#rstats I'm very happy to announce Jarl 0.4.0! Jarl is a very fast R linter, written in Rust. This release brings lots of improvements and fixes. See the blog post: www.etiennebacher.com/posts/2026-0... And the full changelog: jarl.etiennebacher.com/changelog 🧵 to highlight some features below

dplyr 1.2.0 is out now and we are SO excited! - `filter_out()` for dropping rows - `recode_values()`, `replace_values()`, and `replace_when()` that join `case_when()` as a complete family of recoding/replacing tools These are huge quality of life wins for #rstats! tidyverse.org/blog/2026/02...

#rstats Please welcome Jarl, a new R linter. Jarl is a CLI tool with extensions in VS Code, Positron, and Zed. It can check thousands of lines of R code in milliseconds. Jarl provides several output formats, a Github Actions workflow, and more. Blog post: www.etiennebacher.com/posts/2025-1...

I'm honoured and delighted to be delivering the keynote for Japan.R 2025 in Tokyo on Dec 6. New ideas on creativity and community in open source software. Live demonstrations of ggbot2, OpenTelemetry and mirai (Posit ecosystem-wide initiatives). #Rstats #Tidyverse japanr.connpass.com/event/374714/

We are looking for #rstats community feedback on 3 new dplyr functions! We're aiming to expand the `filter()` family: - `filter()` to keep rows - `filter_out()` to drop rows - `when_any()` and `when_all()` as modifiers Read more and leave feedback here: github.com/tidyverse/ti...

I'm excited to share side::kick(), an experimental open-source coding agent for RStudio built entirely in R. It can interact with your files, communicate with your active #rstats session, and run code. Check it out: github.com/simonpcouch/...

I'm excited to share a new version of the Air formatter for #rstats, with support for tabular formatting! Super useful with `tibble::tribble()` calls or `data.table::fcase()`. It's currently experimental as we're looking to get feedback on the feature, so please let us know what you think.

pkgload 1.4.1 is now on CRAN, with many fixes for the generation of `compile_commands.json`. If you write C/C++ code in your packages with Positron or VS Code (or any IDE with the clangd LSP), make sure to update. Thanks a lot to all contributors! #rstats

New blog post! @posit.co Positron doesn't use Rproj files tofor #rstats projects—instead you open folders in the IDE directly. Opening folders can be a little tricky though. This shortcut lets you right click on a folder in macOS Finder to open a it in Positron! www.andrewheiss.com/blog/2025/07...

Bleeding edge update for the #tidyverse purrr package with even more seamless #rstats parallel maps. Introducing our shiniest new adverb: `in_parallel()`. Just wrap your function to take advantage of blazing fast parallel processing via mirai. pak::pak("tidyverse/purrr") purrr.tidyverse.org/dev/

Positron now supports a chat panel with Claude and it's pretty neat

At Posit, we love @typst.app: ⚡ Make PDFs in milliseconds, not minutes ✨ The power of LaTeX with today's technologies ✍️ Modern typography (including emojis!) 🧠 Clear mental model So I'm thrilled to announce that we're now supporting its development: posit.co/blog/posit-a... #rstats

Mastering typefaces and fonts in #rstats has always been harder than it should. I have tried to collect much of my relevant knowledge in this deep-dive blog post so you can spend your time picking the right typeface instead of cursing at the computer

For the last couple of months I've been working on something and I'm excited to finally share an early preview: Say hello to plumber2 🎉 plumber2 is a full rewrite of the plumber package for creating powerful webapis in #rstats. It takes everything we have learned from plumber and adds even more

We're delighted to announce Jonathan McPherson – software architect at Posit – as keynote speaker at posit::conf(2025)! If you're curious about how thoughtful design principles can improve the data science tools you use, you won't want to miss this! Join us Sep 16-18 in Atlanta. pos.it/conf

I want to highlight that v0.1.1 of {ellmer} has been on CRAN for a few weeks now. This version includes a ton of improvements when using an LLM hosted on Azure, AWS, Databricks, or Snowflake from #rstats -- which is pretty common in enterprise settings. 🧵 ellmer.tidyverse.org/news/index.h...

@lionelhenry.bsky.social and I are so excited to finally announce Air - an extremely fast R code formatter! 🎉 With Air, you'll never need to worry about styling your #rstats code ever again. All you need to do is save, and Air takes care of the rest. www.tidyverse.org/blog/2025/02...

Which of these features would you like us to implement first in the nanoparquet R package? See options below. #RStats #parquet nanoparquet.r-lib.org

Parallelization just landed in the dev version of purrr: purrr.tidyverse.org/dev/referenc... Really pleased that the mirai framework makes this possible. Huge credit to the tidyverse maintainers @hadley.nz @lionelhenry.bsky.social and @davisvaughan.bsky.social ! #rstats #tidyverse

We're delighted to announce Cat Hicks @grimalkina.bsky.social – psychologist for software teams – will be a keynote speaker at posit::conf(2025)! Discover psychology tips for better dev teams and much more at conf. Register at pos.it/conf #PositConf2025 #DataScience #OpenSource #Python #RStats

Introducing ensure, a new #rstats package for LLM-assisted unit testing in RStudio! Select some code, press a shortcut, and then the helper will stream testing code into the corresponding test file that incorporates context from your project. github.com/simonpcouch/...

We are thrilled to announce that we have a new @posit.co Starter Pack, thanks to @jeremy-data.bsky.social! Find and follow Posit people here: go.bsky.app/RxAPkGi

I've written a series of blog posts about what I've been up to over the last few months! 📝 In the posts I talk about webR, R Shinylive, and a new Quarto extension for interactive code exercises. Take a look if you're interested in the latest for R for WebAssembly. www.tidyverse.org/blog/2024/10...

S7 0.2.0 is now on CRAN, thanks primarily to the hard work of @t-kalinowski.bsky.social. S7 is a collaborative effort to supersede S3 and S4 and you can read all about it (and what's new in 0.2.0) at www.tidyverse.org/blog/2024/11... #rstats

The video for my #PositConf2024 talk about evaluating censored regression #rstats models is at: youtu.be/cm34R5aYUQ4?... Here is a list for all of the talks: posit.co/blog/talks-a...

Our #PositConf2024 talk(s) on Positron are now available on YouTube! It was really special to get to introduce this new project to folks ❤️ and I'm excited this is broadly available now. Take a look if you are curious about our new IDE: youtu.be/8uRcB34Hhsw
