2023 Posit Year in Review

Year in Review 2023. A collage of cartoon people looking out into the open.

From exciting product updates to insightful discussions in our weekly hangouts, the past year has been filled with growth and learning. Join us as we revisit significant highlights for our community over the last 12 months.


Posit and the community


In September, we concluded the first posit::conf. Whether you attended online or in person in Chicago, we’re glad you were part of it.

We’ve kept the momentum going with our weekly Data Science Hangouts series, gaining valuable insights from industry leaders. Additionally, we introduced a new series called End-to-End Data Science Workflows, demonstrating the creation of analytic platforms that facilitate open-source data science. Watch three reasons you should join the event.

2023 was a year of celebration of the adoption of R in the pharmaceutical industry, from webinars with Roche and Novo Nordisk to the marking of five years of R/Pharma. We had the opportunity to share several success stories, such as Eric Nantz, Director of the Statistical Innovation Center at Eli Lilly and Company, discussing how he has seen Shiny create value in the clinical trials process.

  • Typst format: Typst is a new open-source markup-based typesetting system that is designed to be as powerful as LaTeX while being much easier to learn and use. Watch a posit::conf talk on Typst, presented by Carlos Scheidegger.
  • Email, Shiny for Python, lightbox treatment, and more.

Stay tuned for the 1.4 announcement on the Quarto blog!


RStudio Desktop


RStudio Desktop (the free IDE) had a fantastic year, introducing new user guides, enhanced auto-completion and accessibility features, and more. Additionally, AI-related tools like GitHub Copilot support in the IDE and the chattr package, offering an interface to Large Language Models (LLMs), are now available.




Shiny is a tool for making web apps with R or Python, no web development skills required. Shiny for R received many exciting updates, including dark mode, tooltips, and popovers. The ShinyUiEditor has also transitioned out of alpha, making it easier for you to design your Shiny UI.

Last year, we announced Shinylive, a tool for running Shiny for Python directly in the browser. Thanks to the magic of webR (more on webR below), Shinylive is also available in R. That means R users can also run Shiny apps in the browser, no server necessary! Watch Joe Cheng’s posit::conf(2023) video on Shinylive for R and see examples on the Shinylive website.

Shiny for Python entered General Availability and is ready for use in production. It comes with user guides, examples, and numerous features. Explore all the details on the Shiny blog, and read insights into “Why Shiny for Python?




The tidymodels framework is a collection of R packages for modeling and machine learning using tidyverse principles. Every quarter, the team releases a roundup of their updates. This year saw speed improvements, updated warnings, and better error messages, as well as a host of new and updated packages.  See the updates for Q1, Q2, Q3, and Q4.

  2. The second edition of R Packages has also been released! Learn how to create a package, the fundamental unit of shareable, reusable, and reproducible R code.




MLOps are a set of practices to deploy and maintain machine learning models in production. Isabel Zimmerman shares some considerations for assessing whether your team needs MLOps.

The vetiver package provides fluent tooling to version, share, deploy, and monitor a trained model in R and Python. Julia Silge shares how it now provides fluent support for deploying models to Amazon SageMaker.




Have you heard about webR? This amazing tool allows you to use R in the browser – no server needed! Users can interact and experiment with R code without switching between a web browser and an R console or dealing with copying and pasting example code. George Stagg, developer of webR, showcases the tool in several intro videos.


Other packages


2023 has too many updates to list in this blog post, but we also wanted to highlight updates to httr2, pak, and testthat.
