New Post on @ropensci.org: Better #RStats Code, Without Any Effort, Without Even AI Edited by @etiennebacher.bsky.social & Steffi LaZerte Read about: ✨ {lintr} for detecting lints ✨ Air for formatting code ✨ jarl for detecting+fixing lints ✨ {flir} for refactoring ropensci.org/blog/2025/12...

Today I'm talking about contributing to base R 💻 Are you curious about how to improve the language we love, at its core? This is a thread for you! #RStats

I got to hear a sneak peek of Stephanie’s keynote, and it was so good! Definitely recommend watching if you work on teams adopting or transitioning to #RStats.

Are you a data human who has always been a little intimidated by #AdventofCode? Come to the #DataScienceLab on Dec 2nd where @emilhvitfeldt.bsky.social will give us a super friendly hands-on intro. Very casual, lurk friendly. Register for the event series @ pos.it/dslab #databs #rstats #pydata

All models are wrong; some are useful. All LLM outputs are hallucinations. Some are useful.

Merry December folks! Wanna know your most used and co-dependent geoms this past year?! I've built "Spotify Wrapped" for {ggplot2} that produces you an interactive story and analytical tools for your geom usage! #rstats Build your own report by following the docs: gpcds.com/ggplot2wrapp...

I spent a bit of time this weekend updating my #Quarto listing for talks and workshops 🤗 Check it out here: ivelasq.rbind.io/talk Many thanks to Meghan Hall for sharing the template and CSS code! 💜

I'm reminded of how handy the usethis::browse_*() functions are and thought I'd remind people they exist. Choose from a menu of links or go straight to CRAN or GitHub. #rstats

I don't know how I missed this, but the blog post on ggplot2 extensions was an R Weekly highlight last week! Thank you so much to R Weekly and the curators! 💜 Here is the post if you would like to see it: rworks.dev/posts/ggplot...

Woo, the post is on Data Elixir! It's a really great data science newsletter if you are looking for one! dataelixir.com

I had a great time presenting at the 2025 MAPOR Fall Webinar Series on "Automating Repetitive Reports with Quarto" and #RStats! Recording is available on the MAPOR website, and here are the slides if you are interested! 🧡💗 📝 Slides: ivelasq-automating-quarto.share.connect.posit.cloud#/title-slide

Do you teach #rstats? Do your students complain about how lame and old-fashioned dplyr is? Don't worry: I have the solution for you: github.com/hadley/genzp.... genzplyr is dplyr, but bussin fr fr no cap.

🚀 New blog post: "Lua Best Practices for Quarto Extensions" Transform your working code into maintainable, robust extensions with proven patterns: - Modular architecture - Parameter scoping Level up your Quarto game! mickael.canouil.fr/posts/2025-1... #Quarto #QuartoPub #Lua #DataScience

My election night R code worked last night! 🎉! Inspired by @andrew.heiss.phd & @gosterhout.bsky.social 's #PositConf2025 talk re Idaho's website built with R, Quarto & the {targets} #RStats 📦 My results page: www.district2framingham.com/posts/2025-1... Their repo: github.com/andrewheiss/... 1/2

I wrote a lil post on the amazing work that @ginareynolds.bsky.social does championing ggplot2 extension developers and teaching others to build their own! The post features the Scrollytelling Quarto extension and the group's cute #RStats hex 🐱: rworks.dev/posts/ggplot...

I'm looking forward to this talk! Thanks for the invite for this great conference

I'm super excited to give a workshop during next week's R/Pharma conference! Join me if you'd like to discuss the ✨beautiful✨ outputs you can create with #Quarto and #RStats. 📅 Tuesday, November 4 at 9 am CT 🔗 Free to register, too! events.zoom.us/ev/Ai-geyS63...

Happy logical Halloween

I loved discussing "Positron for RStudio Users: A Gentle Introduction" with @simisani.bsky.social & R-Ladies Gaborone! Check out the recording and materials: 📹 www.youtube.com/watch?v=2fOQ... 📝 ivelasq.rbind.io/talk/positro... I hope this intro is better than the one between my three cats 😹

Looks like the Revolutions Analytics blog is down 😔 Used to be on my regular bookmarks rotation in the early 2010's. End of an #RStats era. blog.revolutionanalytics.com

There is a new monthly release of #Positron available, and it delivers fresh new features for the Data Explorer! In this screencast, I walk through how to interactively explore a recent #TidyTuesday dataset on literary prizes 📚📖🏆 using some of the Data Explorer newness. youtu.be/KOgQuWF0US4

Quarto has a way to collapse code, but what if you want to collapse code OUTPUT? The amazing @mickael.canouil.fr created an extension that does just that!!! Check it out! github.com/mcanouil/qua...

Love reading Posit's AI Newsletter as a nice, quick way of getting AI news without feeling overwhelmed. Today's edition is now out!! 😄 posit.co/blog/2025-10...

New blog post on the right and wrong way to rake a survey's data to estimates from another survey. As an example, it shows what can go wrong when we rake data from a poll to benchmark data from Pew's National Public Opinion Reference Survey. www.practicalsignificance.com/posts/npors-...

Super excited to share what I've learned picking up Positron as a long-time RStudio user! 💙

I’m so excited to be your curator this week! Be sure to follow @weare.rladies.org and see you on Monday 😎

ellmer (for #RStats) and chatlas (for #Python) integrate LLMs directly into your code. They also support local LLMs (like #Ollama) so you can run models on your own machine, in case you have sensitive data, a lack of API access, or cost restrictions. Check out how here! posit.co/blog/setting...

Hello there, #rstats, I know y'all are enjoying the last weeks of summer and I am just reminding you that the deadline for submissions for the @rconsortium.bsky.social #R+AI conference is September 5th. Please take a moment and share your proposal with us! rconsortium.github.io/RplusAI_webs...

Glad to see my little site is of help 😊 you can see it here: ivelasq-posit-ai-tools.share.connect.posit.cloud Thanks for the shoutout, @rfortherestofus.com!

I originally made this Streamlit app two years ago in VS Code. Obvs a bit biased, but working with Streamlit was way easier with the preview window and Positron Assistant. Would love to know what you think 💕
