python and R packages with RStudio Package Manager.

Data Science Hangout | Wayne Jones, Shell | Thinking Empathetically & Using Your Initiative

We were joined by Wayne Jones, Principal Data Scientist at Shell. Wayne has been using R since its first inception and is passionate about open source solutions. During the hangout with Wayne, he brought up the point of thinking empathetically when communicating. Here are a few other tips shared among the group: 1️⃣ If you spot someone who you think is really good at communicating and you’re impressed by them - buddy up. Tell them you like the way they did that, can you give me a few tips and hints? 2️⃣ With data science, you can focus on a very small area sometimes and get obsessed by the details. Step back, step back, and step back some more so that when you’re presenting a problem you give the bigger picture and narrow into the data science details. 3️⃣ If you think more empathetically, this will also go a long way. Instead of thinking about it from a data science standpoint, put yourself in the customers or client’s shoes. With more empathy, you make yourself a better consultant. 4️⃣ Try using your team meetings (scrum meetings for example) to practice presenting in front of people, even something for 5 minutes where you need to learn to be succinct about it. 5️⃣ Think about when you were a child and bringing something in for show and tell. When they get to bring something they really care about, they are thinking more about the toy that they brought in rather than presenting. 6️⃣ There are lots of R meetup groups that are always looking for volunteers to speak at events! Lots of opportunities to practice there! 7️⃣ Learn about everyone else’s role so that you can talk their language - “BE RELEVANT” to your teams Where to find more? ► Subscribe to Our Channel Here: https://bit.ly/2TzgcOu ► Data Science Hangout site: rstudio.com/data-science-hangout ► Add the Data Science Hangout to your calendar: rstd.io/datasciencehangout Follow Us Here: Website: https://www.rstudio.com LinkedIn:https://www.linkedin.com/company/rstudio Twitter: https://twitter.com/rstudio

Posit Pharma Meetup: R for Clinical Study Reports & Submission | Yilong Zhang

Presenter: Yilong Zhang, PhD During the meetup you can ask questions here: rstd.io/pharma-meetup-questions (anonymously or with your name) Abstract: The use of open-source R is evolving in drug discovery, research, and development for study design, data analysis, visualization, and report generation in the pharmaceutical industry. It is critical to enable the ability to produce tables, listings, and figures (TLFs) and submit results to the regulatory agency using R. We developed R packages (r2rtf, pkglite) and reference book ( https://r4csr.org/ ) to simplify the workflow for an organization to complete those tasks. Based on the proposed workflow, the first pilot project has been successfully submitted to FDA by the R consortium R submission working group ( https://rconsortium.github.io/submissions-wg/). Bio: Yilong Zhang is a biostatistician at Meta (and was previously at Merck). He has worked with a group of statisticians and programmers to demonstrate the capability of using R for regulatory work. Other research interest include statistical methods in study design, missing data, and survival analysis with more than 25 papers published in peer-reviewed journals. Before joining Merck, he earned Ph.D. degree in Biostatistics at New York University.

Data Science Hangout | Michael Chow, Posit | Exploring Team Structure w/ Data Scientists & Engineers

We were joined by Michael Chow, Data Scientist and Software Engineer at RStudio. Michael also previously led a team at the California Integrated Travel Project. On this week’s hangout there were a lot of thoughts shared on structuring a data science team from both Michael and the broader group: ⬢ Jacqueline Nolis also shared thoughts on this on a data science hangout that there were virtues to different ones, but ended up sold on the decentralized model where data scientists are embedded in teams: https://youtu.be/CcPE29bYGVo?t=325 ⬢ Michael agreed that data scientists and analysts should be sitting with the teams that they’re pushing out reports for. Otherwise, I would be trying to send people into those teams to figure out their priorities. ⬢ A data scientist should work with a Project Manager or whoever’s leading the team to push up metrics but also help change the roadmap. ⬢ It leaves a tricky question of where data engineers should be and how they should interact with the team. Today data engineers are often doing more tooling empowerment, so it can be okay to have them a bit more centralized and connect to the data scientists to enforce best practices or enable new pieces for them. ⬢ I think a nice model is for data scientists/analysts to live in the teams and data engineers to be like spokes of a wheel where then the data scientists connect with them and work closely to enforce better best practice and enable new important things. ⬢ Tatsu shared that in thinking of the structure, it’s also important to find your translators and to use the power of feedback. Reach out to those people to start to put that feedback into action. ⬢ George shared that insurance companies have come from a really traditional landscape where they have lots of actuaries working on lots of excel spreadsheets and there can be a lack of knowledge sharing and tool sharing. This is where the data science element comes in. To me, within the organization, you need to have this team which is a mini-spoke if you will, because they are central to the actuarial team. If they are too far removed and they’re back with the IT team, you end up with the old problems because they may not get the business concept communicated back. It’s all about getting enough skills, so they can get stuff done, especially proof of concepts. Maybe after that you can take a step back and then start to look at the centralized model again. ⬢ A central team can help converge to what they see as best practice, but if you’re pushing out something new, exploring a new line of work or area it can be important to set the data engineer there to actually do whatever they need to. Make sure that the converging doesn’t stifle creativity or prevent a team from doing the right thing. ⬢ Manny jumped in to share the perspective from data science being with IT as well, data science is a new field for their company (in real estate) and there’s an identity of where does data science fall. The IT team is fantastic and they’re very structured. Data science is so fluid and creative and non structured at the moment, so you kind of have to look at where it actually should fall. please note that some of the points above are summarized and not 100% actual quotes. Resources shared: ⬢ Tatsu shared in the chat, a few projects that Michael is working on: vetiver: https://vetiver.tidymodels.org/articles/vetiver.html, siuba: https://github.com/machow/siuba ⬢ Libby shared a helpful tip on creating a 2 minutes YouTube video with a cover letter, to get the attention of a hiring manager ⬢ Javier shared an example Shiny app used in an interview: https://javierorraca.shinyapps.io/Bloomreach_Shiny_App/ ⬢ Michael mentioned David Robinson’s screencasts: https://www.youtube.com/channel/UCeiiqmVK07qhY-wvg3IZiZQ ⬢ Michael mentioned an article on “What data scientists really do according to 35 data scientists”: https://hbr.org/2018/08/what-data-scientists-really-do-according-to-35-data-scientists ⬢ Rachael shared a blog post link where Jacqueline Nolis talked about team structure as well: https://www.rstudio.com/blog/building-effective-data-science-team-answering-your-questions/#Structure ► Subscribe to Our Channel Here: https://bit.ly/2TzgcOu ► Add the Data Science Hangout to your calendar: rstd.io/datasciencehangout ► View the Data Science Hangout site here: rstudio.com/data-science-hangout Follow Us Here: Website: https://www.rstudio.com LinkedIn:https://www.linkedin.com/company/rstudio-pbc Twitter: https://twitter.com/rstudio

(A data scientist who onboards new tools, deploys solutions, support existing standards. They work closely with IT to maintain and scale analytic environments. They influence others in the organization to be more effective, and are passionate about making data science a legitimate analytic standard) 24:04 - Building a business case (introducing rstudio.com/champion) Join us for future champion chats the 4th Monday of every month (not the date I said in the recording) rstd.io/champion-chats Let’s admit it. Getting to use the tools you want sometimes needs a little convincing. We’ve had the opportunity to meet so many wonderful people from the community. People that: organize meetups in their own communities, spend time after-hours teaching their co-workers, solve business problems at work with Shiny, write blog posts to help others, and so much more.. People are doing amazing things with data science, yet so many are still in a position where they are not able to make the case for it at their own organizations. Hear from Kelly O’Briant on how you can start to navigate the internal process and advocate for great analytic infrastructure as a data scientist. Whether you’re getting pushback about using open-source, being told to use a BI tool instead, or just unable to find the other data scientists at your company - we want to help make this process less frustrating. Come hang out and chat with us! *Please note, only the presentation portion of this meetup was recorded, the open discussion and Q&A was not.

Data Science Hangout | Tegan Bunsu Ashby, Brooklyn Nets | Showing the Difference You’re Making

We were joined by Tegan Bunsu Ashby, Senior Software Developer, Brooklyn Nets. Tegan works at the intersection of data and design, building applications and visualizations to empower front office decision making and help win basketball games. Towards the end of the hangout, there was a great question from Trevor: How do you show that you are making a difference? One of the joys and terrors of being in a data intensive role for a team is that you can’t point to oh, we did X or we recommended Y and now we have an NBA championship. It has to be - does analytics and investment in data at a league level indicate that you’re going to have sustained success? The investment in analytics departments and the success of teams that have been able to do so is indicative of how teams are evaluating the value of that data. It’s really nice to say, but we also need to hold ourselves accountable. When you’re using all this time and resources - you have to sit back and think, does this contribute to winning? Does it help us make better decisions? At certain pressure points, did we create an environment where it was easier to negotiate a trade or pull the trigger on drafting a certain player over another? Were we able to support that in a way that was actionable, returnable and implemented? You have to communicate that.

Data Science Hangout | Daren Eiri, Arrowhead General Insurance | Building a DS Playbook

We were joined by Daren Eiri, Director of Data Science at Arrowhead General Insurance. Daren is passionate about building creative solutions within the insurance industry using data, statistical modeling, and cloud technology. What do you do to ensure your ideas or solutions are well received by internal customers? Daren shared that they have a data science playbook for building out models. This generally follows the path of: initial kickoff, understanding what their business problem is, and if we do build out a solution - what is it going to look like? Frequently meet with the business stakeholders. Whenever you’re making major decisions or have questions about something, make sure that you reach out to them about that. Make sure that it’s part of their business workflow. If they’re adding this new feature, how is the business going to use it and continue using it so it doesn’t get left in the dark. In terms of making sure that they’re onboard, we talk about their data and what it looks like. This is a service to the team because they may not have looked at the data at that grand of a scale. They may be more used to looking at it quarter by quarter or year over year. We look at the data and provide the perspective that we’re seeing. We always ask for their hypothesis and what they think will lead to what we’re trying to predict. This helps us understand what their problem is and include their own ideas into the project as well. That results in some ownership on their side too because they are partnered with us. When we have the model built out, we evaluate it and see the accuracy. We provide them with several examples and the variation of that data to show the limitations of what that final product will look like. When you’re spending the time walking through the process and they see it working, this helps getting them onboard.

Data Science Hangout | Jennifer Listman, Statespace | Culture that Helps Avoid Burnout

We were joined by Jennifer Listman, Director of Research at Statespace. Jenny likes mining multidimensional datasets to find valuable unknown unknowns. One of the questions that had a lot of people sharing in the chat as well was: ““How do you ensure a work-life balance to avoid burnout?”” ️ A few thoughts: The culture of the team matters. Make it okay to take personal time in the middle of the week to go to doctors, take children somewhere, etc. If it’s a family member’s birthday, let people do what they need to help them celebrate that person. Having that freedom is important. As a manager, take time off yourself to set a good example. Managers have to be really careful and be on top of that with your employees. Understand who has to take responsibility for certain things and if they are at risk of experiencing burnout. A good manager recognizes when the team needs a break is key. Know when they’ve had a crazy week & let them allocate mental health days accordingly Especially for companies that have nebulous working hours and lack of specific vacation time, ensure that people are taking vacation.

Data Science Hangout | Joseph Korszun, ProCogia | Encouraging People to Learn to Code

We were recently joined by Joseph Korszun, Manager of Data Science at ProCogia. There was a great discussion on mentorship and helping teach people to code. 🤔 How do you encourage people to learn to code? (15:27) ⬢ At every point in your career, you’ve written a formula in Excel so just lending that to translate into you know more usable scripts is helpful. ⬢ It starts with identifying what their determined career path is from their own perspective. Some people want to be more statistics oriented, or more ML engineering oriented. You have to understand what their focal point is. ⬢ Help identify someone’s pain point that they have right now and with that - what’s the quickest way to up-skill them in that? ⬢ Have people do some hands-on labs. This can be more beneficial than watching videos or reading textbooks and allows you to get into the code. You’re going to have errors along the way but that’s ok! ⬢ Let new coders know that it’s okay to google and copy/paste code. This can unblock new coders, so that you don’t have to code everything from scratch. Adapt existing code to your problem. ⬢ You can pair someone with somebody else who has that skillset to help mentor them. ⬢ Remember that junior colleagues often have a lot to teach to senior team members as well. Things are changing so quickly, and there are so many ways to do things. Interns may teach you something new technically and senior colleagues may then mentor them in the soft-skills.

Jorge Valente Hernández Castelán | Algunas formas de ver a Uber en datos: Shiny en acción

*Please note, this meetup was hosted in Spanish. Algunas formas de ver a Uber en datos: Shiny en acción Jorge Valente Hernández Castelán App: https://lnkd.in/evpSjden ¿Cuál es el límite verdadero de la programación en R? Esta pregunta me rondó la cabeza cuando conocí este lenguaje por primera vez hace unos dos años. En aquel momento imaginé que era un lenguaje algo corto de posibilidades, que estaba orientado a estadística y, únicamente, obtener resultados de algunos cálculos. No pude haber estado más equivocado en aquel momento. Cuando comencé a trabajar con Dashboards, probando primero cosas simples como Flexdashboard, me di cuenta de que el presentar información que se encuentra dentro de una base de datos, archivo de excel, etc, no solo se limita a crear estadísticos y un simple gráfico. Las aplicaciones web hechas con shiny no solo presentan información estadística, te cuentan una historia mediante los datos, la cuál puede ser presentada de muchísimas maneras. La aplicación “Uber App” de hecho tiene ese objetivo: Contar mediante estadística y geografía una historia, conocer la lógica y la tendencia de los viajes en Uber dentro de la ciudad de Nueva York, pero ¿Cómo surgió la idea de hacer esta app? En realidad fue una experiencia interesante, ya que un día me encontraba visualizando ejemplos de apps hechas dentro de Python, por lo que una en específico me pareció bastante interesante y en ese momento me hice la pregunta: ¿Es posible realizar algo similar en R? La respuesta a la pregunta anterior fue la siguiente: No solo es posible, también es posible hacerla mejor, mucho mejor. Abstract in English: What is the true limit of programming in R? This question was on my mind when I first came across this language about two years ago. At that time I imagined that it was a language somewhat short of possibilities, that it was oriented to statistics and, only, to obtain results of some calculations. I couldn’t have been more wrong at the time. When I started working with Dashboards, first trying simple things like Flexdashboard, I realized that presenting information found in a database, excel file, etc, is not just limited to creating statistics and a simple graph. Web applications made with shiny not only present statistical information, they tell you a story through data, which can be presented in many ways. The application “Uber App” in fact has that objective: To tell a story through statistics and geography, to know the logic and the trend of Uber trips within the city of New York, but how did the idea of making this app come about? It was actually an interesting experience, since one day I was viewing examples of apps made within Python, so one in particular seemed quite interesting to me and at that moment I asked myself the question: Is it possible to do something similar in R? The answer to the previous question was the following: Not only is it possible, it is also possible to do it better

Data Science Hangout | Mike Smith, Pfizer | Building an R Center of Excellence

We were joined by Mike Smith, Senior Director, Pfizer R&D UK Ltd at the Data Science Hangout - a weekly, free-to-join open conversation for the data science community. If you’d like to join us live, you can add it to your calendar here: rstd.io/datasciencehangout Mike shared with us all that they are building up a Center of Excellence at Pfizer to help teams across the business build reproducible workflows and use analytics tools effectively & efficiently. What led to the creation of the CoE within Pfizer and how could we do something similar? Mike: ⬢ Last year before R/Pharma, we did a poll & found that 1,500+ colleagues had downloaded R. I wanted to service & build up that community to find out what other people are doing and share that. (2:45) ⬢ We’re a very decentralized disparate team, so there are subject matter experts (SMEs) throughout the organization. The Center of Excellence is focused on building connections between SMEs and helping the teams where there isn’t an SME available. ⬢ What we saw was that it’s hard to sometimes get an effective strategy across people in such a big company. We also saw that there were other places within the organization that wanted data science work but they didn’t have an R subject matter expert there. We want to be able to help them solve their problems and set them up with a proof of concept that they can tweak. 33:52 - Ok so how to do this? ⬢ Find out how many people are using the tools and who you could help. ⬢ Be that translator role between the business people who need solutions with the technical side - folks who are building things. Communicate the value: ⬢ We may have a bunch of people trying to write the same function or access the same data. We could solve this problem once and then make that into a package and serve that out to everybody and streamline their workflow for the future. ⬢ There’s a benefit in being able to solve problems strategically. We’re trying to build the lego pieces so that the next time we see a problem like this, we can use that. We can also offer this as a package or via something that allows other people to solve that problem for themselves. Talk to someone who has experience in this, other community builders ⬢ Doug Robinson helped start this at Pfizer because he had set-up something like this at Novartis before as well. Talking with someone who has done this before is really helpful because they have the experience of: who do we need to tell, what do we need to tell them, what’s our purpose for being, who do you have to speak to and convince. That has to be ready to go. Find a champion in leadership: ⬢ We went to the head of Statistical programming and said we’d like to do something like this. Fortunately, she was 110% supportive here. How did they phrase this CoE at Pfizer? ⬢ Check out this description from the job post: https://lnkd.in/g776nYVF Resources shared: Ethan shared: I saw on RStudio blog the other day the {sassy} system for SAS programmer transitioning to R: https://sassy.r-sassy.org/index.html Tatsu shared: For folks that have RStudio Connect and Tableau, there’s now a supported integration https://www.rstudio.com/blog/dynamic-r-and-python-models-in-tableau-using-plumbertableau/ Tatsu shared the Working with IT section of the champion site: https://www.rstudio.com/champion/working-with-it Mike’s Bandcamp: https://mikeksmith.bandcamp.com/ R Consortium Pharma Working Groups: https://www.r-consortium.org/projects/isc-working-groups R in Pharma Conference: https://rinpharma.com/ Upcoming Pharma meetup with Merck: https://youtu.be/RBVqKi3FV30 Question about style guides: Jesus shared: Tidyverse Style Guide: https://style.tidyverse.org/ Jesus shared: One guide overall guide on better clean R code is the contributing.md of the ggplot2 package: https://github.com/tidyverse/ggplot2/blob/main/CONTRIBUTING.md Sam shared: Efficient R Programming book that Colin wrote: https://csgillespie.github.io/efficientR/ Where to find more? ► Subscribe to Our Channel Here: https://bit.ly/2TzgcOu ► Data Science Hangout site: rstudio.com/data-science-hangout ► Add the Data Science Hangout to your calendar: rstd.io/datasciencehangout Follow Us Here: Website: https://www.rstudio.com LinkedIn:https://www.linkedin.com/company/rstudio Twitter: https://twitter.com/rstudio

Data Science Hangout | Erin Pierson, Charles Schwab | Advocating for the Role you Want

We were joined by Erin Pierson, Sr Manager of Trading Operations at Charles Schwab. There was a great conversation about networking within your organization on the hangout with Erin and also tips for the question: How do you have the conversation with your manager that…this isn’t the job that I was hired to do? 🤔 11:57 - ⬢ Talk to people and let them know what you’re capable of doing and what you’re interested in doing. Hopefully you have someone who’s in your corner that will help you get to where you want to be. ⬢ Start talking about what your skills are and what you had discussed your position being. ““You have technically hired me for this job and I’m not doing that job.”” ⬢ You have to have a little finesse about it and can’t be super negative but you can say, “You know, I’m really interested in doing X, Y, Z. I appreciate this job. I’m doing this and I’m learning this but I could also be doing more. I’m interested in doing more.” ⬢ Try phrasing it as what can I do for your leadership, even if it’s really more for you. ⬢ Make your manager aware of where you are and what you want to do. You need to have a good manager to have this happen but in some cases they may even be thinking about hiring someone for that role you actually want to do. ⬢ The bottom line is, if you’re not happy in your job you’re not going to stay in your job. They don’t want you to be unhappy because they don’t want to lose you. If you’re not happy, you’re not going to be doing good work. Be honest and let them know how you’re feeling about it.

Data Science Hangout | Joe Gibson, de Beaumont Foundation | Collaboration Across a Team

We were joined by Joe Gibson, Senior Project Director at de Beaumont Foundation. At the hangout, there was a great conversation on building a code archive database/using snippets ️ 38:16 - Sharing a bit of the conversation below: Stephanie asked: How do you build a code archive database? I’ve worked places with Word documents and need something more user-friendly. Joe: Each time that we create a work product, we log into our database - it creates a new ID for that project and we add some basic information then create a folder for it. We then store it in our structure we have in our network to make it easier for people to find things. In addition to having the library of all our code, we have some folders that have handy code snippets. Steve: We’re developing an internal package for getting data and doing common tasks is a more standard way, which is nice. Nothing too fancy but it streamlines things. Ethan: If you’re using GitHub, Gist is also a great way to share snippets of code. I have a snippet that set up the header/documentation structure for a script. On of the first bits is library(tidyverse) Mike asked: Has anyone developed R snippets and distributed them across a team? I don’t know if people are familiar with the snippets within RStudio but they are cool because you can use template frameworks and it jumps you to the next thing you need to tailor for your own situation. It’s essentially a function. Tatsu shared: https://lnkd.in/gwWCB3T2 Javier: These are super helpful, Mike. I recently learned about them and was shocked. I have all kinds of snippets for myself and my team now. Jordan: I’ve saved snippets inside a core package and have a function that updates your RStudio snippets. Saved a snippet update gist here: https://lnkd.in/gEcmNViN requires a snippets folder in your package/inst. You can have this.onLoad() if you’re feeling lucky Resources shared: ◘ Rachael shared the new champion site: https://lnkd.in/gaHt_8Br ◘ Jen & Michelle shared the National Syndromic Surveillance Program Community of Practice: https://lnkd.in/gHE3C94s ◘ Joe shared Harold’s GitHub for NSSP projects: https://lnkd.in/gFRsezTM ◘ Joe mentioned, Mozilla Foundation to ensure the internet remains a public resource that is open and accessible to us all. https://lnkd.in/gbvdQXwH ◘ Rachael shared AI Inclusive https://lnkd.in/gt8cQUUX ◘ Cris shared Fairlearn to improve fairness of AI systems:: https://fairlearn.org/ ◘ Angela shared openscapes, helping teams develop collaborative practices that are more reproducible, transparent, inclusive, and kind: https://lnkd.in/gs-6_-ZA Where to find more? ► Subscribe to Our Channel Here: https://bit.ly/2TzgcOu ► Data Science Hangout site: rstudio.com/data-science-hangout ► Add the Data Science Hangout to your calendar: rstd.io/datasciencehangout Follow Us Here: Website: https://www.rstudio.com LinkedIn:https://www.linkedin.com/company/rstudio Twitter: https://twitter.com/rstudio

Santiago Rodriguez | Intro to functional data analysis | RStudio Meetup

Energy Meetup - Intro to functional data analysis Presented by Santiago Rodriguez 2:49 - Start of talk 12:15 - First Q&A point 23:23 - Second Q&A point 31:56 - Third Q&A point 40:44 - Final Q&A point Abstract The focus of this talk is to introduce functional data analysis (FDA) and to showcase some of its applications in the utility space. A primary source of data in a utility are meter reads. This data is periodic and appears discrete, but energy consumption is continuous, which makes meter reads a perfect use case to apply FDA. The talk will highlight two applications: load profiles and segmentation. The talk will be non-technical - no math or code - because the goal of the talk is to persuade you to investigate FDA on your own. Speaker Bio Santiago is a data scientist in the marketing department at Consumers Energy, a Michigan-based, public utility. He focuses on data engineering, data science, and MLOps. Santiago has about a decade of experience working in the analytics space across energy, aviation, automotive, and contact centers. He has a bachelor’s in finance from Florida State University and a master’s in statistics from Texas A&M.

Brad Lindblad | Professional Financial Reports with {rmarkdown} | Posit

GitHub: https://github.com/bradlindblad/pro_reports_talk Abstract: With finance there will always be a need for reports, and as long as there’s a need for reports, there will be R users who want to create them as lazily as possible. R Markdown lets us create incredibly customized and branded reports that can run automatically each month or day or whatever, and it all starts with the wonderful parameterizing features of R Markdown. In this lightning talk, we will work through a practical example of creating an income statement for a group of theoretical office branches. You will learn how to make a parameterized R Markdown report, organize your R Markdown files and even create a custom cover letter, all in R. Bio: Brad Lindblad is a data scientist located in Fargo, North Dakota. He is author of the tidyUSDA and schrute R packages, and specializes in geospatial data science and risk modeling.

Data Science Hangout | Kristi Angel, Stitch Fix | How to Break into Data Science

On March 10th, we were joined by Kristi Angel, Data Scientist - Experimentation @ Stitch Fix. This week featured a lively discussion on breaking into data science: Try to get around the applicant tracking systems by networking - we can call it something different though. Utilize LinkedIn as a professional social media. Find people who are generating content that you find interesting. Engage and people will start to know who you are by your comments and feedback. This will help you build a reputation for yourself. Try to connect directly with the hiring manager. There are a lot of hiring managers advertising for roles on LinkedIn right now. Take a look at your resume and see if you can get some reviews from peers you trust and see if there’s a way that might be more effective. Your resume needs to tell your story in less than a 5 minute glance. A lot of us mentioned we would be willing to help review here - let’s think of ways to connect people through this group too:) For some people hitting HR roadblocks, where large businesses have decided that there are minimum requirements for education and experience and there is absolutely no budging from it - looking at smaller companies without those rules has helped lots of people I know. On the topic of interviewing and hiring people with degrees vs no degrees or not a relevant degree ️ A lot of us shared in the chat that we have different degrees than the job we’re doing today:) Looking past the degree is a really good idea in many cases because you need diversity of thought and background. If you want the company as a whole to have empathy for customers, it’s important to have a really varied set of life experience backgrounds. We still acknowledge, it can be hard because the degree and experience gives a little bit of a certification, especially for junior people. In startups especially, the time spent hiring can be a lot of drain on the organization so degrees are often used to quickly filter. If you’re on the side of the company interviewing, something that can also help is to make sure that all interview loops have a diverse representation. Links shared: Frank shared: Kahnaman’s book Noise has some great frameworks for interviewing and how we make decisions on candidates. One example, stack rank your candidates instead assessing each individually because (people) are typically bad at that: https://readnoise.com/ Melody’s team is hiring several Data Scientist positions and a Data Architect position.

Data Science Hangout | Stephen Bailey, Whatnot | From Academia to Industry

We were joined by Stephen Bailey, Data Engineer at Whatnot and former Director, Data & Analytics at Immuta at the Data Science Hangout. A few topics from the discussion: being the first data scientist working with real-time data bringing data science skills to data engineering getting people to feel ownership of data 49:43 - Towards to end of the hangout, there were a lot of thoughts on moving from academia to industry. Tatsu asked: As a fellow recovering academic, I’d love to hear your views of where we are in terms of the process for PhDs to go into industry in data related role? In psychology, there was minimal visibility into how to apply my skill set. A few thoughts from the discussion: ‣ With a PhD program, it’s almost like you have a relationship with the field and you’re very invested in the research. You’re part of the scientific community. One of the things that’s very jarring about leaving, is that it feels like a divorce - severing that relationship and that community. It is almost two different worlds. ‣ If anyone’s thinking about transitioning or doing something similar, talking to people and building relationships before that transition can really help. ‣ Intentionally think about branding yourself. ‣ The biggest thing in industry is that you can’t fall in love with a problem. It makes finding a job much harder. You have to fall in love with your position in some way, how you are solving problems. Apply the mindset of a scientist into this business context. ‣ The skillsets that everyone’s learning in graduate school - no matter what the subject area is, are very helpful. My biggest advice would be don’t be afraid to reach out to people (whether on LinkedIn or in community events.) Most people are very willing to talk to you about what their journey was no matter where they’re at in their career. Once you realize that, you will see that your room is much bigger. ‣Finding a mentor outside academia is really helpful. ‣ Certain departments within universities do a really nice job connecting with industry with the community and have great collaboration. How can that carry over to other institutions? How can companies better connect with colleges to help them understand how they can help more students?

George Mount | R for Excel Users - First Steps | RStudio Meetup

Abstract: Excel’s built-in programming language has served as an entry point to coding for many. If you’re a data analyst steeped in Excel, chances are you could also benefit from learning R for projects of increased scope and complexity. This presentation serves as a hands-on introduction to R for Excel users: How R differs from Excel as an open source software tool How to translate common Excel concepts such as cells, ranges, and tables to R equivalents Example use cases that you can take and apply to your own work How to enhance Excel and Power BI with R By the end of this presentation, you will have a clear path forward for building repeatable processes, compelling visualizations, and robust data analyses in R. Speaker Bio: George Mount is the founder of Stringfest Analytics, a consulting firm specializing in analytics education and upskilling. He has worked with leading bootcamps, learning platforms and practice organizations to help individuals excel at analytics. George regularly blogs and speaks on data analysis, data education and workforce development. He is the author of Advancing into Analytics: From Excel to Python and R (O’Reilly). Link to George’s white paper “Five things Excel users should know about R”https://stringfestanalytics.com/five-things-r-excel/ Working group sign-up for those interested! Within many organizations Microsoft Excel is a preferred tool for working with data for non data analytics users. In order to build a data driven organization, source data and analytical models must be accessible to all data users (technical and non-technical) within their preferred tool. Let’s rally the R community to welcome Excel users into our data driven culture by building an Excel add-on to access data and models available within RStudio.

Shiny Usage Tracking in Posit Connect

🤔 Who actually used my Shiny app and for how long? ↗️ Is viewership increasing? Did my CEO use it?! Did you know? Posit Connect can record event-style usage information which is intended to answer questions like this and is accessed via the Posit Connect Server API. Please note: during the meetup you can ask questions here anonymously as well: rstd.io/connect-meetup-questions We will walk through several examples for getting started with the Posit Connect usage data designed to help you answer questions like: Who is visiting my content? What reports are most common? Has viewership increased over time? During/after the meetup, you can use the GitHub repo to create the dashboard in your own Connect environment as well and schedule the report to be distributed through email (with inline graphics). The goal for this code is that it is generic enough so that you can copy/paste it into your own R session and run it successfully. In order for the code to work in your environment, you need two pieces of information unique to your enterprise: Posit Connect’s server path A Posit Connect API Key We’d love to hear your feedback and learn how you have taken this API and created dashboards for your own organizations as well.

Data Science Hangout | Katie Schafer, Beam Dental | Building a Data Science Portfolio

We were recently joined by Katie Schafer, VP of Advanced Analytics at Beam Dental, to discuss the most important things going on with data science leadership. Great tips & resources shared for this question: What can I do to be able to present my skills and build a portfolio if I’m not able to share my work? Many people expressed that they are in this position. Katie: Is it possible to simulate something akin to some of the data you would use? For project portfolios, submitting the actual work is not something that I’ve seen often. In interviews, you need to be able to discuss the work. Describing the projects is really tough because you want to say something meaningful but you don’t want to be too specific. Having a role play conversation with yourself on questions you’re getting & practicing answers that are more generalized can be helpful. Take one specific problem, translate that to an abstract problem that you tackled with statistics and programming. Javier: I’ve been in a similar boat. There’s a package called synthpop: https://lnkd.in/g_paFGNB, which helps take actual data points and simulates them to make a completely synthetic data set. When I was interviewing for my job now I built a shiny app that I deployed to a free shinyapps.io. I styled the whole app to be consistent with their brand. I don’t attribute that alone to getting the job, but the interviewers were super impressed. The ability to change out the theme is so easy, so for anyone who’s trying to get a job this could be an easy way for you to have something that you can change whenever you interview with a new company. Rick: If you’ve ever worked with a designer - they have a template and they’re not just creating everything from scratch. If you have a nicely organized project as a data scientist, you’re showing your skills as a software engineer. Zac: I do a lot of personal projects because I don’t use R at work. For these projects I focus the topic on what skills I want to show off. I’m looking to start my career, so I write a blog & include reasons why I did something. I think this makes it a lot easier to share what I’ve done https://lnkd.in/gzhwuCqw Libby: For me with portfolio work, it’s been difficult because sometimes my contributions are one algorithm inside a larger shared project, so I stick to descriptions, talking about what I did and why I did it, what the result was. Larry: I describe the topic and present the deck. Sometimes I just make fake data, but talk about the steps I took. Katie: Some of my richest connections have also come from speaking. R-Ladies has been a great starting point for that. A lot of meetups have gone virtual so you can now join a chapter even if you don’t have one in your city. Jiwan: Maybe start with a 5 min lightning talk with a topic you’re excited about! Other resources shared during the chat: Prabha: Technical debt in ML systems - https://proceedings.neurips.cc/paper/2015/file/86df7dcfd896fcaf2674f757a2463eba-Paper.pdf Rachael: R community explorer app: https://benubah.github.io/r-community-explorer/rugs.html Javier: GitHub for the {bslib} app, feel free to clone as you see fit: https://github.com/JavOrraca/bslib_demo_shiny Jobs shared during the chat: Niklas: Several data science roles at my company (sustainability SaaS). 2 data engineers, 1 data analyst, 1 data scientist - https://higg.com/careers/ Jill: We are hiring for a Data Analyst role here at Viemed.

Data Science Hangout | Asmae Toumi, PursueCare | Data Science Team Culture

We were recently joined by Asmae Toumi, Director of Analytics at PursueCare, to discuss the most important things going on in data science leadership. There was a great discussion during this session starting from the question, “Is it ok to say that we are data analysts and data scientists interchangeably?” Javier: Some of the best data scientists have the title of financial modeler or senior actuary. Some of the best programmers and package developers I know, have the title of data analyst. I think it depends on the organization. We have these guidelines that are more of an ideological function of a data scientist vs data analyst but I think in practice it’s all over the place. Asmae: Jacqueline Nolis and Emily Robinson have good thoughts about this: https://jnolis.com/book/ (Short rules from the book I saw: An analyst creates dashboards and reports that deliver data. A decision scientist creates analyses that produce recommendations.) Mike: I think to anyone that is OUTSIDE of Data Science / Data Analytics, the distinction is not worth discussion. If you want funding you’re a Data Scientist. If you HAVE funding it doesn’t matter. Frank: No right answer (DS vs. DA)… only different ways to think about it at different times in different contexts. Jordan: I’ve usually been working in a ““Science”” (science/research) domain at companies. To this end, I’ve sort of been the ““Data”” Scientist, maybe not ““Data Scientist”” What about business intelligence? Asmae: I use data analyst and data scientist interchangeably. I think there is a meaningful difference there between a business analyst and a data scientist. What about data engineering? Asmae: We have 3 data engineers. Data scientists all want a data engineer. As a healthcare company, it’s complex to deliver the care that we do. With that complexity comes interfacing with different data vendors - different data sources so it’s really important to invest in data engineering so the reconciliation of that data across the many vendors is ensured. Data quality is also super important. Bryan: Data engineering is the foundation of it all — need a solid data engineer to do anything Falak: Data scientists understand the distribution of the data and figure out what class of algorithms would be suitable to handle a particular problem. Data engineers can solve the optimization problem.

Custom themes may even be created interactively in real-time. Also provide easy access to pre-packaged Bootswatch themes. Make upgrading from Bootstrap 3 to 4 (and beyond) as seamless as possible. (Shiny and R Markdown default to Bootstrap 3 and will continue to do so to avoid breaking legacy code.) Serve as a general foundation for Shiny and R Markdown extension packages. (Extensions such as flexdashboard, pkgdown, and bookdown already fully support bslib’s custom theming capabilities.)

Barret Schloerke || Maximize computing resources using future_promise() || RStudio

00:00 Introduction 01:45 Setting up a multisession using the future package 02:05 Simulation using two workers 04:14 Simulation using 10 workers 05:20 What happens when we run out of workers? 05:35 How Shiny handles future processes like promises 07:16 Introduction to future_promise() 07:45 Demo of the promises package 09:21 Setting the number of workers 10:40 Demo of processing without future_promise() 14:11 Wrapping a slow calculation in a future() 14:53 Demo of processing using Plumber 16:25 Considerations on the number of cores to use 17:21 What happens if we run out of workers? 19:44 Decrease in execution times using future_promise() In an ideal situation, the number of available future workers (future::nbrOfFreeWorkers()) is always more than the number of future::future() jobs. However, if a future job is attempted when the number of free workers is 0, then future will block the current R session until one becomes available. The advantage of using future_promise() over future::future() is that even if there aren’t future workers available, the future is scheduled to be done when workers become available via promises. In other words, future_promise() ensures the main R thread isn’t blocked when a future job is requested and can’t immediately perform the work (i.e., the number of jobs exceeds the number of workers).

Behind the scenes, Shiny builds a reactive graph that can quickly become intertwined and difficult to debug. reactlog provides a visual insight into that black box of Shiny reactivity. After logging the reactive interactions of a Shiny application, reactlog constructs a directed dependency graph of the Shiny’s reactive state at any time point in the record. The reactlog dependency graph provides users with the ability to visually see if reactive elements are: Not utilized (never retrieved) Over utilized (called independently many times) Interacting with unexpected elements Invalidating all expected dependencies Freezing (and thawing), preventing triggering of future reactivity There are many subtle features hidden throughout reactlog. Here is a short list quickly describing what is possible within reactlog: Display the reactivity dependency graph of your Shiny applications Navigate throughout your reactive history to replay element interactions Highlight reactive family trees Filter on reactive family trees Search for reactive elements You can read more about reactlog here: https://rstudio.github.io/reactlog/articles/reactlog.html And you can learn more about Shiny here: https://shiny.rstudio.com/ Got questions?

Data Science Hangout | Prabha Thanikasalam, Flex | Calculating ROI with the Business

The Data Science Hangout is a weekly, free-to-join open conversation for current and aspiring data science leaders. rstudio.com/data-science-hangout We were recently joined by Prabha Thanikasalam, Senior Director, Analytics and Supply Chain Solutions at Flex, to discuss the most important things going in data science leadership. There was a great conversation live and in the chat that followed this question. 𝐇𝐨𝐰 𝐝𝐨 𝐲𝐨𝐮 𝐬𝐭𝐚𝐲-𝐟𝐨𝐜𝐮𝐬𝐞𝐝 𝐰𝐡𝐞𝐧 𝐰𝐨𝐫𝐤𝐢𝐧𝐠 𝐨𝐧 𝐝𝐚𝐭𝐚 𝐩𝐫𝐨𝐣𝐞𝐜𝐭𝐬? (From two sides: when learning data science and also when working on projects for the business) Think about it as a marathon, not a sprint, you won’t be an expert in 6 months or a year. Build a good foundation over time by spending 45 minutes a day learning something. Don’t keep your email inbox open all the time. This won’t work all the time, but it helps! Try to separate the time you devote to learning new skills rather than “learning while doing” all the time. This can allow you to work faster with imperfect solutions and set aside learning a better way of doing it in dedicated time. Although it’s important to keep delivering quality analysis and product, it helps me move away from perfectionist tendencies. Getting “side-tracked” isn’t necessarily bad - sometimes we’re asked to solve the wrong question and find that out half way through Give yourself a deadline, or if you’re working with the business meet with them to discuss the success criteria and deadlines Encourage teams to explore rabbit holes and not be mindless “task completers.” Some of the best insights come out of curveballs we explore. Curiosity is also key to being a great data person Try using a pomodoro timer to keep focused time Check out Jacqueline Nolis & Emily Robinson’s book/companion podcast, “Build a Career in Data Science”, which talks about using projects as a motivator for learning new skills. Sometimes, it’s better to start with a problem you want to solve rather than start with a skill you want to learn! When starting out, try to use code as frequently as possible, and also find a project you can get really excited about. Passion can help with the late nights and tying in some of the side track thoughts to one topic or outcome. It’s helpful to realize there are still plenty of skills that require dedicated time to do more focused learning to exclusively understand the math, methodology, and technology. For example, with Natural Language Processing, starting with the technology and then moving onto the documentation can be an order that keeps you motivated.

Data Science Hangout | Ian Anderson, Philadelphia Flyers | Moving into Leadership & Managing a Team

The Data Science Hangout is a weekly, free-to-join open conversation for current and aspiring data science leaders. posit.co/data-science-hangout We were recently joined by Ian Anderson, Director of Hockey Analytics at the Philadelphia Flyers, to discuss the most important things going in data science leadership. One of the topics that there were a lot of thoughts on during this hangout was balancing that shift into leadership and maintaining technical skills. Question: 𝐀𝐬 𝐲𝐨𝐮 𝐦𝐨𝐯𝐞 𝐮𝐩 𝐭𝐡𝐞 𝐥𝐚𝐝𝐝𝐞𝐫 𝐢𝐧𝐭𝐨 𝐥𝐞𝐚𝐝𝐞𝐫𝐬𝐡𝐢𝐩 𝐚𝐧𝐝 𝐦𝐚𝐧𝐚𝐠𝐢𝐧𝐠 𝐚 𝐭𝐞𝐚𝐦, 𝐚𝐫𝐞 𝐲𝐨𝐮 𝐰𝐨𝐫𝐫𝐢𝐞𝐝 𝐚𝐛𝐨𝐮𝐭 𝐥𝐨𝐬𝐢𝐧𝐠 𝐲𝐨𝐮𝐫 𝐭𝐞𝐜𝐡𝐧𝐢𝐜𝐚𝐥 𝐜𝐨𝐝𝐢𝐧𝐠 𝐬𝐤𝐢𝐥𝐥𝐬? Here are a few of the thoughts shared live from Ian and the community: You make time for things that are important to you. If exercise and health is important to you, you make time for it. If coding is something that you want to continue to maintain, you can find the time for that. Think about blocking designated focus time to do your individual work Be curious. Office hours as a manager to answer questions from your group can also be an opportunity to learn new things/packages/methods together Organize opportunities for the team to share any topics that they would like (coding, techniques, etc.) In sharing topics, you can also try limiting the time to ~4min to share. Two benefits of this fast moving, high energy meeting: 1. People will inspire each other with passion and creativity 2. The team gets to practice communicating their ideas with precision. Becoming more comfortable with what it means to lead people, it’s about enabling them to be really successful. If you measure your success by other people’s success, it can also help rationalize that. If you can chop down barriers for them, then they will be more successful so that means the technical time I sacrifice enables them further. It’s still very relevant to keep your skills at some type of level just for street cred in your team. Bringing in new people, if you can talk that language it just really helps your team and you can have those conversations." ► Subscribe to Our Channel Here: https://bit.ly/2TzgcOu Follow Us Here: Website: https://www.rstudio.com LinkedIn: https://www.linkedin.com/company/rstu … Twitter: https://twitter.com/rstudio

However, they’re often stuck in data scientists’ local computing environments. Collaborating can be difficult and sharing can be tedious. To live up to their fullest potential, data science teams need a way to scale their development securely and efficiently — while providing stakeholders easy access to their output and visualizations. RStudio Team, made up of RStudio Workbench, RStudio Connect, and RStudio Package Manager, brings everything together to help data scientists create, reproduce, and share insights from their Jupyter Notebooks. Let’s dive into a real-life example by exploring data from NASA’s Center for Near-Earth Objects (NEOs). Daniel Petzold walks us through his data analysis and reporting. Want to explore the report yourself? Check out the published report on RStudio Connect here. https://colorado.rstudio.com/rsc/space-tracker/space_tracker.html On RStudio Workbench, you have a choice of editors: the RStudio IDE, JupyterLab, Jupyter Notebook, or VS Code. Choose your preference. From here, you can explore your dataset, embed HTML directly in your document, create visualizations, and more. Once you’ve run your analyses and created insightful visualizations, you want to be able to share them with your team. RStudio Workbench allows you to publish to RStudio Connect, the content platform from RStudio. You have multiple options: push-button deployment from Jupyter Notebook or using terminal commands from JupyterLab. It’s not enough to publish your work. Once on RStudio Connect, you can share with end-users. Make your analysis accessible to specific users or more generally with different authentication measures. In addition, you can schedule the document to run at a certain time and send out an email with refreshed data. Click the links below to learn more about these offerings.

The gt philosophy: we can construct a wide variety of useful tables with a cohesive set of table parts. These include the table header, the stub, the column labels and spanner column labels, the table body, and the table footer. It all begins with table data (be it a tibble or a data frame). You then decide how to compose your gt table with the elements and formatting you need for the task at hand. Finally, the table is rendered by printing it at the console, including it in an R Markdown document, or exporting to a file using gtsave(). Currently, gt supports the HTML, LaTeX, and RTF output formats. The gt package is designed to be both straightforward yet powerful. The emphasis is on simple functions for the everyday display table needs. You can read more about gt here: https://gt.rstudio.com/articles/intro-creating-gt-tables.html And you can learn more about Shiny here: https://shiny.rstudio.com/ Got questions?

Ralph Asher & Laura Darby Rose | R in Supply Chain Management | RStudio

Two talks! 3:24 - Start of meetup 3:24 - Intro to Supply Chain Design - Ralph Asher 33:38 - Forecasting Demand with R - Laura Darby Rose Intro to Supply Chain Design - Ralph Asher Abstract: COVID-19 has moved supply chain management from the back office to front-page news. And along with it, the discipline of supply chain design – the strategic evaluation of deciding where to locate manufacturing sites, warehouses, and other supply chain facilities – has gone from a little-known niche to a C-suite priority. In this talk, I will introduce the field of supply chain design to the R community. Drawing upon my decade of experience in supply chain design and R, I will give a short example of how to design a warehouse network to support future customer need. This example will be drawn directly from my experience in the corporate world and my consulting business. Speaker Bio: Ralph Asher is the founder of Data Driven Supply Chain LLC, a Minnesota-based consulting firm that uses data science and AI to evaluate, design, and optimize supply chains. ( www.datadrivensupplychain.com ) Prior to founding Data Driven Supply Chain, Ralph worked as an Operations Research Scientist in corporate supply chain functions for 8 years at Target, designing e-commerce supply chain networks, and at General Mills, designing warehousing networks. Ralph has used R for supply chain analytics for a decade and can be reached at ralph@datadrivensupplychain.com or via LinkedIn. Forecasting Demand with R - Laura Darby Rose Abstract: Over the course of about a year, Mallinckrodt Pharmaceuticals’ Specialty Generics division replaced an expensive SaaS (Software as a Service) with an R script and alternate forecasting process. Using an RStudio Enterprise solution, they have found a more flexible and cost-effective way to forecast demand and analyze data with R. This discussion will detail the process of replacing a SaaS with R, as well as challenges and next steps in the project. Speaker Bio: Laura Darby Rose is Manager of Demand at Mallinckrodt Pharmaceuticals, where she is responsible for statistical forecasting, forecast visualization, and forecast accuracy measurement for the Specialty Generics division. She has a M.A. in Economics from the University of Missouri-St. Louis, and enjoys using R and SQL for time-series analysis, creating Shiny apps, and data wrangling/cleaning. Are you a data scientist or data analyst working in supply chain management? Are you interested in joining a group of fellow practitioners and taking a leadership role in developing and promoting open source solutions in your field? Join us! At this meetup, we also proposed the formation of a community working group focused on developing and popularizing open source solutions for data scientists and analysts working in supply chain management. We’d love to start by creating a home – initially a website – which hosts resources for supply chain data scientists. More to come. Form to be part of the working group: rstd.io/supply-chain-community-org

An inclusive solution for teaching and learning R during the COVID pandemic

The COVID pandemic has shaken our teaching and learning approaches in many different ways all over the world. Nonetheless, it has also provided opportunities for bringing creativity into the classroom. In this talk, I will discuss how I have used RStudio Cloud in my teaching during the pandemic and how I capitalized on the opportunities that RStudio Cloud offers to deal with the crucial issues of software installation. Introducing RStudio Cloud in the units has allowed me to work effectively in an online environment to engage, motivate and empower students through their learning process while removing the troubles and hurdles of software installation which is generally particularly challenging in first-year cohorts without prior coding experience. I used RStudio Cloud in a data science introductory unit at Monash University and as a tool to present the usage of R and RStudio for reproducible reporting in another unit on Reproducible and Collaborative Practises. In the latter, I introduced RStudio Cloud during the first few weeks to get the students up to speed before transitioning to using R and RStudio Cloud in their own local machines while using the command line interface, Git, and GitHub as a version control tool for reproducible reporting. I will also discuss how I organized and managed the unit’s RStudio Cloud account so that my research associates were also an integral part of the unit delivery to ensure the success of the units.

RStudio Connect | Cut down on the grunt work. Deliver insights more effectively with RStudio

You built a great data science product. Something your stakeholders want and have been asking for. But operationalizing that data product is hard. How do you deliver it to interested stakeholders in the format that they want with the specific insights that they need? And what if you need to deliver your data products to multiple stakeholders, all with slightly different requirements? How do you make sure that the data product is always up to date? And when the data is updated, how will your stakeholders know? This is why we built RStudio Connect. RStudio Connect is the best way for data science teams to curate and share data products with their organizations. It comes with all of the bells and whistles that professional data science teams typically need to turn their analyses into value. In this live event, we’ll do a deep dive into one of RStudio Connect’s most powerful features: scheduling and distributing data science products. This feature enables data science teams to take all of their data science products and insights and deliver them to everyone that needs them to make decisions. Always on time, in the format that they want, and as efficiently as possible. Specifically: we will show how a data scientist can deploy an R Markdown or Jupyter Notebook to RStudio Connect, then schedule the data product to update and get delivered to interested stakeholders. All without the traditional work associated with updating data pipelines and updating reports. Put simply: we think RStudio gives data scientists, data engineers, and business users superpowers, and we can’t wait to show it off to you

Leveraging the Cloud for Analytics Instruction at Scale: Challenges and Opportunities

Data science and programming languages like R and Python are some of the most in demand skills in the world. Students interested in analytics and professors facilitating curriculums deserve to use industry-leading tools to acquire these skills. However, it’s challenging to enable this experience in an educational setting, especially at scale. The traditional tools to facilitate learning analytics simply aren’t great. Students and professors often spend way too much time troubleshooting systems and software, things that are a complete waste of time and detract from the learning experience. Additionally, there are seemingly endless IT hurdles and requirements. That’s part of the reason we created RStudio Cloud, a brilliantly simple but powerful solution for teaching and learning analytics, especially at scale. RStudio Cloud solves many of the technical and financial challenges associated with teaching analytics. It’s also a joy to use for professors, students, and IT administrators. In this presentation, Dr. Brian Anderson will discuss the challenges and opportunities associated with leveraging the cloud to deliver analytics instructions at the undergraduate and graduate levels at scale. Our hope is that you walk away inspired to think about ways you can leverage RStudio and the Cloud to enhance your students’ experiences with learning analytics.

GA Tech || “Communicating with 8 Million People through Shiny” || Posit

Georgia Institute of Technology faculty, scientists, GIS specialists, and graduate students launched a tool that provided real-time, localized information on the estimated risk of COVID-19 exposure by attending an event. In talking with their team it was clear that their empathetic perspective of the audience and communication-focus helped successfully share their insights with event planners, policy makers, various news outlets and individuals - adding up to ultimately over 8 million unique users around the world. Lessons learned from the GA Tech team about their experience building the COVID-19 Event Risk Assessment Planning Tool can apply to visualizations across many different industries and use cases - whether you are communicating to a handful of executives at your company or out to the world: As a Shiny developer, make sure that you have a specific question in mind. What is the problem that you have that your app is helping them solve? Think about who your audience is going to be and what they would use this for. For the COVID-19 Event Risk Assessment Planning Tool, this question was “what is the risk level of attending an event, given the event size and location?” View your audience through a lens of empathy. Think about metrics that people can really get a grip on and visualize. For example, the risk of attending a local event with 100 people in your own town vs. communicating this as cases per 100,000 people. If you want to communicate something that’s critical to the public, put it in the right terms. Balance the straightforwardness of your visualization. You don’t have to anticipate every single question. With every feature or piece of information included, ask yourself if this supports your overall point? Importance of continued communication. Keep the lines of communication open with your users. If you share a visualization, make sure that people have a clear way to contact you (email, Twitter, LinkedIn) with questions or feedback. Their team made an intentional effort to be available for local news particularly. They were responsive to the kinds of decisions people were making and adjusted the app to match their needs with event sizes for example. Check out their Shiny application here: https://covid19risk.biosci.gatech.edu/ Read the related blog post here: https://blog.rstudio.com/2021/09/14/how-do-you-use-shiny-to-communicate-to-8-million-people/

RStudio Cloud | Viewing Learning Work | Instructor View

As an Admin (or Moderator) of your course space, you and your fellow instructors have access to all projects in your space. You can open student projects from any projects listing, or to see all the projects of a given student, go to their profile page by clicking on their name from the Members page. Note that if you do open a student’s project while they also have it open, they will be temporarily disconnected from the project. You can also view how much time your students have spent using Cloud. Simply visit the Usage area of your space, where you can see aggregate usage data for the entire class, or for an individual student and their projects. ABOUT RSTUDIO CLOUD: RStudio Cloud is a lightweight, cloud-based solution that allows anyone to do, share, teach and learn data science online. Analyze your data using the RStudio IDE, directly from your browser. Share projects with your team, class, workshop or the world. Teach data science with R to your students or colleagues.

RStudio Cloud | Tuning Resources | Instructor View

By default, each project is allocated 1 GB of RAM and 1 CPU, and can execute in the background for up to 1 hour. If your plan allows it, you can increase the memory, CPU or background execution time allocated to a project. To do so, open Project settings, go to the Resources panel and adjust the allocation. Note that copies of a project will inherit its resource settings. However, the effective allocation for the copy will be limited by the maxiumum allowed by the account that “owns” the new copy. The usage hours consumed by a project in a given amount of time depend on the resources allocated to the project, according to the following formula: (RAM + CPUs allocated) / 2 x hours. On disk, each project is allocated up to 20GB for its files, data, and packages. The maximum size of a file that can be uploaded to a project is 500MB.

RStudio Cloud | Troubleshooting | Instructor View

Relaunch Project If you are working on a project, and it fails to load or becomes completely unresponsive, you can relaunch the project. Depending on the underlying problem, relaunching the project may fix it and let you continue. Allocate Additional Memory memory-gaugeRunning out of memory while working on a project may be the cause of a variety of errors. The project memory gauge will give you an idea of what percentage of available memory your project is currently using. The gauge updates roughly every ten seconds, so it may not show the exact usage at the current moment. Note that reclaiming unused memory is controlled by R and the operating system - you may see uncanny fluctuations in the gauge as the system manages memory.

RStudio Cloud | Setting Up a Base Project | Instructor View

You can make all projects in a space begin with a default set of files and packages. You do this by defining a Base Project for the space. Create a new project and add any packages or files you want all projects created in the space to start with. Set the project’s access so that everyone in the space can view the project. Go to the Space Settings page and select the project as the Base Project. Once you select a project as your Base Project, it will no longer be included in the projects listing for the space. To access it, choose the Edit command from the Space Settings page. Changes to the Base Project are not retroactive. Changes will not be applied to any projects already created - the changes will only apply to future projects created via the New Project action.

RStudio Cloud | Roles | Instructor View

Each member of a space is assigned a role to determine what they are able to do within the space. The available roles are: Admin: can manage users, view, edit and manage all projects and view space usage data. Moderator: can view, edit and manage all projects, and view space usage data. Contributor: can create, edit and manage their own projects. This is the default. Viewer: can view projects shared with everyone in the space. A viewer cannot create or save copies of projects. Members are assigned an initial role when they are invited to or join a space, but roles can be changed by an Admin at any time. When you invite an individual member to a Invitation Required space, you set the initial role in the Add Member dialog box. When someone joins via a sharing link, their initial role is set to the current Initial Role setting in the members options panel. Admins can update a user’s role via the role selector in the members list. Changing permissions lets you fine-tune the Contributor and Viewer roles. The permissions are: Contributors can see the members list: enables Contributors to see who can access the space. Contributors can make their projects visible to all members: enables Contributors to share their projects with everyone in the space. Contributors can change project resources: enables Contributors to change RAM and CPU settings on their projects. Viewers can see the members list: enables Viewers to see who can acess the space.

RStudio Cloud | Reusing a Workspace | Instructor View

One approach to reusing a space is to remove the current cohort of students from the space, and reuse the same space with the next cohort. If you are an Admin of a space, you can remove any member from that space. Go to the Members area of the space. For the member you would like to remove, press the Delete icon. You will be prompted to confirm that you would like to remove them from the space, and to choose whether to leave their projects behind in the space, or move them to their personal space. You can also remove members programatically via the Cloud API using the rscloud package. Another option is to create a new space from your current course space using the Copy Space action. If you’d like to re-use materials from a space, e.g. to teach a new cohort of students, use the Copy Space command. All projects shared with everyone in the original space will be copied over to the new space. Members of the original space are not copied over - you will be the only initial member of the new space.

RStudio Cloud | Project Types | Instructor View

A project is the fundamental unit of work on RStudio Cloud. It encapsulates your R code, packages and data files and provides isolation from other analyses. If you are familiar with projects in the desktop RStudio IDE, an RStudio Cloud project is the same thing, plus some additional metadata for access and sharing. To create a new project from scratch, simply press the New Project button from the Projects area. Your new project will open in the RStudio IDE. To create a new project from an existing git repository, press the down arrow on the right side of the New Project button, and choose ‘New Project from Git Repo’ from the menu that appears. Note that your git credentials need to be entered each time you create a new project and are only cached for 15 minutes by default. To create a Jupyter Project, press the down arrow on the right side of the New Project button, and choose ‘New Jupyter Project’ from the menu that appears. A new Jupyter project will be created and deployed. Once deployed, you will see the Jupyter hub tree view with a welcome.ipynb notebook that contains information about getting started with Jupyter.

RStudio Cloud | Inviting Co-instructors and Teaching Assistants | Instructor View

After creating a space, go to the Members area to manage its membership. You can add members to your space in three ways: To add members one by one, choose the Invitation Required option, and send invitations to each person you’d like to add to the space via the Add Member button. Note that for security reasons, the invitation is good for 7 days from the time that it is sent. To allow many people to join the space, choose the Sharing Link option, copy the sharing link and then share that link with all the people you’d like to join the space, either via an email or by posting the link on a web page. Keep in mind that anyone with that link will be able to join your space. If you would like to disable a link you previously shared, choose Reset Sharing Link; this will prevent any additional people from joining the space using that link. Space membership can also be managed programatically. See API Access from R in the Advanced Topics section below for details. Note that you can switch the access option at any time - a common approach is to initially set the access option to Sharing Link, post the sharing link, then after all the people you want to join the space initially have done so, switch access to Invitation Only. The original sharing link will no longer allow additional people to join the space, but you can add any new members individually.

RStudio Cloud | Invite Learners | Instructor View

As you did to invite your co-instructors, go to the space’s Members area to invite your students to your course space. The easiest approach is to enable access via a sharing link. Click on the Sharing link option in the Access section Set the Initial Role to Contributor Click on the Copy Sharing Link action You can then distribute the sharing link to all your students via a course web page or email. Once all your students have joined the space, you can either reset the sharing link (which will disable access via the previous sharing link), or set Access to “Invitation Required” to ensure that nobody joins the class later without your permission. See the Members section in Shared Spaces above for more details and alternate methods for adding students to your space. Note that each student must have their own RStudio Cloud account.

RStudio Cloud | Creating an Assignment | Instructor View

A good way to create assignments for your students is to make a project for each assignment, and populate it with the files and packages you would like each student to have when they begin the assignment. When you are ready to reveal an assignment to your students, open the project and do the following: Click on the Project Settings button (the gear in the upper right) Select the Access panel Set the project access so it can be viewed by everyone in the space Check “Make this project an assignment” When the student opens an assignment project (either via the projects listing, or via a direct link to the project), RStudio Cloud will automatically make a copy for them. To convey this special behavior, assignments are displayed a bit differently, both for you and for your students. You can see the students’ copies of the assignment by clicking on the “View n derived projects” link that will appear with your original project. Note that changes you make to the original assignment will not be applied to any student copies already created. The changes will only apply to future copies of the assignment.

Oliver Bridges - Smart DCC | Energy Meetup | RStudio

Navigating the Analytics Journey at Smart DCC Presentation by Oliver Bridges Abstract: This talk will highlight the journey we have been (and still are) on that took us from outsourcing our analytics, to running some basic SQL and using graphical-based visualization tools, to open-source RStudio, and eventually to RStudio Team. Our evolution has been shaped by the huge volumes of data and demands from our customers that really led us to RStudio. While none of us are defined as data scientists, rather data engineers, our whole team has been on this journey with us and we’re continually learning as we go. From creating our own packages, APIs, pins, and Shiny dashboards we have now created workflows that allow us the deal with 10s of millions of records of aggregated data. As you start (or continue) on your own journey, I’d love to help share what we’ve learned along the way. Bio: Oliver Bridges is the Head of Data Science and Analytics at Smart DCC, designing and now managing a team of 15. Ollie has 15 years of experience in telecommunication and 10 years in smart metering. He has worked all around the world, including Cape Town, Copenhagen, Sydney, Amsterdam, Brussels, Dublin, and the UK. Ollie lives in Cornwall UK, and has worked remotely since the start of the pandemic, but before that worked in Manchester (about 300 miles from my house). In his spare time, he loves sport and coding! Smart DCC’s mission is to help digitise Britain’s energy network, and make a critical contribution in the effort to achieve net-zero greenhouse gas emissions, and improve the nation’s connectivity

Kaija Gahm | greenT (Shiny Contest) | RStudio

Kaija Gahm: greenT Shiny app greenT is a Shiny app I built to explore grapheme-color synesthesia, a neurological phenomenon where letters/numbers (graphemes) are associated with colors in my mind. Whenever friends found out about my synesthesia, they would want to know what color their names were in my head, and it got to be challenging to explain. When I found myself manually coloring squares in a spreadsheet to demonstrate what I saw in my mind’s eye, I decided to build an app instead. The app lets you either set your own colors or see what mine look like. Then you can enter text, and it will display as a series of rectangles according to the colors you’ve selected. I also added a feature that mimics a Google form to collect survey responses from other people with synesthesia, so they can submit their color data if they want to. Bio: My name is Kaija (rhymes with Maya), and I’m an incoming PhD student in the ecology/evolutionary biology department at UCLA, where I’ll be studying movement ecology and behavior of vultures using social network analysis. I’ve been using R for about six years, and for the past year I’ve been working as a data manager for an ecosystem science nonprofit. I’m on the board of SORTEE, an organization focused on openness and reproducibility in ecology and evolutionary biology. I didn’t come from a computer science background, so I’m passionate about talking to people about incorporating R into their work in accessible and friendly ways. When I’m not at my computer, you can usually find me outdoors (hiking or birdwatching) or spending entire days in the kitchen making up recipes. I tweet and blog, mostly about R

In the sales & operations planning (S&OP) process, we might need to run some scenarios to balance demand and supply to support sales: changing inventories plans, sales plans, delivery lead times, production plans, product mix, etc. Using Shiny, we can design simple, powerful, scalable, and reproducible apps for demand & supply planning as well as the S&OP process. In this talk, you will learn about real-life examples of web applications, which can be deployed in a few minutes to perform some popular demand & supply planning operations. __ Thank you to Nicolas for an awesome presentation on how he is using Shiny today. With all the interest from the community in this topic, we’d love to continue the discussion and connect us all through: Future meetups: https://www.meetup.com/RStudio-Enterprise-Community-Meetup/ R for Data Science Online Learning Community (“chat-supply_chain”): r4ds.io/join RStudio Community: community.rstudio.com

But early on in the vaccine distribution process, one state led the pack in terms of using the majority of vaccine doses it had been allotted. That state? West Virginia. Part of what has made West Virginia successful is the creation of an inventory management system using Shiny, an open source framework for building interactive web applications. The system was built by Data Driven West Virginia, part of the John Chambers College of Business and Economics at West Virginia University, in collaboration with the West Virginia Army National Guard. Using Shiny has provided visibility into each component of the vaccine supply chain, leading to the creation of distribution plans that are able to quickly and efficiently match supply with demand, getting vaccines to the right people in the right location at the right time. RStudio’s mission is to create free and open-source software for data science, scientific research, and technical communication to enhance the production and consumption of knowledge by everyone, regardless of economic means, and to facilitate collaboration and reproducible research, both of which are critical to the integrity and efficacy of work across industries. RStudio also produces RStudio Team, a modular platform of commercial software products that give organizations the confidence to adopt R, Python and other open-source data science software at scale, along with online services to make it easier to learn and use them over the web. Together, RStudio’s open-source software and commercial software form a virtuous cycle: the adoption of open-source data science software at scale in organizations creates demand for RStudio’s commercial software; and the revenue from commercial software, in turn, enables deeper investment in the open-source software that benefits everyone.

This starts with how vaccines are packed into containers. To fill up a container, Pfizer places 195 vials into a tray, and up to 5 trays into a single container. Moderna puts 10 vials into a small box, and then combines a minimum of 10 small boxes into a single container. In most states Pfizer and Moderna ship directly to the organization that will be administering the vaccine to the population. This could be a hospital, a pharmacy, or any place where trained professionals will be putting shots into arms. But what happens when a pharmacy receives a full container from Pfizer, 975 vials, but only needs 600? West Virginia has removed this complication by shipping directly to five hubs strategically located throughout the state. Within each of these hubs, containers of vaccine vials are broken down into smaller components and then either picked up or shipped directly to the hospital, pharmacy, or organization that will be administering the vaccine. These hubs are managed by the Joint Interagency Task Force (JIATF), a team of teams composed of public, private, and governmental organizations as well as the National Guard. The Joint Interagency Task Force is responsible for drawing up a weekly distribution plan for each hub, in alignment with CDC allocations, and matching vaccine supply with demand. By using a statewide system managed by a central organization, there’s a level of agility and fluidity that allows each hub to adjust to a variety of changes in order to maximize the number of vaccines that are being administered to the population each week. RStudio’s mission is to create free and open-source software for data science, scientific research, and technical communication to enhance the production and consumption of knowledge by everyone, regardless of economic means, and to facilitate collaboration and reproducible research, both of which are critical to the integrity and efficacy of work across industries.

Webinar Summary | Avoid Dashboard Fatigue | RStudio (2020)

0:00 Introduction 0:07 The Problem 1:05 The Solution 3:20 Real Life Success Stories 5:27 Demo (with code) Don’t have an hour to watch a webinar? We’ve made a summary video that covers the main points of our “Avoid Dashboard Fatigue” webinar from Sean Lopp and Rich Iannone. The full webinar covered: Data science teams face a challenging task. Not only do they have to gain insight from data, they also have to persuade others to make decisions based on those insights. To close this gap, teams rely on tools like dashboards, apps, and APIs. But unfortunately data organizations can suffer from their own success - how many of those dashboards are viewed once and forgotten? Is a dashboard of dashboards really the right solution? And what about that pesky, precisely formatted Excel spreadsheet finance still wants every week? In this webinar, we’ll show you an easy way teams can solve these problems using proactive email notifications through the blastula and gt packages, and how RStudio pro products can be used to scale out those solutions for enterprise applications. Dynamic emails are a powerful way to meet decision makers where they live - their inbox - while displaying exactly the results needed to influence decision-making. Best of all, these notifications are crafted with code, ensuring your work is still reproducible, durable, and credible. We’ll demonstrate how this approach provides solutions for data quality monitoring, detecting and alerting on anomalies, and can even automate routine (but precisely formatted) KPI reporting. Webinar materials: https://rstudio.com/resources/webinars/avoid-dashboard-fatigue/ About Sean: Sean has a degree in mathematics and statistics and worked as an analyst at the National Renewable Energy Lab before making the switch to customer success at RStudio. In his spare time he skis and mountain bikes and is a proud Colorado native. About Rich: My background is in programming, data analysis, and data visualization. Much of my current work involves a combination of data acquisition, statistical programming, tools development, and visualizing the results. I love creating software that helps people accomplish things. I regularly update several R package projects (all available on GitHub). One such package is called DiagrammeR and it’s great for creating network graphs and performing analyses on the graphs. One of the big draws for open-source development is the collaboration that comes with the process. I encourage anyone interested to ask questions, make recommendations, or even help out if so inclined!

Jenny Bryan | Help me help you: creating reproducible examples | RStudio (2018)

What is a reprex? It’s a reproducible example. Making a great reprex is both an art and a science and this webinar will cover both aspects. A reprex makes a conversation about code more efficient and pleasant for all. This comes up whenever you ask someone for help, report a bug in software, or propose a new feature. The reprex package ( https://reprex.Tidyverse.org ) makes it especially easy to prepare R code as a reprex, in order to share on sites such as https://community.rstudio.com, https://github.com, or https://stackoverflow.com. The habit of making little, rigorous, self-contained examples also has the great side effect of making you think more clearly about your programming problems. Webinar materials: https://rstudio.com/resources/webinars/help-me-help-you-creating-reproducible-examples/ About Jenny: Jenny is a software engineer on the tidyverse team. She is a recovering biostatistician who takes special delight in eliminating the small agonies of data analysis. Jenny is known for smoothing the interfaces between R and spreadsheets, web APIs, and Git/GitHub. She’s been working in R/S for over 20 years and is a member of the R Foundation. She also serves in the leadership of rOpenSci and Forwards and is an adjunct professor at the University of British Columbia

Hadley Wickham | testthat 3.0.0 | RStudio (2020)

In this webinar, I’ll introduce some of the major changes coming in testthat 3.0.0. The biggest new idea in testthat 3.0.0 is the idea of an edition. You must deliberately choose to use the 3rd edition, which allows us to make breaking changes without breaking old packages. testthat 3e deprecates a number of older functions that we no longer believe are a good idea, and tweaks the behaviour of expect_equal() and expect_identical() to give considerably more informative output (using the new waldo package). testthat 3e also introduces the idea of snapshot tests which record expected value in external files, rather than in code. This makes them particularly well suited to testing user output and complex objects. I’ll show off the main advantages of snapshot testing, and why it’s better than our previous approaches of verify_output() and expect_known_output(). Finally, I’ll go over a bunch of smaller quality-of-life improvements, including tweaks to test reporting and improvements to expect_error(), expect_warning() and expect_message(). Webinar materials: https://rstudio.com/resources/webinars/testthat-3/ About Hadley: Hadley Wickham is the Chief Scientist at RStudio, a member of the R Foundation, and Adjunct Professor at Stanford University and the University of Auckland. He builds tools (both computational and cognitive) to make data science easier, faster, and more fun. You may be familiar with his packages for data science (the tidyverse: including ggplot2, dplyr, tidyr, purrr, and readr) and principled software development (roxygen2, testthat, devtools, pkgdown). Much of the material for the course is drawn from two of his existing books, Advanced R and R Packages, but the course also includes a lot of new material that will eventually become a book called “Tidy tools”

Roche & Novartis: Effective Visualizations for Data Driven Decisions || Posit (2020)

Effective visual communication is a core task for all data scientists including statisticians, epidemiologists, machine learning experts, bioinformaticians, etc. By using the right graphical principles, we can better understand data, highlight core insights and influence decisions toward appropriate actions. Without it, we can fool ourselves and others and pave the way to wrong conclusions and actions. While numerous solutions exist to analyze data, these often require many manual steps to convert them into visually convincing and meaningful reports. How do we put this in practice in an accurate, transparent and reproducible way? In this webinar we will introduce an open collaborative effort, currently undertaken by Roche and Novartis, to develop solutions for effective visual communication with a focus on reporting medical and clinical data. The aim of the collaboration is to develop a user-friendly, fit for purpose, open source package to simplify the use of good graphical principles for effective visual communication of typical analyses of interventional and observational data encountered in clinical drug development. We will introduce the initial visR package design which easily integrates into a typical tidyverse workflow. The package provides guidance and meaningful default parameters covering all aspects from the design, implementation and review of statistical graphics.

Sean Lopp & Rich Iannone | Avoid Dashboard Fatigue | RStudio (2020)

Data science teams face a challenging task. Not only do they have to gain insight from data, they also have to persuade others to make decisions based on those insights. To close this gap, teams rely on tools like dashboards, apps, and APIs. But unfortunately data organizations can suffer from their own success - how many of those dashboards are viewed once and forgotten? Is a dashboard of dashboards really the right solution? And what about that pesky, precisely formatted Excel spreadsheet finance still wants every week? In this webinar, we’ll show you an easy way teams can solve these problems using proactive email notifications through the blastula and gt packages, and how RStudio pro products can be used to scale out those solutions for enterprise applications. Dynamic emails are a powerful way to meet decision makers where they live - their inbox - while displaying exactly the results needed to influence decision-making. Best of all, these notifications are crafted with code, ensuring your work is still reproducible, durable, and credible. We’ll demonstrate how this approach provides solutions for data quality monitoring, detecting and alerting on anomalies, and can even automate routine (but precisely formatted) KPI reporting. Webinar materials: https://rstudio.com/resources/webinars/avoid-dashboard-fatigue/ About Sean: Sean has a degree in mathematics and statistics and worked as an analyst at the National Renewable Energy Lab before making the switch to customer success at RStudio. In his spare time he skis and mountain bikes and is a proud Colorado native. About Rich: My background is in programming, data analysis, and data visualization. Much of my current work involves a combination of data acquisition, statistical programming, tools development, and visualizing the results. I love creating software that helps people accomplish things. I regularly update several R package projects (all available on GitHub). One such package is called DiagrammeR and it’s great for creating network graphs and performing analyses on the graphs. One of the big draws for open-source development is the collaboration that comes with the process. I encourage anyone interested to ask questions, make recommendations, or even help out if so inclined!

ZJ | Easy larger-than-RAM data manipulation with {disk.frame} | RStudio

Learn how to handle 100GBs of data with ease using {disk.frame} - the larger-than-RAM-data manipulation package. R loads data in its entirety into RAM. However, RAM is a precious resource and often do run out. That’s why most R user would have run into the “cannot allocate vector of size xxB.” error at some point. However, the need to handle larger-than-RAM data doesn’t go away just because RAM isn’t large enough. So many useRs turn to big data tools like Spark for the task. In this talk, I will make the case that {disk.frame} is sufficient and often preferable for manipulating larger-than-RAM data that fit on disk. I will show how you can apply familiar {dplyr}-verbs to manipulate larger-than-RAM data with {disk.frame}. About ZJ: ZJ is a machine learning developer based in Melbourne, Australia. He regularly contributes to open source projects. He has more than 10 years of experience in banking before joining the tech sector. In his free time, he enjoys playing Go/Baduk/Weiqi

Chelsea Parlett-Pelleriti | Hands-on ways to remotely teach data science are invaluable | RStudio

Full title: With more learning occurring virtually or in hybrid mode, hands-on ways to remotely teach data science are invaluable With more learning occurring virtually or in hybrid mode, hands-on ways to remotely teach DS are invaluable. Guided simulation exercises in R allow learners to explore concepts deeply, on their own time, and with others. They can also experiment with the simulations, try out edge cases, and challenge their assumptions, leading to more fruitful discussions. The comparison between coefficient estimates in regular, LASSO, and RIDGE regression, or how PCA performs when data are related are great examples of concepts where guided simulations can encourage learners to build intuitive knowledge. This talk explores how to use simulation exercises in R to help learners explore DS concepts and provides examples. About Chelsea: Chelsea Parlett-Pelleriti is a PhD Candidate and full-time instructional faculty teaching Data Science at Chapman University. Her research centers around how we can use statistics and machine learning to improve the way we analyze behavioral data.

Carson Sievert | Custom theming in Shiny & R Markdown with bslib & thematic | RStudio

Custom theming in Shiny and R Markdown often requires writing styling rules in both CSS and R. In particular, styles for HTML content (e.g., actionButton(), tabsetPanel(), titlePanel(), etc) derive from Bootstrap CSS, so customization is traditionally done by overwriting that CSS, which is difficult to do 100% correctly. The {bslib} package helps solve this problem by making it easy to customize (any version of) Bootstrap CSS defaults from R. However, this only solves part of the problem since CSS doesn’t necessarily effect output(s) rendered by R, such as plotOutput(). The {thematic} package helps solve this problem by providing auto theming of plotOutput()s (based on CSS) as well as a simple interface for styling any R graphic for any output format. About Carson: Carson is a software engineer at RStudio working on R packages such as shiny, shinymeta, and plotly. His book “Interactive data visualization with R, plotly, and shiny”, published by CRC Press, is also freely available online at plotly-r.com

Athanasia M. Mowinckel | Make a package - Make some friends | RStudio

In 2017, I had never exposed my code to anyone other than a select few before, and I was terrified. I had some functions made from a colleagues script that I thought might be useful for others, and dared myself to make a package and push it to github. In stead of the dreaded ridiculing of poor code and development, people embraced the package and helped us make it better. Within just a couple of days, pull requests came from others to help us improve the code, implement tests, and improve documentation. I learned so much just by looking through the PRs and seeing how others worked. Rather than make me shy off development, the R neuro community’s positive feedback has helped me find a new interest and joy in developing tools. About Athanasia: Athanasia M. Mowinckel is a staff scientist at the Center for Lifespan Changes in Brain and Cognition, at the University of Oslo. She has a background on cognitive psychology, and uses R for almost everything. She goes by the nickname “Mo” (closer to ‘Mou’ than ‘Moe’), and is a member of the R-Ladies Global team

Alex Cookson | The Power of Great Datasets | RStudio

There are a few classic datasets, like mtcars, nycflights, or Titanic passengers. They’re okay, but they leave something to be desired for folks learning R: they’re kind of boring. There’s a big difference between “Okay Datasets” and “Great Datasets”. Great Datasets prompt you to exclaim, “That’s so cool!” They get your blood pumping and mind racing with questions you want answered. They give tremendous motivation to answer those questions. And in answering those questions, you’ll probably learn some R. I want you to curate Great Datasets. You’ll contribute to the richness of our community, you’ll learn some R yourself, and you’ll feel fantastic when someone finds your Great Dataset and exclaims, “That’s so cool!” About Alex: Alex Cookson helps the Customer Intelligence team at the Royal Canadian Mint make the most of their data. When he’s not working on A/B testing, recommendation engines, or exploratory data analysis at the Mint, he can be found participating in Tidy Tuesday or thinking up cool datasets to explore. And when he’s not doing that, he’s probably cycling around Toronto or doting on his two cats, Tom Tom and Ruby

Alan Feder | Categorical Embeddings: New Ways to Simplify Complex Data | RStudio

When building a predictive model in R, many of the functions (such as lm(), glm(), randomForest, xgboost, or neural networks in keras) require that all input variables are numeric. If your data has categorical variables, you may have to choose between ignoring some of your data and too many new columns. Categorical embeddings are a relative new method, utilizing methods popularized in Natural Language Processing that help models solve this problem and can help you understand more about the categories themselves. While there are a number of online tutorials on how to use Keras (usually in Python) to create these embeddings, this talk will use embed::step_embed(), an extension of the recipes package, to create the embeddings. About Alan: Alan Feder is a Principal Data Scientist at Invesco, where he uses as much R as possible to solve problems and build products throughout the company. Previously, he worked as a data scientist at AIG and an actuary at Swiss Re. He studied statistics and mathematics at Columbia University. He is unreasonably excited to spread the word about categorical embeddings. Alan lives in New York City with his wife, Ashira, and two children, Matan and Sarit

Shelmith Kariuki | rKenyaCensus Package | RStudio

The rKenyaCensus package contains the results of the 2019 Kenya Population Census. The census exercise was carried out in August 2019, and the results were released in February 2020. Kenya leveraged on technology to capture data during cartographic mapping, enumeration and data transmission, making the 2019 Census the first paperless census to be conducted in Kenya. The data was published in four different pdf files (Volume 1 - Volume 4) which can be found in the Kenya National Bureau of statistics website. The data in its current form was open and accessible, but not usable and so there was need to convert it into a machine readable format. This data can be used by the government, non-governmental organizations and any other entities for data driven policy making and development. During the talk, I will explain the reasons behind development of the package, take you through the steps I took during the process and finally showcase analysis of certain aspects of the data. About Shelmith: Shelmith Kariuki is a Senior Data Analyst based in Nairobi, Kenya. She is an RStudio Certified Tidyverse trainer ( https://education.rstudio.com/trainers/), currently working as a Data Analytics consultant with UN DESA.

Sean Lopp | R & Python: Going Steady | RStudio

While there has been a lot of excitement about the R and Python love story, there are still misconceptions that individuals, teams, or organizations must pick between R or Python. This talk will explain why this false choice exists, debunk the myths that cause teams to be stuck with only one tool, and clarify how data scientists can use both languages to be more effective. We will explore this love story’s blossoming relationship by looking at updates to RStudio’s packages and products that make it easier to develop and collaborate in R and Python. This talk is for individuals who want to uncover the benefits of multilingual data science, IT professionals who are skeptical their life can get better by supporting more languages, and data science managers interested in enabling their teams instead of forcing their data superheros to be subservient to particular tools. About Sean: Sean has a degree in mathematics and statistics and worked as an analyst at the National Renewable Energy Lab before making the switch to customer success at RStudio.

Riva Quiroga | Learning to program in R with a “communicative approach” | RStudio

Full title: How to do things with words: learning to program in R with a “communicative approach” Textbooks for learning a new language always start the same: you learn to say hello, to introduce yourself, and some simple and useful sentences to communicate with others. In language teaching, this is called a “communicative approach”, and is based on the idea that learning a language successfully comes through having to communicate real meaning to real people. This is what I expected to find when I first tried to learn R seven years ago. Sadly, I got stuck in resources that started with definitions of abstract concepts and no real examples of how to say things with data. In this talk I will discuss the benefits of adopting a communicative approach and how to implement it when teaching/learning R, writing documentation, and writing code that will be read by other human beings. About Riva: I like to organize R related things, like meetups (RLadies Santiago & RLadies Valparaíso), conferences (LatinR, satRday Santiago), book translations (R4DS in Spanish), and data projects (#DatosDeMiercoles). I am an editor at The Programming Historian, and I am currently pursuing a PhD in Linguistics

Nicole Kramer | A New Paradigm for Multifigure Coordinate-Based Plotting in R | RStudio

R is unparalleled in its ability to transform raw data into a wide array of beautiful graphics, all within the same environment. However, when it comes to complex, multi-paneled plots, users rely on 3rd party graphic design software to arrange plots. Here I present the new world of programmatic, coordinate-based multi-figure plotting in R. Employing grid Graphics and drawing from the paradigms of base plotting and ggplot2, I am developing a package that will revolutionize the way plots are laid out in R. Not only will individual plots be aesthetically customizable and tailored for speed, users will also be offered exquisite control over all aspects of page layout, plot placement, and arrangements. Come join me in changing how we plot in R! About Nicole: Nicole Kramer is a third year Bioinformatics and Computational Biology graduate student at the University of North Carolina at Chapel Hill. She works in the lab of Dr. Doug Phanstiel, where her and her colleagues use experimental and computational techniques to study human genomics.

Mine Çetinkaya-Rundel | Feedback at scale | RStudio

As enrollments in statistics and data science courses grow and as these courses become more computational, educators are faced with an interesting challenge – providing timely and meaningful feedback, particularly with online delivery of courses. The simplest solution is using assignments that are easier to auto-grade, e.g. multiple-choice questions, simplistic coding exercises, but it is impossible to assess mastery of the entire data science cycle using only these types of exercises. In this talk I will discuss writing effective learnr exercises, providing useful and motivating feedback with gradethis, distributing them at scale online and as an R package, and collecting student data for formative assessment with learnrhash. About Mine: Mine Çetinkaya-Rundel is Professional Educator and Data Scientist at RStudio as well as Senior Lecturer in the School of Mathematics at University of Edinburgh (on leave from Department of Statistical Science at Duke University). Mine’s work focuses on innovation in statistics and data science pedagogy, with an emphasis on computing, reproducible research, student-centered learning, and open-source education as well as pedagogical approaches for enhancing retention of women and under-represented minorities in STEM. Mine works on integrating computation into the undergraduate statistics curriculum, using reproducible research methodologies and analysis of real and complex datasets. She also organizes ASA DataFest and works on the OpenIntro project. She is also the creator and maintainer of datasciencebox.org and she teaches the popular Statistics with R MOOC on Coursera

Michael Chow | Bringing the Tidyverse to Python with Siuba | RStudio

Last January I left my job to spend a year developing siuba, a python port of dplyr. At its core, this decision was driven by a decade of watching python and R users produce similar analyses, but in very different ways. In this talk, I’ll discuss 3 ways siuba enables R users to transfer their hard-earned programming knowledge to python: (1) leveraging the power of dplyr syntax, (2) options to generate SQL code, and (3) working with the plotnine plotting library. Looking back, I’ll consider two critical pieces that have helped me develop siuba: using it to livecode TidyTuesday analyses, and building an interactive tutorial for absolute beginners. About Michael: Michael Chow is a data scientist and learning researcher. He serves as a co-director at Code for Philly. In past lives, he worked on adaptive assessment tools in ed tech, and received a PhD in cognitive psychology from Princeton University

Megan Beckett | Aesthetically automated figure production | RStudio

Automation, reproducibility, data driven. These are not normally concepts one would associate with the traditional publishing industry, where designers normally manually produce every artefact in proprietary software. And, when you have 1000s of figures to produce and update for a single textbook, this becomes an insurmountable task, meaning our textbooks quickly become outdated, especially in our rapidly advancing world. With R and the tidyverse in our back pocket, we rose to the challenge to revolutionize this workflow. I will explain how we collaborated with a publishing group to develop a system to aesthetically automate the production of figures for a textbook including translations into several languages. I think you’ll find this talk interesting as it shows how we applied tools that are familiar to us, but in an unconventional way to fundamentally transform a conventional process. About Megan: Megan Beckett is a Data Scientist at Exegetic Analytics, where she consults, develops and leads several analytical projects across a wide range of fields and industries. “Scientifically creative; creatively scientific.” This aptly describes her philosophy and approach in her work and life. Megan helped co-found and organises the Cape Town R-Ladies chapter and is a co-organiser of the satRday events in South Africa. She loves to paint, with her most recent work exploring the biodiversity of southern Africa, and running is her passion, whether on the road or the trail

Maya Gans | Starting an R Book Club: Cooking Up Friendships in Isolation | RStudio

Amidst a global pandemic there’s been one consistency in my life: every Tuesday a group of friends meet to discuss Hadley Wickham’s Advanced R. I crowdsourced interest using the R4DS Slack and the results were magical: a group of incredibly curious and generous people motivated to learn and teach one another emerged. The meetings evolved from a group of strangers giving timid presentations to a safe space where we share and improve upon personal applications. The 1 club has grown to 3 regional cohorts, and became a model for discussing other books too. This talk will go over the structure of our meetings in hopes of empowering others to start their own book clubs, showcasing a different way people can create and engage in communities. About Maya: I am a mycologist turned data scientist. I love statistics, data visualization, and all things JavaScript.

Matt Thomas & Mike Page | How the Tidyverse helped the British Red Cross respond to COVID | RStudio

Full title: Cognitive speed: How the Tidyverse helped the British Red Cross respond quickly to COVID-19 We will discuss the importance of cognitive speed, defined here as the rate in which an idea can be translated into code, and why the Tidyverse excels in this domain. We will demonstrate this idea in relation to a suite of tools we were required to rapidly develop at the British Red Cross in order to respond effectively to the COVID-19 pandemic. To do this, we will exhibit how elements of the unifying design principles outlined in the ‘tidyverse design guide - Tidyverse team’ relate to the notion of cognitive speed, giving specific examples for various design considerations. We believe this talk will encourage reflection on better design practices for future R developers, using the design principles of the tidyverse as the guiding beacon. About Matt: Dr. Matt Thomas is Head of Strategic Insight and Foresight at the British Red Cross. Matt’s team aims to help the Red Cross become more anticipatory and proactive by producing insights and tools including the Vulnerability Index ( https://britishredcrosssociety.github.io/covid-19-vulnerability/ ) and Resilience Index ( https://britishredcross.shinyapps.io/resilience-index/). He holds a PhD in Evolutionary Anthropology and, prior to joining the British Red Cross, was researching topics including reindeer herders in the Arctic, hunter-gatherers in the Philippines, and witches in China.

Marcus Adams | Putting a GMP Shiny App into Production | RStudio

Full title: Not The App We Deserve. The App We Need: Putting a GMP Shiny App into Production In February 2020, the Digital Proactive Process Analytics (DPPA) group within Merck’s manufacturing division officially launched a Shiny app to automate the creation of Continuous Process Verification (CPV) reports into production. That’s right – the almighty, mysterious, coveted production. From a technical perspective, the app is nothing particularly special (except other than getting LaTeX successfully installed to support the use of R Markdown). Users enter a few parameters and out pops a PDF with a series statistical analyses of a product’s quality testing data. The R blogosphere is filled with examples of similar Shiny apps. What mattered was the app was in production, and furthermore it was approved for GMP use. This meant these reports could be submitted to the FDA and other regulatory agencies. This meant the data could be used to support product release decisions. This meant Merck’s engineers were about to save thousands of hours per year in compiling data, generating charts, and calculating summary statistics. This was the app manufacturing sites needed. Most of the work in getting this app into production was not implementing the top-level features. Sorry, no discussion of fancy statistical process control methods here. Instead this talk will discuss some of the many things the development team (none of which came from a software development background) needed to learn in order to create a robust, secure, and maintainable production application. About Marcus: Marcus Adams is an Associate Director, Engineering at the biopharmaceutical company Merck. He earned his BEng and MS in Chemical Engineering from the University of Delaware and Villanova University, respectively. His more than decade of experience at Merck spans the bio-pharmaceutical spectrum and includes experience in pre-clinical PK/PD modeling, product commercialization, in-line technology support, procurement, and vaccine distribution technology development. Currently, he works as a part of the Digital Proactive Process Analytics team, leveraging Merck’s Big Data Platform in the development of manufacturing information data models, report automation tools, and integrated-systems analysis applications. His professional interests include effective digital visualization, reproducible research/analysis, and convincing his coworkers of the diverse, flourishing world beyond Microsoft Excel

Malcolm Barrett | You’re Already Ready: Zen and the Art of R Package Development | RStudio

R packages make it easier to write robust, reproducible code, and modern tools in R development like usethis make it easy to work with packages. When you write R packages, you also unlock a whole ecosystem of tools that will make it easier to test, document, and share your code. Despite these benefits, many believe package development is too advanced for them or that they have nothing to offer. A fundamental belief in Zen is that you are already complete, that you already have everything you need. I’ll talk about why your project is already an R package, why you’re already an R package developer, and why you already have the skills to walk the path of development. About Malcolm: Malcolm Barrett is Clinical Research Data Scientist at Teladoc Health, an epidemiologist, and an R developer. He is also an organizer for the Los Angeles R Users Group. Malcolm is the author of several R packages, including ggdag and precisely. Previousy, he was an intern at RStudio and spent two years of service in AmeriCorps.

Kate Hertweck | R training and documentation for different levels of expertise | RStudio

Full title: Making the jump from learning to applying: R training and documentation for different levels of expertise How does someone make the leap from learning R to actively applying R in professional work? At what point (if ever!) do we get to call ourselves “experts in R? This talk explores what differentiates novice, practitioner, and expert R programmers, and how transitions between these stages occur. I’ll discuss the type of support required for R users to move from one level of expertise to the next, and how different types of training and documentation can support R users at each level. Understanding variable levels of education among R practitioners supports our own professional work, from collaborative coding to package development, and helps build a bigger, more inclusive R community. About Kate: Kate Hertweck is the bioinformatics training manager at Fred Hutchinson Cancer Research Center, where they develop and teach courses on reproducible computational methods as a part of fredhutch.io. Kate’s graduate training at University of Missouri in genomic evolution of plants was followed by a postdoctoral fellowship at the National Evolutionary Synthesis Center (NESCent) at Duke University, where they fell in love with R and began working exclusively in computational biology. Kate then spent four years as an assistant professor teaching bioinformatics, genomics, and plant taxonomy before transitioning to biomedical research training. Kate has been involved in The Carpentries, a non-profit organization that teaches reproducible computational methods, since 2014, serving as a leader in community governance since 2016.

Kara Woo | Always look on the bright side of plots | RStudio

Everyone who creates visualizations in R is bound to make mistakes that prevent their plots from looking as they should. Sometimes, these mistakes create beautiful “accidental aRt”, though other times they’re just plain frustrating. Either way, however, there’s something to be learned. This talk will draw on years of watching both the ggplot2 issue tracker and the @accidental__aRt twitter account to highlight some common plot foibles and explain what they can teach us about how ggplot2 works. About Kara: Kara Woo is a research scientist in data curation at Sage Bionetworks, where she builds tools to help researchers document and share their data. Kara is a core developer of ggplot2 and collects data visualizations gone beautifully wrong on a blog called accidental aRt

Jeroen Ooms | Monitoring health and impact of open-source projects | RStudio

At rOpenSci, we have come to realize that in order to help researchers get the most out of R, we need better tooling to monitor the quality, health, and impact of R packages. This applies both to our internal projects, as well as other packages in the R ecosystem. But what exactly makes a good R package? In this talk we discuss various aspects of open-source software that are not always immediately obvious, and that you may want to consider when depending on an R package. We identify several categories of indicators you could look for, ranging from the role in the dependency network, to expectations around maintenance and participation. Finally we introduce an ambitious new rOpenSci project called R-universe: an open platform, where we will experiment with showing metrics and other background information about packages, that may reveal something about the health and the impact of the project, and also facilitate discovery of other software.

Javier Luraschi | Using pins with Python and JavaScript | RStudio

Last year, pins got released as a brand new R package to pin, discover and cache remote resources for R users. This package has matured to support many use cases; from caching remote URLs, and easily sharing datasets with other R users, to building automated pipelines. However, in order to truly collaborate in multi-disciplinary data-driven teams, one needs to consider how to collaborate beyond R. How can we share resources with designers and machine learning experts who happen to use different programming languages like Python and JavaScript? This talk will introduce the pinsjs project, a cross-language community project which has the goal of bringing pins to the broader open source community to enable rich workflows across larger data-driven teams. About Javier: Javier is the author of “Mastering Spark with R”, pins, sparklyr, mlflow and torch. He holds a double degree in Math and Software Engineer and decades of industry experience with a focus on data analysis.

Irene Steves | The dynamic duo: SQL & R | RStudio

There’s a point in every data wranglers’ career in which their full dataset can no longer fit into just CSV files, and the journey to database-world begins. I reached this point about two years ago, when I transitioned from ecological research to the world of eCommerce fraud prevention. My calls to read_csv became scarcer as I came to rely more and more on databases. In this talk, I’ll demonstrate how I use R and SQL to access database tables, and how I incorporate both into my daily workflow, aided by features in RStudio IDE. I’ll also discuss our company’s “riskiconn” package for handling database connections and queries, which includes customizations to simplify day-to-day data querying. About Irene: Irene holds an M.Sc. in Ecology and a B.A. in Integrative Biology, through which she first discovered R and data science. Her interest in data led her to the Arctic Data Center at the University of California Santa Barbara, a summer internship at RStudio, and ultimately to the Research & Data Science department at Riskified, where she now explores the complex patterns of fraud in eCommerce. In her free time, she studies Hebrew through podcasts and dubbed kids’ movies

Grant Fleming | Fairness and Data Science: Failures, Factors, and Futures | RStudio

In recent years, numerous highly publicized failures in data science have made evident that biases or issues of fairness in training data can sneak into, and be magnified by, our models, leading to harmful, incorrect predictions being made once the models are deployed into the real world. But what actually constitutes an unfiar or biased model, and how can we diagnose and address these issues within our own work? In this talk, I will present a framework for better understanding how issues of fairness overlap with data science as well as how we can improve our modeling pipelines to make them more interpretable, reproducible, and fair to the groups that they are intended to serve. We will explore this new framework together through an analysis of ProPublica’s COMPAS recidivism dataset using the tidymodels, drake, and iml packages. About Grant: Grant Fleming is a Data Scientist at Elder Research, co-author of the Wiley book Responsible Data Science (2021), and contributor to the O’Reilly book 97 Things About Ethics Everyone in Data Science Should Know. His professional focus is on machine learning for social science applications, model explainability, and building tools for reproducible data science.

Eric Cronstrom | How we made the switch: a case study on automating a complex report | RStudio

The Center for Charter Schools at Central Michigan University produces annual reports for about 60 schools. The reporting process used to be a cumbersome blend of many technologies. The Center used to use a blend of SQL, Excel, inDesign, and VBScript that would all culminate in a nice looking, branded report for each school. 2 years ago, staff turnover allowed the data team to rethink the process, having had experience in R from graduate work the team at the Center decided to go all in on R Studio and R Markdown for report production a mere 1 month before the reports were due to be published. This talk will be a case study of how we as an organization adopted RStudio tools to streamline a cumbersome process to fantastic results. About Eric: Eric is responsible for administering a wide range of day to day program functions associated with the performance and accountability of CMU partner schools. He ensures that the data the Center utilizes to evaluate school performance is accurate and stored within a sound data infrastructure.

Ahmadou Dicko | Humanitarian Data Science with R | RStudio

Humanitarian actors are increasingly using data to drive their decisions. Since the Haiti 2010 earthquake, the volume of data collected and used by humanitarians has been growing exponentially and organizations are now relying on data specialists to turn all this data into life-saving data products. These data products are created by teams using proprietary point and click software. The process from the raw data to the final data product involves a lot of clicking, copying and pasting and is usually not reproducible. Another approach to humanitarian data science is possible using R. In this talk, I will show how to seamlessly develop reproducible, reusable humanitarian data products using the tidyverse, rmarkdown and some domain-focused R packages. About Ahmadou: Ahmadou Dicko is a statistics and data analysis officer at the United Nations High Commissioner for Refugees (UNHCR) where he uses statistics and data science to help safeguard the rights and well-being of refugees in West and Central Africa. He has an extensive experience in the use of statistics and data science in development and humanitarian projects. Ahmadou was the lead of the OCHA Center for Humanitarian Data team for West and Central Africa and has worked with several humanitarian and development organizations such as IFRC, FAO, IAEA, OCHA. Ahmadou is a RStudio trainer ( https://education.rstudio.com/trainers/ ) and he is passionate about the R community.

Aaron Jacobs | Introducing xrprof: A New Way to Profile R | RStudio (2021)

Tracking down performance issues in R code usually means using R’s built-in Rprof() profiler or one of the packages built around it. But the changing nature of the R community (towards more deployed applications) makes local profiling workflows frustrating, which is why I have written a new profiler: xrprof. xprof is compatible with existing R tools, but unlike them it can be used to profile R code that is already running – in fact, it is designed to be safe to point at R code running ““in production””. xrprof also works seamlessly when R is run inside Docker, and can even be run in complex environments like Kubernetes clusters. Taking inspiration from the {jointprof} package, xrprof can also show function calls at the C/C++ level alongside those from R. This can be immensely useful for diagnosing problems in packages that make heavy use of compiled code. About Aaron: Aaron Jacobs is a Senior Data Scientist on the R&D team at Crescendo, a technology company in the sports betting space with a large internal R ecosystem. Prior to Crescendo he worked in Canadian public policy research. Aaron has a strong interest in the engineering side of data science and the emerging use of R “in production”. He is the author of several CRAN and GitHub packages, as well as xrprof – a new R profiling tool

Mary Rudis | How R and Posit are revolutionizing Stats Education in Community Colleges | Posit

Talk from rstudio::conf(2019) There is no doubt that Posit has had an impact on how introductory statistics is taught in colleges today. When we consider the sheer dominance that giants like Texas Instruments, IBM, and Pearson Publishing have had in academic curriculum development, it’s no small wonder that tools like R and Python have been able to gain a foothold. Projects like DataCamp, ModernDive.com, “Introductory Statistics with Randomization and Simulation” courtesy of openintro.org, Wickham’s “R for Data Science” and Peng’s “R Programming for Data Science” are great resources for the student who has already some fundamental math or statistical background and has become comfortable around computing and applications-driven computational exercises. But many of us know that Data Science cannot simply be relegated to the privileged few that stumble into it by virtue of circumstance. My passion, and the purpose of my talk, is to provide educators with a digestible guidebook that would be appropriate for introduction to statistical concepts in high school, college, and under-resourced schools looking for ways to increase diversity in STEM. Organized in small, adaptable activities designed to be the amuse-esprit enticing both the timid and the skeptical to the proverbial banquet table that is Posit, this exploration into the world of statistics education should be of interest to a wide audience. My hope is to increase data literacy in real world context – with primary emphasis on descriptive statistics and distributions. About Mary Rudis: After graduating from Lehigh University in Bethlehem, PA with a degree in Mathematics, Mary began as a high school mathematics and computer science teacher, developing technology infrastructure for a small, private high school in Pennsylvania. Throughout her career, she brings innovative approaches and enjoys the role of trailblazer. Mary’s most recent accomplishments as math department chair included developing mathematics curriculum and coordinating engineering, bioengineering and data science degrees at Great Bay Community College in Portsmouth, NH. Mary’s primary interests are learning and instruction, developing data science curricula for two-year colleges and 4-year liberal arts colleges, and working with area high school students in STEM at the University of NH Tech Camp each summer

Kelly Nicole Bodwin | Intro stats with R: Easing the transition to software for beginners | RStudio

Talk from rstudio::conf(2019) In this talk, we will present our approach to incorporating R and RStudio into a 10-week introductory statistics course for non-majors Cal Poly. Our primary contribution will be to share a series of Shiny Apps, created to ease students with no statistical or coding background into the philosophy of using programming tools to explore data. Our program was recently used in 3 sections of 35 students each this Fall, during which students were surveyed regularly for their reactions to the approach. We will demonstrate our new tools, discuss our successes and failures, share student-generated output, and summarize the results of our Fall survey. Kelly teaches at Cal Poly in San Luis Obispo, California, where she takes great joy in forcing statistical thought and R skills upon unsuspecting undergraduates. Her research is in clustering methods, digital humanities, and R tools for education. In her free time, she hikes and camps, plays board games, and tweets too much about R

JD Long | Empathy in action: Building community of practice for analytics in a global corp | RStudio

Talk from rstudio::conf(2019) JD Long, Vice President of Risk Management & Data Philosophy at the global reinsurer Renaissance Re will share his experience with creating a “Community of Practice” for analytics inside of a global corporation. The theme of “empathy” will be recurring as he discusses how he worked to create a supportive learning environment focused on helping analysts “kick ass” regardless of their tool set. This means creating a community that’s supportive of Excel, SQL, Python, and, of course, R. About JD Long: I build models. And according to George E. P. Box, my models are wrong. My skill is understanding when and where my models are useful. I’m an experienced risk and data scientist with a background in insurance, reinsurance, market risk, and stochastic modeling. I’m the guy who can build a Monte Carlo model, help parallelize the model to run on Amazon’s cloud services and then stand in front of a general audience and put the work in context where everyone understands. My super power is thinking probabilistically, understanding risk, and communicating clearly. I have a history forming bridges between IT and business teams

Heather & Jacqueline Nolis | Push straight to prod: API development with R and Tensorflow | RStudio

Talk from rstudio::conf(2019) When tasked with creating the first customer-facing machine learning model at T-Mobile, we were faced with a conundrum. We had been told time and time again to deploy machine learning models in production you had to use Python, but our very best data scientists were fluent in building neural networks in R with Keras and TensorFlow. Determined to avoid double work, we decided to use R in production for our machine learning models. After months of work, wrangling our containers to meet cloud security compliance, and conforming to DevOps standards, we succeeded in creating a containerized API solution using the keras and plumber R packages and Docker. Today R is actively powering tools that our customers directly interact with and we have open sourced our methods. In this talk, we’ll walk through how to deploy R models as container-based APIs, the struggles and triumphs we’ve had using R in production, and how you can design your teams to optimize for this sort of innovation. About Heather Nolis: Heather Nolis is a founding member of the AI @ T-Mobile team, focusing the conversion of cutting-edge analyses to real-time, scalable data-driven products. She began her career in neuroscience but once realized how heavily that field relied on software built by other people, she pivoted - deciding to make software herself. You can find her @heatherklus on Twitter, where she speaks about diversity in technology, the ethical implications of data, and cats. About Jacqueline Nolis: Dr. Jacqueline Nolis is a co-founder of Nolis, LLC, a data science consulting firm. She has over a decade of experience using data to help companies including DSW, Union Bank, Microsoft, and Airbnb. She has a PhD from Arizona State University where her research focused on electric vehicle route optimization. For fun she likes to use machine learning for humor

Jake Thompson | Branding and Packaging Reports with R Markdown | RStudio (2020)

The creation of research reports and manuscripts is a critical aspect of the work conducted by organizations and individual researchers. Most often, this process involves copying and pasting output from many different analyses into a separate document. Especially in organizations that produce annual reports for repeated analyses, this process can also involve applying incremental updates to annual reports. It is important to ensure that all relevant tables, figures, and numbers within the text are updated appropriately. Done manually, these processes are often error prone and inefficient. R Markdown is ideally suited to support these tasks. With R Markdown, users are able to conduct analyses directly in the document or read in output from a separate analyses pipeline. Tables, figures, and in-line results can then be dynamically populated and automatically numbered to ensure that everything is correctly updated when new data is provided. Additionally, the appearance of documents rendered with R Markdown can be customized to meet specific branding and formatting requirements of organizations and journals. In this presentation, we will present one implementation of customized R Markdown reports used for Accessible Teaching, Learning, and Assessment Systems (ATLAS) at the University of Kansas. A publicly available R package, ratlas, provides both Microsoft Word and LaTeX templates for different types of projects at ATLAS with their own unique formatting requirements. We will discuss how to create brand-specific templates, as well as how to incorporate the templates into an R package that can be used to unify report creation across an organization. We will also describe other components of branding reports beyond R Markdown templates, including customized ggplot2 themes, which can also be wrapped into the R package. Finally, we will share lessons learned from incorporating the R package workflow into an existing reporting pipeline. https://rstudio.com/resources/rstudioconf-2020/branding-and-packaging-reports-with-r-markdown/

Many models have structural parameters that cannot be directly estimated from the data. These tuning parameters can have a significant effect on model performance and require some mechanism for finding reasonable values. The tune and workflow packages enable tidymodels users to optimize these parameters using a variety of efficient grid search methods as well as with iterative search techniques (such as Bayesian optimization)

Joe Cheng | Styling Shiny apps with Sass and Bootstrap 4 | Posit (2020)

Customizing the style–fonts, colors, margins, spacing–of Shiny apps has always been possible, but never as easy as we’d like it to be. Canned themes like those in the shinythemes package can easily make apps look slightly less generic, but that’s small consolation if your goal is to match the visual style of your university, corporation, or client. In theory, one can “just” use CSS to customize the appearance of your Shiny app, the same as any other web application. But in practice, the use of large CSS frameworks like Bootstrap means significant CSS expertise is required to comprehensively change the look of an app. Relief is on the way. As part of a round of upgrades to Shiny’s UI, we’ve made fundamental changes to the way R users can interact with CSS, using new R packages we’ve created around Sass and Bootstrap 4. In this talk, we’ll show some of the features of these packages and tell you how you can take advantage of them in your apps. Resources: https://speakerdeck.com/jcheng5/styling-shiny

Alicia Schep | Auto-magic Package Development | RStudio (2020)

Vega-lite is a high-level grammar of interactive graphics implemented in Javascript; it renders interactive visualizations in the browser based on a JSON specification. In Python and Javascript, the Altair and vega-lite-api packages have demonstrated how the development of APIs to build Vega-Lite graphics can be partially automated based on the Vega-Lite JSON schema, which describes the required format for a Vega-Lite JSON specification. This talk will describe the development of the ‘vlbuildr’ package for building Vega-Lite specifications in R and the ‘vlmetabuildr’ package for building the ‘vlbuildr’ package. The ‘vlbuildr’ package seeks to provide a pipe-friendly, “R-like” functional interface for building up simple to complex specifications for Vega-Lite graphics, which can in turn be rendered as an HtmlWidget by the ‘vegawidget’ R package. Building such an API in a fully automated way from the Vega-Lite schema presents considerable challenges, so the approach taken here was to rely on partial automation. Human judgement dictates the basic contours of the API, such as what groups of functions to include and how various types of building blocks will go together. The part that is automated is filling in many details such as the different variants of a group of functions, the exact parameters needed for each function, and the documentation of those parameters – the parts that would be extremely tedious to port over!

Gordon Shotwell | Technical Debt is a Social Problem | Posit (2020)

Technical debt is a big problem for the R community. Even though R has excellent support for testing, documentation and packaging code it has the reputation that it is not suitable for production applications because data scientists don’t pay enough attention to technical debt within their codebases. Most people think of technical debt as an engineering problem. We choose to make our current work cheaper at the expense of needing to do more work down the road. But when you look closely at the root causes of technical debt they are almost always about interpersonal relationships. Developers have trouble empathizing with other users of their code and so don’t spend the time to make that code easy for future developers to use and understand. In this talk I argue that we should think about technical debt as a social problem because it gives us insight into why it’s so hard to pay back. I then provide a practical roadmap of how to introduce best practices into your data science team

Ellis Hughes | Approaches to Assay Processing Package Validation | RStudio (2020)

In this talk I will discuss the steps that have been created for validating internally generated R packages at SCHARP (Statistical Center for HIV/AIDS Research and Prevention) and the lessons learned while creating packages as a team. Housed within Fred Hutch, SCHARP is an instrumental partner in the research and clinical trials surrounding HIV prevention and vaccine development. Part of SCHARP’s work involves analyzing experimental biomarkers and endpoints which change as the experimental question, analysis methods, antigens measured, and assays evolve. Maintaining a validated code base that is rigid in its output format, but flexible enough to cater a variety of inputs with minimal custom coding has proven to be important for reproducibility and scalability. SCHARP has developed several key steps in the creation, validation, and documentation of R packages that take advantage of R’s packaging functionality. First, the programming team works with leadership to define specifications and lay out a roadmap of the package at the functional level. Next, statistical programmers work together to develop the package, taking advantage of the rich R ecosystem of packages for development such as roxygen2, devtools, usethis, and testthat. Once the code has been developed, the package is validated to ensure it passes all specifications using a combination of testthat and rmarkdown. Finally, the package is made available for use across the team on live data. These procedures set up a framework for validating assay processing packages that furthers the ability of Fred Hutch to provide world-class support for our clinical trials

Dr. Travis Gerke | UnicoRns are real | RStudio (2020)

Common advice from experienced data scientists to job-seekers is to avoid job postings that describe a “data science unicorn”: someone who has experience performing an unrealistically large array of technical and business-related job duties. Seeking a unicorn is viewed as a potential indicator that the company fails to understand their data science needs, and that new hires will not be poised for success due to lacking support and resources [Robinson & Nolis, 2019]. The R language, particularly when used with RStudio products, has evolved to enable production-level activities in the areas of data wrangling, reporting/dashboarding, database/software engineering, machine learning, and web application development. It is increasingly plausible that a data scientist will be able to efficiently perform a wide variety of job functions with experience only in a single language (R). Indeed, even entry level R users may tread into “unicorn” territory. Current standards for data scientist job descriptions and salaries do not accommodate this nuance, leaving both job-seekers and hiring managers unable to distinguish job requirements which should be read as warning signs from listings which are idyllic matches for the modern R unicorn. In this talk, we present data aggregated from several large compensation analytics companies which summarize current benchmarks for data science job descriptions and corresponding salary ranges. We then suggest job description language to target modern R users, considering both job duty compatibility and job post findability. These descriptions are presented with likely salary range pairings. Attention is given to deviations from traditional degree requirements, years of experience, and demands for multiple programming language literacy which may lack relevance for the R unicorn. Our overarching goal is to provide job description templates which encourage optimal matchmaking between R job seekers and organizations in need of their talents

Evangeline Reynolds | Flipbooks | RStudio (2020)

Good examples facilitate accomplishing new or unpracticed tasks in a programmatic workflow. Tools for communicating examples have improved in recent years. Especially embraced are tools that show code and its resultant output immediately thereafter — the case of Jupytr notebooks and Rmarkdown documents. But creators using these tools often must choose between big-picture or narrow-focus demonstration; creators tend to either demo a complete code pipeline that accomplishes a realistic task or instead demonstrate a minimal example which makes clear the behavior of a particular function, but how it might be used in a larger project isn’t clear. Flipbooks help address this problem, allowing the creator to present a full demonstration which accomplishes a real task, and gives the viewer the opportunity to focus on unfamiliar steps. A set of flipbook building functions parse code in a data manipulation or visualization pipeline and then build it back up incrementally. Aligned superimposition of new code and output atop previous code and output makes it easy to identify how each code change triggers changes in output. The presentation will guide attendees in creating their own Flipbooks (with Xaringan slides) or mini Flipbooks (gif output)

Danielle Navarro | Toward a grammar of psychological experiments | RStudio (2020)

Why does a psychological scientist learn a programming language? While motivations are many and varied the two most prominent are data analysis and data collection. The R programming language is well placed to address the first need, but there are fewer options for programming behavioural experiments within the R ecosystem. The simplest experimental designs can be recast as surveys, for which there are many options, but studies in cognitive psychology, psychophysics or developmental psychology typically require more flexibility. In this talk I outline the design principles behind xprmntr, an R package that provides wrappers to the a javascript library (jsPsych) for constructing web based psychology experiments and uses the plumber package to call server side R code as needed. In doing so, I discuss limitations to the current implementation and what a “grammar of experiments” might look like

Colin Gillespie | How to win an AI Hackathon, without using AI | RStudio (2020)

Anyone reading a newspaper or listening to the news is led to believe that AI is the solution to all problems. From self-driving cars to detecting disease to catching fraud, there doesn’t seem to be a situation that AI can’t tackle. Once “big data” is thrown into the mix, the AI solution is all but certain. But is AI always needed? Over the last eighteen months, Jumping Rivers has entered (and won) four Hackathons. All Hackathons were characterised with “big data” and the need to improve prediction. All Hackathons were won without using AI (or any sort of machine learning). This talk will focus on one particular competition around reducing leakage at Northumbrian Water. Using a combination of R, Shiny, and Tidyverse (and a few other tricks), we were able to demonstrate within the short Hackathon time frame that clear presentation of data to the front line engineers was more likely to reduce leakage, than simply providing vague estimates of a potential future leak

Braulio Cuandon & Ana Alyeska Santos | Using R to Create Reproducible Engineering Test Reports

Talk from rstudio::conf(2020) Engineers at Biosense Webster, a Johnson and Johnson medical device company that specializes in diagnosing and treating cardiac arrhythmias, write multiple test reports to comply with FDA regulatory standards. These intricate reports require 36 hours of an engineer’s time on average, constraining the engineers from completing investigations and studies in a timely matter. Writing scripts in R that create reproducible reports can significantly reduce the time spent by an engineer creating these reports allowing them to do a much thorough investigation with a larger scope. Through Shiny, engineers could conveniently have their parameters and recorded data processed and stored in a database by accessing a web link and filling out the required information within a user-friendly interface. Upon the generation of the report, accurate and properly formatted test reports, compliant to both the company and FDA regulatory standards, are produced through Rmarkdown and knitr knitting all the outputs with complete data analysis tools such as normality plots and process capability measurements to a word document that follows company required headers, footers, and headings. The reproducible report creation shown in this report can be extended to other types of test reports and protocols. The pilot phase that has been conducted has shown that complete report production has been decreased from 36 hours to an hour

This talk will focus on how we use R to develop reference implementations of visualizations (using ggplot2), and to develop corporate-themed color maps (using the colorspace package) to bring value to the entire institution. Color maps can be translated into variety of formats, for Tableau, Qlik Sense, d3, etc., and deployed independently from R. For visualizations, our goal is to translate ggplot2 objects to Vega-Lite specifications, using a package we are developing: ggvega. Vega-Lite visualizations are web-native, and are rendered independently from R. Specifications can be designed to be extensible to new data, allowing them serve as templates, to be deployed and updated for use outside of R. Of course, despite isolation within an institution, our work with the larger R open-source communities provides a foundation on which to build; in fact, we have a lot of company and are having a lot of fun

Mine Çetinkaya-Rundel | Making the Shiny Contest | RStudio (2020)

In January 2019 RStudio launched the first-ever Shiny contest to recognize outstanding Shiny applications and to share them with the community. We received 136 submissions for the contest and reviewing them was incredibly inspiring and humbling. In this talk, we shine a spotlight on the backstage: the inspiration behind the contest, the process of evaluation, what we learned about Shiny developers and how we can better support them, and what we learned about running contests and how we hope to improve the Shiny Contest experience. We also highlight some of the winning apps as well as the newly revamped Shiny Gallery, which features many noteworthy contest submissions. Finally, we introduce the new process for submitting your apps to the Shiny Gallery and, of course, to Shiny Contest 2020! https://rstudio.com/resources/rstudioconf-2020/making-the-shiny-contest/

Thomas Lin Pedersen | Extending your ability to extend ggplot2 | RStudio (2020)

The ggplot2 package continue to be one of the most used frameworks for producing graphics in R. While being extremely flexible, the package itself can be constrained by the different types of graphic elements and statistic transformations available. Instead of continuing to add new features, the development in recent years have focused on making ggplot2 extensible by other packages, thus distributing development and maintenance. Despite the best of intentions, ggplot2 can feel daunting to extend, due unusual idiosyncrasies, a foreign object system, and a partly obscured rendering model. This talk intend to remove the mystery of extending ggplot2, by describing the basic ways that it can be extended and showcasing a couple of simple extensions that can be build with very little code. Lastly, it will include discussions of some best practices and gotchas that may come in handy when you start out

Tyson Barrett | List-columns in data.table | RStudio (2020)

The use of list-columns in data frames and tibbles is well documented (e.g. Bryan, 2018), providing a cognitively efficient way to organize results of complex data (e.g. several statistical models, groupings of text, data summaries, or even graphics) with corresponding data. For example, one can store student information within classrooms, player information within teams, or analyses within groups. This allows the data to be of variable sizes without overly complicating or adding redundancies to the structure of the data. In turn, this can improve the reliability to appropriately analyze the data. Because of its efficiency and speed, being able to use data.table to work with list-columns would be beneficial in many data contexts (e.g. to reduce memory usage in large data sets). Herein, I demonstrate how one can create list-columns in a data table using the by argument in data.table and purrr::map(). I compare the behavior of the data.table approaches to the dplyr::group_nest() function and tidyr::unnest(), two of the several powerful Tidyverse nesting and unnesting functions. Results using bench::mark() show the speed and efficiency of using data.table to work with list-columns

Dr. Carson Sievert | Reproducible Shiny apps with shinymeta | RStudio (2020)

Shiny makes it easy to take domain logic from an existing R script and wrap some reactive logic around it to produce an interactive webpage where others can quickly explore different variables, parameter values, models/algorithms, etc. Although the interactivity is great for many reasons, once an interesting result is found, it’s more difficult to prove the correctness of the result since: (1) the result can only be (easily) reproduced via the Shiny app and (2) the relevant domain logic which produced the result is obscured by Shiny’s reactive logic. The R package shinymeta provides tools for capturing and exporting domain logic for execution outside of a Shiny runtime (so that others can reproduce Shiny-based result(s) from a new R session)

Ben Joaquin | Data Science in Meatspace | RStudio (2020)

“The Data Science community is dominated by folks doing amazing work with data that starts in and never leaves cyberspace. This talk is about best practices and playbooks for doing data science that involves meatspace (the opposite of cyberspace) and why R is such a great language for working with data that originated in the physical world. While the concrete examples in this talk will mostly come from the manufacturing space, where I have the most experience, I believe the themes are relevant to many meatspace workflows. We’ll talk through effective playbooks that can help you navigate common tasks throughout the life-cycle of a project. We’ll also weave in how R’s glorious package ecosystem, including Tidyverse, can be combined with other languages like python, and with enterprise products like RStudio Connect to great effect. Specifically, we’ll discuss practices in these areas: best practices for data collection in meatspace the importance of quantifying measurement system error collecting the correct data for training computer vision models the rarely discussed cost of maintaining models in production”

What should you name a new dinosaur discovery, according to neural networks? Which season of The Golden Girls should you watch when playing a drinking game? How can you build a LEGO set for the lowest price? R is constantly evolving, so as users, we’re constantly learning. Over the past few years, I’ve found that working on side projects is great for hands-on learning - and for me, the more absurd the project, the better. Side projects provide a safe, low-stakes environment to learn new packages and methodologies before using them in work or in production. Sharing those projects can help publicize the package and increase its accessibility, benefiting both the original author and future users. In this talk, I’ll share my experiences with side projects for learning state-of-the-art data science tools and growing as an R user, including how one project helped me land my dream job

Bryan Lewis | Parallel computing with R using foreach, future, and other packages | RStudio (2020)

Steve Weston’s foreach package defines a simple but powerful framework for map/reduce and list-comprehension-style parallel computation in R. One of its great innovations is the ability to support many interchangeable back-end computing systems so that the same R code can run sequentially, in parallel on your laptop, or across a supercomputer. Recent new packages like future package define elegant new programming approaches that can use the foreach framework to run across a wide variety of parallel computing systems. This talk introduces the basics of foreach and future packages with examples using a variety of back-end systems including MPI, Redis and R’s default parallel package clusters

Dr. Sydeaka Watson | Neural Networks for Longitudinal Data Analysis | RStudio (2020)

Longitudinal data (or panel data) arise when observations are recorded on the same individuals at multiple points in time. For example, a longitudinal baseball study might track individual player characteristics (team affiliation, age, height, weight, etc.) and outcomes (batting average, stolen bases, runs, strikeouts, etc.) over multiple seasons, where the number of seasons could vary across players. Neural network frameworks such as Long Short-Term Memory (LSTM) and Gated Recurrent Units (GRUs) can flexibly accommodate this data structure while preserving and exploiting temporal relationships. In this presentation, we highlight the use of neural networks for longitudinal data analysis with tensorflow and keras in R

Over the last few years, Rmarkdown seems to have taken over my life, or at least my written communication. These days I use Rmarkdown to maintain my website, write my blog, write textbooks, write academic papers, prepare slides for talks, keep my CV up-to-date, help my students write theses, prepare university policy documents, write letters, prepare exams, write reports for clients, and more. I haven’t quite got to the point of using it for shopping lists, but perhaps that’s my next Rmarkdown template. I will reflect on the journey in getting to this point, what I’ve lost and what I’ve gained. I will also speculate on what might be next in the Rmarkdownification of my life

Therese Anders | Peer review in data science courses | RStudio (2020)

Peer review enables instructors of large data science classes to provide substantive feedback to students beyond what is feasible with standard code review via automated grading and continuous integration. It facilitates peer learning, which is shown in literature to have positive learning outcomes, and can reduce the burden of grading by course staff. The ghclass package provides a suite of functions to manage courses via GitHub repositories. The package has recently been supplemented with the functionality to implement peer review. Developed during my 2019 summer internship with RStudio in collaboration with my mentor Mine Çetinkaya-Rundel, the peer review functions in ghclass interface with the GitHub API to create review repositories, move files between authors and reviewers, submit feedback, and collect grades. In this presentation, I will give a demonstration of the peer review functions in ghclass. A set of six functions allows instructors to 1) create a random review roster, 2) set up the review repository infrastructure within a GitHub organization, 3) move assignments from authors to reviewers, 4) collect grades, 5) return the feedback, and 6) obtain a rating of the review from the authors. I reflect on the pedagogy of implementing peer review in introductory data science classes and talk about lessons learned from a real-world test run of the package in the Fall semester 2019 at the University of Edinburgh, conducted by Mine Çetinkaya-Rundel. The presentation highlights ghclass as an R command-line based, open source, low profile, and powerful solution to enable peer review in classes ranging from a size of two to approximately 400 students.

Frank Harrell | R for Graphical Clinical Trial Reporting | RStudio (2020)

For clinical trials a good deal of effort goes into producing both final trial reports and interim reports for data monitoring committees, and experience has shown that reviewers much prefer graphical to tabular reports. Interactive graphical reports go a step further and allow the most important information to be presented by default, while inviting the reviewer to drill down to see other details. The drill-down capability, implemented by hover text using the R plotly package, allows one to almost entirely dispense with tables because the hover text can contain the part of a table that pertains to the reviewer’s current focal point in the graphical display, among other things. Also, there are major efficiency gains by having a high-level language for producing common elements of reports related to accrual, exclusions, descriptive statistics, adverse events, time to event, and longitudinal data. This talk will overview the hreport package, which relies on R, RMarkdown, knitr, plotly, Hmisc, and HTML5. RStudio is an ideal report development environment for using these tools

The path to becoming a world-class, data-driven organization is daunting. The challenges you will likely face along the way can be thorny, and in some cases, seem outright impossible to overcome. How do you get teams that traditionally butt heads, such as IT and data science, to complement each other and work in unison? How can you efficiently scale the scope and reach of your data products as requirements change? Your time should be spent doing truly valuable work instead of updating charts and reports. How do you prevent the support structure behind your platform from toppling like a house of cards? Despite these challenges, we think that the end result is worth it: an organization that is equipped to make important decisions, with confidence, using data analysis that comes from a sustainable environment.

Brendan Graham | Using R Bridge the Gap in Electronic Medical Record Reporting | Posit (2020)

Electronic Medical Records (EMRs) are a treasure trove of information, but tend to fall disappointingly short when it comes to visualizing and reporting data in a user friendly and intuitive manner. Building reports in an EMR can be a frustrating experience; the developer is at the mercy of how the data is stored within the EMR and the available EMR reporting tools can be bland and uninspiring. But reporting on data in the EMR doesn’t have to be this way! Combining the data-rich EMR with R’s robust reporting capabilities benefits both developers and consumers of data. This talk will describe how a cross-departmental project team uses an internal R package, RMarkdown reports scheduled via R Studio Connect, and an interactive flexdashboard app to quickly implement solutions to gaps in the reporting capabilities of the EMR. The flexibility of R relative to EMR reporting tools facilitates a design thinking approach to reporting allowing for more user input, customization and quick iteration. Furthermore, the web-based app we developed is able to be embedded within the EMR itself allowing for a more streamlined workflow

Lionel Henry | Interactivity and Programming in the Tidyverse | RStudio (2020)

In Tidyverse grammars such as dplyr you can refer to the columns in your data frames as if they were objects in the workspace. This syntax is optimised for interactivity and is a great fit for data analysis, but it makes it harder to write functions and reuse code. In this talk we present some advances in the tidy eval framework that make it easier to program around Tidyverse pipelines without having to learn a lot of theory

Colin Fay | Production-grade Shiny Apps with golem | RStudio (2020)

Shiny is an amazing tool when it comes to creating web applications with R. Almost anybody can get a small Shiny App in a matter of minutes, provided they have a basic knowledge of R. As of today, we can safely tell that it has become the de-facto tool for web application in the R world. Building a proof-of-concept application is easy, but things change when the application becomes larger and more complex, and especially when it comes to sending that app to production—until recently there hasn’t been any real framework for building and deploying production-grade Shiny Apps. This is where ‘golem’ comes into play: offering Shiny developers an opinionated framework for creating production-ready Shiny Applications. With ‘golem’, Shiny developers now have a toolkit for making a stable, easy-to-maintain, and robust for production web application with R. ‘golem’ has been developed to abstract away the most common engineering tasks (for example, module creation, addition of external CSS or JavaScript file, …), so you can focus on what matters: building the application. And once your application is ready to be deployed, ‘golem’ guides you through testing, and brings you tools for deploying to common platforms. In this talk, Colin and Vincent will present the ‘golem’ package, first talking about the “why ‘golem’?”, then presenting the general philosophy behind this framework, and help you get started building your first Shiny App with ‘golem’

Jared Lander | R: Then and Now | RStudio (2020)

R has changed a lot since the meetup was founded 10 years ago. Back then we were using base graphics (or lattice) and the apply family of functions and we didn’t have pipes. At the time there was an impressive 1800 packages on CRAN, now there are over 15,000 extending R’s reach far beyond its traditional domain of statistics and machine learning into publishing, website building and video generation. The community has grown and changed dramatically during that time, with the New York meetup alone going from 25 to over 10,000 members. During this talk we go through a then-and-now of R code and community to palpably see how everything has changed

William Chase | The Glamour of Graphics | RStudio (2020)

I see a lot of ugly charts. This is to be expected as I work with a lot of academics and data scientists, neither of whom have been trained in how to design attractive charts. I myself produced many ugly charts during my years as a research scientist, when the design process basically came down to random tweaking until things “looked good”. If only I could go back and tell young inexperienced me that there was a better way. In this talk, I will present that better way–a series of design principles that can take any chart from drab to fab. Rather than applying these techniques willy nilly, I will show how they form a layered “Glamour of Graphics” that is structured and can be easily applied to any chart. This Glamour of Graphics has some simple implementations in ggplot, where we will replace geoms, aesthetics, and scales with typography, color, and layout. Finally, I will discuss why looks matter when it comes to charts, and how by following the Glamour of Graphics you can design charts that are more persuasive and more accurately perceived

Nima Safaian | Rpanda trading simulation - from an idea to a multi-user shiny app | RStudio (2020)

The idea of rpanda commodities trading simulation was many years in the making. As energy trading professionals working in the industry, we had developed insights around how to make risk/reward market calls, and what skills make someone an exceptional commodities trader. Traders are one of the most expensive seats in terms of monetizing value from the assets. We developed rpanda as a simulated environment which replicates closely how real-life physical commodities trading works in order to assist talent development and selection, both in academics and enterprise. My co-founder and I did not know how to design production-ready software, but we always had used R/Shiny for market analysis in our corporate jobs. Rather than hiring expensive app developers, we decided to do it ourselves. We used Rstudio development stack such as Rstudio Connect and open source tools, like plumber to turn our idea into a production-ready app that is used by University of Alberta classes. In this presentation, we share our journey, technical challenges, and how we overcame them

Carl Howe & Greg Wilson | Data Science Education in 2022 | RStudio (2020)

More people are learning data science every day, and there are more ways for them to learn than ever before. To understand where we are and where we might be going, this talk looks at what data science education could look like two years from now: far enough away that we can dream, but close enough that we can only dream a little. We explore the balance between automated and collaborative learning, different ways to deliver different kinds of lessons to different kinds of people, and ways in which our tools and practices could improve

Lauren Chadwick | Meet You Where You R | RStudio (2020)

At RStudio, we wake up and go to bed thinking about the positive impact that open source work and data science has had and can have on the world. To maximize this impact, we find three areas of investment absolutely critical to ensure our open source community keeps up with the world’s changes and outlives us all: 1. Find ways to make R more approachable. 2. Enable teams of all types & sizes (educational, professional, etc.) to be able to leverage the work they’re doing in R, and effortlessly communicate that work to others. 3. Extend the language so our open-source community can continue to be at the forefront of innovation, no matter their preference of tool or language

Jesse Sadler | vctrs: Creating custom vector classes with the vctrs package | RStudio (2020)

The base R types of vectors enable the representation of an amazingly wide array of data types. There is so much you can do with R. However, there may be times when your data does not fit into one of the base types and/or you want to add metadata to vectors. vctrs is a developer-focused package that provides a clear path for creating your own S3-vector class, while ensuring that the classes you build integrate into user expectations for how vectors work in R. This presentation will discuss the why and how of using vctrs through the example of debkeepr, a package for integrating historical non-decimal currencies such as pounds, shillings, and pence into R. The presentation will provide a step-by-step process for developing various types of vectors and thinking through the design process of how vectors of different classes should work together

Even though I’ve completed 4 marathons, you certainly shouldn’t come to me for a training plan on how to achieve your goals for any race you’re about to run. So why do we often turn to “experienced R users” to help us learn R or train an organization? The RStudio certified trainers have been taught modern, evidence-based teaching practices which they use in planning training sessions in order to help delegates achieve THEIR learning goals effectively in a given time-frame. My talk will illustrate some of these teaching concepts and how, by becoming a certified trainer, you can help others learn about R more effectively.

Katherine Simeon | Every voice matters: An analysis of @WeAreRLadies | RStudio (2020)

As a rotating curation, @WeAreRLadies is a twitter account that has a different curator (i.e., tweeter) each week with a mission to highlight female and minority genders and their work in R. So far, curators have tweeted from 18 different countries and represent a variety of domains and levels of R expertise, ranging from R novices to those developing their own packages. With 45 R-Ladies curators to date, the account has become a popular R-related twitter resource, gaining more than 13,000 followers in the past year and hundreds of interactions each week. This talk will present a text analysis and reflection on over a year of Twitter text data from @WeAreRLadies. As the founder and maintainer of this account, I witness firsthand the bidirectional relationship between one’s learning journey and their use of R. In this talk, I will attempt to quantify this through a text analysis that explores how one’s experiences learning and using R relates to how they talk (or tweet) about it. By analyzing tweet text as well as other metrics provided by twitter (e.g., number of likes, replies, and clicks), I will showcase different ways curators have engaged with the R Twitter community and explore how account engagement has changed as the number of curators and followers continue to grow. I will also discuss how curators’ different areas of expertise have resulted in tweets and discussions that both demonstrate the variety of tools available in R, and spotlight unifying ideas and best practices in R programming. Finally, I will reflect on lessons learned and future directions for @WeAreRLadies, as well as its contribution to the R-Ladies Global initiative. Overall, this talk will discuss how diverse perspectives of @WeAreRLadies curators have enriched the conversations in the R Twitter community by validating different learning journeys and by promoting and amplifying underrepresented voices.

Javier Luraschi | Datasets in Reproducible Research with ‘pins’ | RStudio (2020)

Open source code is an essential piece in making science reproducible. Tools like ‘rmarkdown’ and GitHub facilitate running and sharing outcomes with colleagues and with the broad scientific community at large. However, it is less clear what tools should be used to retrieve, store and share datasets; while it is possible to make datasets part of your workflows today, it is usually hard and we are often left with manually sharing or downloading links to datasets. Not only that, but it’s also hard to share or discover datasets. In this talk we will introduce for the first time the ‘pins’ package. A package designed to: pin, discover and share resources. Meaning that, you can use ‘pins’ to simplify your data science workflows by easily fetching resources from GitHub, Kaggle, CRAN and RStudio Connect. We will present a ‘pin’ as a generic resource that can contain tabular datasets like CSVs, unstructured data like JSON files, image archives as ZIP files and so on. This talk will be highly interactive showing you how to get started by installing ‘pins’ from CRAN, retrieve and cache resources, share and discover useful and fun data resources to improve and enhance your day-to-day workflows

Hunter Glanz | The Five Principles of Data Science Education | RStudio (2020)

In this talk, I will outline a unified philosophy of data science education, and provide tips and tools for implementing these principles in the classroom using R and RStudio. Although data science as a professional discipline is well-established, its pedagogy is still in a period of growth. Even within a single university, multiple data science courses may be offered across different departments leading to inevitable redundancy of efforts amidst rich domain-specific innovations. My experience as an instructor in many such courses has lead me to five principles that transcend domain, context, and choice of language: reproducibility, communication, version control, practical application, and data ethics. For each of these full-stack themes, I will share examples of how to leverage tools in R and RStudio to enhance learning. A 5-minute presentation in our Lightning Talks series

Davis Vaughn | Sliding Windows and Calendars | RStudio (2020)

A number of R packages exist to make computing moving averages on a single numeric series straightforward. But generally “real” life is much messier than that! Try computing a moving average over a twenty-day sliding window when you have a time series with missing data. Oh! By the way, you should also skip over weekends when looking back twenty days. And you know that random holiday that your company celebrates that no one else does? Skip over that too. These are hard but realistic problems, and until now there has been a lack of tools necessary to solve them. In this talk, I’ll present two packages designed to tackle these issues, slide and almanac. slide is a package designed to perform arbitrary sliding window calculations. The simplest example of this would be a moving average. What makes slide unique is its support for sliding relative to an index, such as a date vector, which allows you to correctly compute the boundaries of that twenty day window. almanac is package for creating custom business calendars, and then adjusting dates relative to them. Inspired by lubridate, almanac allows you to shift dates by a set number of “business” days while respecting the weekends and holidays defined by a user-specified calendar. For example, shifting a Friday forward by 1 business day would land on a Monday, unless that Monday happened to be a holiday, in which case the next business day would actually be Tuesday. Together, slide and almanac provide the tooling necessary to solve the problem mentioned earlier. Additionally, because slide works with any arbitrary function, we can use the same procedure to compute rolling regressions, cumulative sums, and any other sliding computation.

Colin Rundel | livecode: broadcast your live coding sessions from and to RStudio | RStudio (2020)

In this talk we will demonstrate livecode, a new R package for broadcasting code for live code demonstrations. This package implements a simple webserver (using httpuv) to dynamically publishes the content of a code file (i.e..R or.Rmd) as you edit it live. This enables your students to have near realtime access to your code as you write it. The broadcast file can be viewed with any webbrowser but the package is specifically designed to be used within RStudio leveraging its builtin viewer. This gives students have direct access to the shared code within the IDE, allowing direct copying into their own source files and/or the console and thereby improving their ability to interact and experiment with your code.

Caroline Ledbetter | Rproject templates to automate and standardize your workflow | RStudio (2020)

Many teams and organizations have tasks and structures that are standard across projects. Lack of consistency and documentation can lead to lost productivity when team members join collaborations or previous work is consulted by your future self. Setting up folder structures can be particularly tedious. This talk will demonstrate using Rstudio project templates as part of an organizational package to automatically setup file structures, establish git repositories and add standardized readme files. It will also show how including report templates for Rmarkdown files can lead to more consistent and professional reports. Project info can be optionally stored so that project information can be easily added automatically to the top of reports and included in snippets for code file headers. Creating standard, easy to implement documentation and procedures can be particularly effective in encouraging skeptical collaborators to use git and Rmarkdown. Organizational packages can also be a great place to house functions that are specific and common to an organizations needs. The talk will showcase this functionality using the CIDAtools package that we developed. While the CIDAtools package was developed to address issues that sometimes arise from the less structured environment of academia, the tools presented can be equally useful in an industry setting.

RMarkdown enables analysts to engage with code interactively, embrace literate programming, and rapidly produce a wide variety of high-quality data products such as documents, emails, dashboards, and websites. However, RMarkdown is less commonly explored and celebrated for the important role it can play in helping R users grow into developers. In this talk, I will provide an overview of RMarkdown Driven Development: a workflow for converting one-off analysis into a well-engineered and well-designed R package with deep empathy for user needs. We will explore how the methodical incorporation of good coding practices such as modularization and testing naturally evolves a single-file RMarkdown into an R project or package. Along the way, we will discuss big-picture questions like “optimal stopping” (why some data products are better left as single files or projects) and concrete details such as the {here} and {testthat} packages which can provide step-change improvements to project sustainability

Open source R packages on GitHub often take advantage of continuous integration services to automatically check their packages for errors. This is very useful to catch things quickly, as well and increasing confidence for proposed changes, as the Pull Requests can be checked before they are merged. Travis-CI and Appveyor are the most popular current methods. However newer services, Azure Pipelines and GitHub Actions, show promise for being more powerful and simpler to configure and debug. I will discuss these services and demonstrate some of their capabilities and how to configure them for your own use in packages and reports

George Kastrinakis | Building a data science pipeline for the FT with RStudio Connect | RStudio

Talk from rstudio::conf(2020) We have recently implemented a new Data Science workflow and pipeline, using RStudio Connect and Google Cloud Services. This has vastly decreased our pipeline complexity, allowing us to bring our models and products into scheduled production more quickly. In addition, our workflow, working closely together as a team on all projects on a regular two-week sprint cycle, has increased the range of projects we have been able to take on and complete. To detail some of the key lessons we’ve learned (and some of the difficulties!), we’ll walk you through one of our recent sprints, where we productionalised the generation of a suite of behavioural and demographic features so that they can be more easily plugged in to a range of models and used across the business by the FT’s platform and product teams

Sharla Gelfand | Don’t repeat yourself, talk to yourself! Reporting with R | RStudio (2020)

If you’re responsible for analyses that need updating or repeating on a semi-regular basis, you might find yourself doing the same work over and over again. The principle of “don’t repeat yourself” from software engineering motivates us to use functions and packages, the core of repetition in the R universe. For analyses, it can be difficult to know how to use this principle and move beyond “copying and pasting scripts and changing the data file and the object names and updating the dates and results in RMarkdown”, especially when there’s some element of human intervention required, whether it be for validating assumptions or cleaning artisanal data. This talk will focus on those next steps, showcasing opportunities to stop repeating yourself and instead anticipate the needs of and communicate effectively with your future self (or the next person with your job!) using project-oriented workflows, clever interactivity, templated analyses, functions, and yes, your own packages

Ian Cook | Bridging the Gap between SQL and R | RStudio (2020)

Ian Cook | January 31, 2020 Like it or not, SQL is the closest thing we have to a universal language for working with structured data. Celebrating its 50th birthday in 2020, SQL today integrates with thousands of applications and has millions of users worldwide. Data analysts using SQL represent a large audience of potential R users motivated to expand their data science skills. But learning R can be frustrating for SQL users. One major frustration is the inability to directly query R data frames with SQL SELECT statements. Eager to use R for tasks that are not possible with SQL (like data visualization and machine learning), these users are dismayed to find that they must first learn an unfamiliar syntax for data manipulation. The popularity of the sqldf package (which automatically exports an R data frame into an embedded database, then runs a SQL query on it) demonstrates this frustration. But now there is a way to directly query an R data frame without moving the data out of R. In this talk, I introduce tidyquery, a new R package that runs SQL queries directly on R data frames. tidyquery is powered by dplyr and by queryparser, a new pure-R, no-dependency SQL query parser

Winston Chang | Asynchronous programming in R | RStudio (2020)

Writing regular R code is straightforward: you tell R to do something, it does it, and then it returns control back to you. This is called synchronous programming. However, if you use R to coordinate threads, processes, or network communication, the regular model may be unable to do what you want, or it may only be able to do it with a significant performance penalty. In this talk I'll explain how asynchronous programming with the later package can handle these kinds of programming problems. I'll also show how to provide a synchronous interface for asynchronous code, so that users will have a simple, familiar way to use your code. Materials - github repo

Nick Strayer | Stochastic Block Models with R: Statistically rigorous clustering | RStudio (2020)

Nick Strayer | January 31, 2020 Often a machine learning research project starts with brainstorming, continues to one-off scripts while an idea forms, and finally, a package is written to disseminate the product. In this talk, I will share my experience rethinking this process by spreading the package writing across the whole process. While there are cognitive overheads involved with setting up a package framework, I will argue that these overheads can serve as a scaffolding for not only good code but robust research practices. The result of this experiment is the SBMR package: a native R package written to fit and investigate the results of Bipartite Stochastic Block Models that forms the backbone of my PhD dissertation. By going over the ups and downs of this process, I hope to leave the audience with inspiration for moving the package writing process closer to the start of their projects and melding research and code more closely to improve both

Kelly O’Briant | Configuration management tools for the R admin | RStudio (2019)

This talk will feature an introduction to configuration management tools for the Analytic Administrator. An analytic admin is someone who is invested in continually improving analytic infrastructure, advocates for best practices in data product deployments, and acts to adopt DataOps philosophies in their organization. One of the biggest challenges for an analytic admin can be figuring out how to help IT groups develop core competencies around the management of R tooling. When IT groups are unfamiliar with R, they might lean heavily on the analytic admin for guidance or resist adoption entirely. Data science teams that rely on delivering results through integrated R based solutions can get blocked when they lack the full support of IT. I’ll present a roadmap for how analytic admins can create custom teaching tools for introducing the R toolchain. Using these strategies, a dash of creativity, and a little bit of empathy, I hope you can get the IT buy-in you’ll need to make R a fully legitimate part of your organization.

Amelia McNamara | Working with categorical data in R without losing your mind | RStudio (2019)

Categorical data, called “factor” data in R, presents unique challenges in data wrangling. R users often look down at tools like Excel for automatically coercing variables to incorrect datatypes, but factor data in R can produce very similar issues. The stringsAsFactors=HELLNO movement and standard tidyverse defaults have moved us away from the use of factors, but they are sometimes still necessary for analysis. This talk will outline common problems arising from categorical variable transformations in R, and show strategies to avoid them, using both base R and the tidyverse (particularly, dplyr and forcats functions). VIEW MATERIALS http://www.amelia.mn/WranglingCats.pdf (related paper from the DSS collection) http://bitly.com/WranglingCats https://peerj.com/collections/50-practicaldatascistats/ About the Author Amelia McNamara My work is focused on creating better tools for novices to use for data analysis. I have a theory about what the future of statistical programming should look like, and am working on next steps toward those tools. For more on that, see my dissertation.

Emily Robinson | Building an AB testing analytics system with R and Shiny | RStudio (2019)

Online experimentation, or A/B Testing, is the gold standard for measuring the effectiveness of changes to a website. While A/B testing is used at tens of thousands of companies, it can seem difficult to parse without resorting to expensive end-to-end commercial options. Using DataCamp’s system as an example, I’ll illustrate how R is actually a great language for building powerful analytical and visualization A/B testing tools. We’ll first dive into our open-source funneljoin package, which allows you to quickly analyze sequential actions using different types of behavioral funnels. We’ll then cover the importance of setting up health checks for every experiment. Finally, we’ll see how Shiny dashboards can help people monitor and quickly analyze multiple A/B tests each week.

Hilary Parker | Cultivating creativity in data work | RStudio (2019)

Traditionally, statistical training has focused primarily on mathematical derivations, proofs of statistical tests, and the general correctness of what methods to use for certain applications. However, this is only one dimension of the practice of doing analysis. Other dimensions include the technical mastery of a language and tooling system, and most importantly the construction of a convincing narrative tailored to a specific audience, with the ultimate goal of them accepting the analysis. These “softer” aspects of analysis are difficult to teach, perhaps more so when the field is framed as mathematics and often housed in mathematics departments. In this talk, I discuss an alternative framework for viewing the field, borrowing upon the past work in other fields such as design. Looking forward, we as a field can borrow from these fields to cultivate and hone the creative lens so necessary to the success of applied work.

Angela Bassa | Data science as a team sport | RStudio (2019)

How do you data science as a team sport? Oftentimes a data scientific initiative starts with just a single, lonesome data scientist. But when that germ of a team is successful and starts expanding, should the team be embedded in other disciplines or should it be centralized into its own function? Where should it live in the organizational structure? Should you focus on recruiting senior data scientists or is there a benefit to attracting junior talent as well? And in terms of capabilities, should you hold out for unicorns or hire several specialists to get all jobs done? Data scientists need to work on almost every aspect of a business, so how should a team composition set the data science discipline up for success? Great data scientists have career options and won’t abide bad managers for very long: if you want to retain them, you’ll need to care about their work, connect it to the business, and design a diverse, resilient, high-performing team.

Eric Nantz | Effective use of Shiny modules in application development | RStudio (2019)

As a Shiny application grows in scale, organizing code into reusable and streamlined components becomes vital to manage future enhancements and avoid unnecessary duplication. Shiny modules are customized R functions that are easily reused multiple times within an application by avoiding namespace collisions and assist with organizing the code base. Like R functions, modules can be simple utilities or elaborate pieces with multiple inputs and outputs. While the process of creating a module is uncomplicated, application developers can quickly encounter challenges including communication among modules, defining logical compositions, and avoiding hidden state modifications. In this talk, we will introduce practical principles and techniques developers can leverage to address these issues head-on such as documenting modules, passing parameters and return values effectively between modules, and how nesting modules enables dynamic user interfaces with minimal overhead.

Amanda Gadrow | Getting it right: Writing reliable and maintainable R code | RStudio (2019)

How can you tell that your scripts, applications, and package functions are working as expected? Are you sure that when you make changes in one part of the code, it won’t break something in another part? Have you thought deeply about how the consumers of your code (including Future You) will use it, maintain it, fix it, and improve it? Code quality is essential not only for reliable results but also for your script’s maintainability and your users’ satisfaction.

Thomas Lin Pedersen | gganimate live cookbook | RStudio (2019)

Animation of data visualisation is becoming increasingly popular both as an attention grabber on social media and as a way to tell small data stories. gganimate is a package that extends ggplot2 for making animations and provides a grammar of animation on top of the grammar of graphics. This talk will quickly introduce gganimate, and then dive into a series of different animation and show how they were made and how they could be changed or expanded.

Alan Dipert | Integrating React.js and Shiny | RStudio (2019)

React.js is a thriving JavaScript library that eases encapsulating and sharing sophisticated component libraries. The React.js ecosystem is filled with components for doing everything from color selection (react-color) to animation (react-spring). While it’s always been technically possible to integrate React.js components with Shiny applications, it hasn’t always been particularly obvious how. To make it easier, we augmented the excellent reactR package with functions specifically designed to make it easier to create new htmlwidgets, inputs, and outputs based on React.js components. In this talk, I will further motivate and demonstrate these new tools and do my best to empower the audience to try them out. About the Author Alan Dipert Alan is a software engineer on the Shiny team at RStudio. In the past, he’s helped build web applications, reporting pipelines, and many things between. When he’s not working, Alan likes to spend his time reading or being with his family

Jim Hester | It depends: A dialog about dependencies | RStudio (2019)

Software dependencies can often be a double-edged sword. On one hand, they let you take advantage of others’ work, giving your software marvelous new features and reducing bugs. On the other hand, they can change, causing your software to break unexpectedly and increasing your maintenance burden. These problems occur everywhere, in R scripts, R packages, Shiny applications and deployed ML pipelines. So when should you take a dependency and when should you avoid them? Well, it depends! This talk will show ways to weigh the pros and cons of a given dependency and provide tools for calculating the weights for your project. It will also provide strategies for dealing with dependency changes, and if needed, removing them. We will demonstrate these techniques with some real-life cases from packages in the tidyverse and r-lib.

Jenny Bryan | Lazy evaluation | RStudio (2019)

The “tidy eval” framework is implemented in the rlang package and is rolling out in packages across the tidyverse and beyond. There is a lively conversation these days, as people come to terms with tidy eval and share their struggles and successes with the community. Why is this such a big deal? For starters, never before have so many people engaged with R’s lazy evaluation model and been encouraged and/or required to manipulate it. I’ll cover some background fundamentals that provide the rationale for tidy eval and that equip you to get the most from other talks.

Jesse Sadler | Learning and using the tidyverse for historical research | RStudio (2019)

My talk will discuss how R, the tidyverse, and the community around R helped me to learn to code and create my first R package. My positive experiences with the resources for learning R and the community itself led me to create a blog detailing my experiences with R as a way to pass along the knowledge that I gained. The next step was to develop my first package. The debkeepr package integrates non-decimal monetary systems of pounds, shillings, and pence into R, making it possible to accurately analyze and visualize historical account books. It is my hope that debkeepr can help bring to light crucial and interesting social interactions that are buried in economic manuscripts, making these stories accessible to a wider audience.

I received a Ph.D. in European History from UCLA in 2015 and have taught courses on cultural and intellectual history of early modern Europe and the Atlantic. My research investigates the familial basis of the early modern capitalism through archival research on two mercantile families from Antwerp at the end of the sixteenth and beginning of the seventeenth century. I am currently working on a manuscript that argues for the significance of sibling relationships and inheritance in the development of early modern trade. My manuscript places concepts such as patriarchy, emotion, exile, and friendship at the heart of the efficacy of long-distance trade networks and the growth of capitalism

Miles McBain | Our colour of magic The open sourcery of fantastic R packages | RStudio (2019)

What does it mean to say software is, to quote one Twitter user, ‘so f***ing magical!’? In the context of our popular community hobby of rating and sharing R packages, the term ‘magic’ seems reserved for our most powerful expressions of visceral approval. Why is this? And what does it say about how we value software? Can this magical quality be quantified? We will consider these questions in examination of magical specimens, and in the process reveal the surprising depths at which notions of magic are embedded in the R zeitgiest.

Gabor Csardi | pkgman A fresh approach to package installation | RStudio (2019)

The main goals of pkgman is to make package installation fast and more reliable. This allows new, simpler and safer workflows, such as separate package libraries for projects. In this talk, we will show the features that make pkgman fast, convenient and reliable. Features that make pkgman fast: * Concurrency: pkgman performs all downloads, package builds and installations concurrently by default. * Metadata and package cache: pkgman caches all metadata and all downloaded and locally built packages in its cache. * Lazyness: pkgman only downloads and installs packages if needed. Features that make pkgman convenient: * BioC and GitHub packages are supported seamlessly. * Informative UI. pkgman can lay out the installation/update plan, that the user needs to confirm. It returns data about downloads, builds, installations, etc. Features that make pkgman reliable: * Dependency solver. pkgman makes sure that you end up in consistent, working state of dependencies. * Private library: pkgman’s own dependencies do not affect your regular package library, and vice versa. pkgman does not load any packages from your regular library.

Brooke Watson | R at the ACLU Joining tables to to reunite families | RStudio (2019)

Last year, over 2500 immigrant children were separated from their family while in government custody. Information about their status is scattered across several government agencies, and throughout the national class-action lawsuit “Ms. L vs ICE,” the Analytics team of the ACLU has been using R to join, deduplicate, validate, and analyze it. Using specifics of this case, this talk will address common challenges arising from human-generated data in spreadsheets. With generalizable examples, I will discuss data tidying, standardization, deduplication, and validation using the tidyverse, janitor, assertthat, and other packages. Finally, I will share best practices for requesting useful data from non-quantitative subject matter experts. About the Author Brooke Watson I am a Data Scientist at the ACLU, where I use code and statistics to support civil rights litigation and advocacy.

Joe Rickert | R Consortium initiatives in medicine | Posit (2019)

R / Pharma and R / Medicine, two new R Consortium sponsored conferences that appeared in 2018, are both grass roots, community-level manifestations of fundamental trends driving the growth of R. R / Pharma organized as an R Consortium working group by R users at several prominent pharmaceutical companies demonstrated that R has reached sufficient critical mass in Pharma to be recognized as a technology important enough to explore inter-company cooperation, while the addition of Genetech/Roche to R Consortium shows the commitment of upper level management to migrate from SAS to R. - At the other, non-corporate end of the spectrum, the R / Medicine conference was well attended by practicing clinicians coming to R, and in some cases statistics and data analysis, for the first time in order to move forward with the practice of data driven medicine. - In this talk, I will present some highlights from these conferences, and other related R Consortium initiatives, describe some of the R-based projects that illustrate the kind of work being done, and indicate what to expect this year.

Karl Broman | R qtl2 Rewrite of a very old R package | RStudio (2019)

For nearly 20 years, I’ve been developing, maintaining, and supporting an R package, R/qtl, for mapping quantitative trait loci (genetic loci that contribute to variation in quantitative traits, such as blood pressure) in experimental crosses (such as in mice). It’s a rather large package, with 39k lines of R code, 24k lines of C code, and nearly 300 user-accessible functions. In the past several years, I’ve been working on rewriting the package, to better handle high-dimensional data and more complex experimental crosses. This has been a good opportunity to take advantage of many new tools, including Rcpp, Roxygen2, and testthat. I’ll describe my efforts to avoid repeating the mistakes I made the first time around.

Edzer Pebesma | Spatial data science in the Tidyverse | RStudio (2019)

Package sf (simple feature) and ggplot2::geom_sf have caused a fast uptake of tidy spatial data analysis by data scientists. Important spatial data science challenges are not handled by them, including raster and vector data cubes (e.g. socio-economic time series, satellite imagery, weather forecast or climate predictions data), and out-of-memory datasets. Powerful methods to analyse such datasets have been developed in packages stars (spatiotemporal tidy arrays) and tidync (tidy analysis of NetCDF files).

During my summer internship at RStudio, I worked with Jenny Bryan to develop a series of data science puzzles known as the “Tidies of March.” These puzzles isolate data wrangling tasks into bite-sized pieces to nurture core data science skills such as importing, reshaping, and summarizing data. We also provide access to puzzles and puzzle data directly in R through an accompanying Tidies of March package. I will show how this package models best practices for both data wrangling and project management. VIEW MATERIALS https://github.com/isteves/ds-puzzles About the Author Irene Steves This summer I was an intern at RStudio, where I worked with Jenny Bryan to develop a series of coding challenges to cultivate and reward the mastery of R and the tidyverse. I was previously a Data Science Fellow at the National Center for Ecological Analysis and Synthesis (NCEAS), where I reviewed data submissions to a national repository for completion, clarity, and data management best practices. As a fellow, I also collaborated on a number of open science projects to improve access to Ecological Metadata Language (EML) and datasets in the DataONE network (see metajam, dataspice)

Nic Crane | The future’s Shiny: Pioneering genomic medicine in R | Posit (2019)

Shiny’s expanding capabilities are rapidly transforming how it is used in an enterprise. This talk details the creation of a large-scale application, supporting hundreds of concurrent users, making use of the future and promises packages. The 100,000 genomes project is an ambitious exercise that follows on from the Human Genome Project - aiming to put the UK at the forefront of genomic medicine, with the NHS as the first health service in the world to offer precision medicine to patients with rare diseases and cancer. Data is at the heart of this project; not only the outputs of the genomic sequencing, but vast amounts of metadata used to track progress against the 100,000 genome target and the status and path of each case through the sample tracking pipeline. In order to make this data readily available to stakeholders, Shiny was used to create an application containing multiple interactive dashboards. A scaled-up version of the app is being rolled out in early 2019 to a much larger audience to support the National Genomics Informatics Service, with the challenge of creating a complex app capable of supporting so many users without grinding to a halt. In this talk, I will explain why Shiny was the obvious technology choice for this task, and discuss the design decisions which enabled this project’s success.

Carl Howe | The next million R users | RStudio (2019)

Many students believe that R is obscure, complex, and difficult to write. However, data from a new large-scale survey of R users conducted by RStudio shows that new R users are taking dramatically different learning paths from those who learned R as recently as 2 years ago, and these new learning paths are changing its perception. In this talk, we’ll present this new survey data, describe how new tools and techniques for teaching R can satisfy the demands of today’s R learners, and outline a vision for adding millions of new R users to our community.

David Robinson | The unreasonable effectiveness of public work | RStudio (2019)

In this talk, I’ll lay out the reasons that blogging, open source contribution, and other forms of public work are a critical part of a data science career. For beginners, a blog is a great accompaniment to data science coursework and tutorials, since it gives you experience applying practical data science skills to real problems. For data scientists at any stage of their careers, open source development offers practice in collaboration, documentation, and interface design that complement other kinds of software development. And for data scientists more advanced in their careers, writing a book is a great way to crystallize your expertise and ensure others can build on it. All of these practices build skills in communication and collaboration that form an essential component of data science work. Each also lets you build a public portfolio of your skills, get feedback from your peers, and network with the larger data science community.

Earo Wang | Melt the clock Tidy time series analysis | RStudio (2019)

Time series can be frustrating to work with, particularly when processing raw data into model-ready data. This work presents two new packages that address a gap in existing methodology for time series analysis (raised in rstudio::conf 2018). The tsibble package supports organizing and manipulating modern time series, leveraging tidy data principles along with contextual semantics: index and key. The tsibble data structure seamlessly flows into forecasting routines. The fable package is a tidy renovation of the forecast package. It promotes transparent forecasting practices and concise model representations, to empower analysts tackling a broad domain of forecasting problems. This collection of packages form the tidyverts, which facilitates a fluent and fluid workflow for analyzing time series.

Felienne | Explicit Direct Instruction in Programming Education | RStudio (2019)

In education, there is and has always been debate about how to teach. One of these debates centers around the role of the teacher: should their role be minimal, allowing students to find and classify knowledge independently, or should the teacher be in charge of what happens in the classroom, explaining students all they need to know? These forms of teaching have many names, but the most common ones are exploratory learning and direct instruction respectively. While the debate is not settled, more and more evidence is presented by researchers that explicit direct instruction is more effective than exploratory learning in teaching language and mathematics and science. These findings raise the question whether that might be true for programming education too. This is especially of interest since programming education is deeply rooted in the constructionist philosophy, leading many programmers to follow exploratory learning methods, often without being aware of it. This talk outlines this history of programming education and additional beliefs in programming that lead to the prevalence of exploratory forms of teaching. We also explain the didactic principles of direct instruction, explore them in the context of programming, and hypothesize how it might look like for programming

Yihui Xie | pagedown Creating beautiful PDFs with R Markdown and CSS | RStudio (2019)

The traditional way to beautiful PDFs is often through LaTeX or Word, but have you ever thought of printing a web page to PDF? Web technologies (HTML/CSS/JavaScript) are becoming more and more amazing. It is entirely possible to create high-quality PDFs through Google Chrome or Chromium now. Web pages are usually single-page documents, but they can be paginated thanks to the JavaScript library Paged.js, so that you can have elements like headers, footers, and page margins for the printing purpose. In this talk, we introduce a new R package, pagedown ( https://github.com/rstudio/pagedown), to create PDF documents based on R Markdown and Paged.js. Applications of pagedown includes, but not limited to, books, articles, posters, resumes, letters, and business cards. With the power of CSS and JavaScript, you can typeset your documents with amazing elegance (e.g., a single line of CSS, “tr:nth-child(even) { background: #eee; }”, will give you a striped table, and “border-radius: 50%;” gives you a circular element) and power (e.g., HTML Widgets).

Matt Dancho | Using R, the Tidyverse, H2O, and Shiny to reduce employee attrition | RStudio (2019)

An organization that loses 200 high-performing employees per year has a lost productivity cost of about $15M/year. This cost is massive, yet many organizations don’t know it exists. It doesn’t show up on a financial statement. Therefore, it goes unnoticed. This presentation showcases how several open source tools integrate to form a solution to the employee attrition problem. Specifically: (1) How the tidyverse enables problem identification through visualization. (2) How recipes + H2O can be combined to explain key relationships to attrition and predict employee attrition. (3) How Shiny can be used to create a powerful dashboard that empowers business leaders to make data-driven decisions across the organization

Claus Wilke | Visualizing uncertainty with hypothetical outcomes plots | RStudio (2019)

Uncertainty is a key component of statistical inference. However, uncertainty is not easy to convey effectively in data visualizations. For example, viewers have a tendency to interpret visualizations of the most likely outcome as the only possible one. Viewers may also misjudge the likelihood of different possible outcomes or the extent to which moderately rare outcomes may deviate from the expectation. One way in which we can help the viewer grasp the amount of uncertainty present in a dataset is by showing a variety of different possible modeling outcomes at once. For example, in a linear regression, we could plot a number of different regression lines with slopes and intercepts drawn from the range of likely values, as determined by the variation in the data. Such visualizations are called Hypothetical Outcomes Plots (HOPs). HOPs can be made in static form, showing the various hypothetical outcomes all at once, or preferably in an animated form, where the display cycles between the different hypothetical outcomes. With recent progress in ggplot2-based animation, via gganimate, as well as packages such as tidybayes that make it easy to generate hypothetical outcomes, we can easily produce animated HOPs in a few lines of R code. This presentation will cover the key concepts, packages, and techniques to generate such visualizations.

Sigrid Keydana | Why TensorFlow eager execution matters | RStudio (2019)

In current deep learning with Keras and TensorFlow, when you’ve mastered the basics and are ready to dive into more involved applications (such as generative networks, sequence-to-sequence or attention mechanisms), you may find that surprisingly, the learning curve doesn’t get much flatter. This is largely due to restrictions imposed by TensorFlow’s traditional static graph paradigm. With TensorFlow Eager Execution, available since summer and announced to be the default mode in the upcoming major release, model architectures become more flexible, readable, composable, and last not least, debuggable. In this session, we’ll see how with Eager, we can code sophisticated architectures like Generative Adversarial Networks (GANs) and Variational Autoencoders (VAEs) in a straightforward way.

Advanced R Markdown 2-day Workshop - rstudio::conf(2019L)

What is the 2-day Advanced R Markdown Workshop? That’s a great question, I’m glad you asked. This is a two-day hands-on workshop based on the book “R Markdown: The Definitive Guide”. This workshop is designed for those who want to take their R Markdown skills to the next level. We’ll talk about many low-level details in the rmarkdown package and the whole R Markdown ecosystem. The two goals of this workshop are: 1) learn how to fully customize R Markdown output (HTML, LaTeX/PDF, Word, and PowerPoint); and 2) learn more about existing R Markdown extensions in the ecosystem, such as flexdashboard, bookdown, blogdown, pkgdown, xaringan, rticles, and learnr. We will also talk about how to use or develop new language engines (languages that are not R), how to develop HTML widgets, and integrate Shiny with R Markdown. You should take this workshop if you have experience programming in R and want to learn how to take advantage of the amazing breadth and depth of R Markdown. You’ll get the most from it if you enjoy learning how R Markdown works under the hood (which will involve reading some source code), and are seriously interested in hacking (playing) with HTML, JavaScript, CSS, LaTeX, and command-line tools. We will give minimal tutorials on these languages and tools in the workshop, but it may be easier for you to keep pace with the instructor if you already know them before. This workshop is led by Yihui Xie, Software Engineer and Data Scientist at RStudio. Yihui is the main author of the open-source knitr package for reproducible research and dynamic report generation. He has also created and co-authored several other R packages, including rmarkdown, bookdown, blogdown, xaringan, tinytex, DT, shiny, and leaflet. He has authored and co-authored four books: Dynamic Documents with R and knitr, bookdown: Authoring Books and Technical Documents with R Markdown, blogdown: Creating Websites with R Markdown, and R Markdown: The Definitive Guide.

Three commons ways to use the term. noun, a reproducible example the reprex package. a tool to build R reprexs reprex::reprex(), a function in reprex to make a reprex. 5:26 When should you use a reprex? 6:14 reprex installation and setup. How do you actually get repex on your machine? 7:59 Advanced setup and discussion. 9:45 Please use advanced features responsibly. 11:02 Why does the reprex package exist? Anyone who has helped teach R or dealt with github issues, twitter, stack overflow & RStudio community questions knows that helping people diagnose their coding problems can be hard. This tool comes from hard-won experience. It’s aim to is help people ask well formed questions and increase the chances of getting well formed answers quickly. 12:52 philosophy behind reprex code that I can run code that I don’t need to run code that I can easily run 13:52 code that I can run. 17:25 Tips on writing good reprexs. Dos and don’ts. 18:52 How do I get my data into my reprex? Getting small data and CSV type data into your reprex is easy. “I have a big hairy data object and I can only show their problem by using it”, but that’s not always the case. 21:02 code that I don’t need to run reprex gives your reader the code and reveals the output being produced by that code. For experienced coders, that might be enough to help you. 22:44 code that I can easily run Don’t copy and paste from the R console. This is usually annoying for your reader. Worse than console copy-pasta is the screenshot. (Many people think screenshots of code are downright offensive.) 25:03 reprex_clean If you copy someone else’s reprex into your consolve, it may include their output, making your new reprex a untidy. Here are tips for taking someone else’s reprex code and output, and create a clean reprex reply. 25:54 shock and awe More interesting features of the reprex package. 26:29 What about figures and plots in your reprex? So happy you asked about that. reprex will automatically upload your images to imgur.com. 28:23 Create a reprex by explicitly providing your code in the reprex call. 29:00 when you need your reprex to work in the current working directory. 30:45 Differently flavored markdown. Optimize your reprex markdown output for github, stack overflow, or the RStudio community. 30:31 Make your reprex create an R script, with your reprex outputs as comments. This is handy for pasting into an email or slack-type-app. 32:25 Rich text format, rtf output. (currently experimental feature as of this video) 33:06 supress the reprex add at the bottom of your reprex 33:19 Include session info. 33:54 Auto styling of your code. Good if you’re dealing with poorly formatting code. 34:25 Change your comments string. 34:32 Silence Tidyverse startup messages. 35:00 Capture a reprex that sends messages to standard output and standard input (e.g. package installation compilation messages). 36:13 Set up personal defaults for your reprex usage. 36:54 reprex RStudio addins; render reprex and reprex selection. These accelerate your use of reprex. 39:01 The human side of reproducible examples. How to ask questions in ways that are most likely to get answered. Sorry for the tough love, but this is important. Why are you always asked to give a reprex? Experts try to use reproducible examples to ensure their advice works. Making a good reprex is hard. But, you are asking them to solve a problem for you, so meet them halfway. Creating reprexes is good coding practice. Making a good reprex is often a good way to debug your issue in the embarrassment-free privacy of your own home. reprexes lead to discussions more likely to help people in the future. 44:34 Behind the scenes of reprex 44:44 Thanks for those that helped make reprex possible. Questions and Answers 46:05 can reprex capture variables and objects in the current environment? (not yet, maybe in development) 47:25 does reprex actually check that the code is self contained? (self contained) 48:08 does readr::read_csv support the text argument? (yep, just read the help manual for readr)

Interacting with Databases by Bárbara Borges from Shiny from useR! Brussels 2017

Connecting to an external database from R can be challenging. This is made worse when you need to interact with a database from a live Shiny application. To demystify this process, I’ll do two things. First, I’ll talk about best practices when connecting to a database from Shiny. There are three important packages that help you with this and I’ll weave them into this part of the talk. The DBI package does a great job of standardizing how to establish a connection, execute safe queries using SQL (goodbye SQL injections!) and close the connection. The dplyr package builds on top of this to make even easier to connect to databases and extract data, since it allows users to query the database using regular dplyr syntax in R (no SQL knowledge necessary). Yet a third package, pool, exists to help you when using databases in Shiny applications, by taking care of connection management, and often resulting in better performance. Second, I’ll demo these concepts in practice by showing how we can connect to a database from Shiny to create a CRUD application. I will show the application running and point out specific parts of the code (which will be publicly available)
