testthat 3.3.0 out now! This is a massive release with tons of improvements including better failure messages, new expectations, improved snapshotting, new vignettes, and much much more: tidyverse.org/blog/2025/11... Post includes some thoughts on developing an #rstats package with Claude Code.

Python Open-Source Developer Posit is hiring a Python open-source developer to create more data analysis tools.

We're hiring an open-source #python developer focused on modeling APIs!

#numpy #scipy #scikitlearn

Well, it's official. #UNL Chancellor Bennett submitted his final proposal and it includes eliminating the #statistics department. budgetprocess.unl.edu/final-budget...

Guess it's time to go look for jobs. Anyone looking for a couple of very talented #datavis researchers?

My keynote about data science tools at posit::conf is now online! I originally meant it to be a talk about Positron, but as I was writing it, it took a left turn through the history of RStudio and into the philosophy of tool design & how to build stuff for people.

Example of using `filter_out()` on the `penguins` dataset, showing how it is much easier than `filter()`, especially with `NA`s

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

If you're following the #UNL #statistics saga (proposed for elimination based on bad stats), you might find the seminar we gave yesterday interesting... youtu.be/fUk2R0UYWpA

It was weird to rail against someone for an hour, but strangely cathartic, and the #datavis seems to have been effective?

Hopefully, today the #statistics department finds out what the acad prog cmte will recommend to the chancellor. The next step is the #nebraskaRegents. We have a letter-writing campaign to show this set of cuts is politically unpopular and will hurt the state.

Email from ChatGPT with the following text: Start with any question Chat now You don’t need a plan or the perfect question to use ChatGPT. Just start typing whatever’s on your mind — a half-baked idea, a random question, a weird "what if." ChatGPT is built for all of it. No pressure. No perfect prompts. Explore ideas, create images, write stories, and summarize files in just a simple conversation. Best, The ChatGPT Team

I just got this email from ChatGPT. Is anyone really worried that people are holding off until they have "a plan or the perfect question" to use these tools?! Or was this reaction-bait that I fell for?

Caran d'Ache is always a good idea!

Automating Repetitive Reports with Quarto, 2025 MAPOR Fall Webinar Series.

Next week! I am giving a webinar on "Automating Repetitive Reports with Quarto" as part of the 2025 MAPOR Fall Webinar Series!

Save serious time and eliminate errors by letting Quarto do the heavy lifting 🏋️

I would love to see you there 💚💛💙

These companies must be using the same crazy survey provider. What is this?!

Yeah I took a screenshot of the PDF to be able to upload it! It’s also impossible to get support from @githubeducation.bsky.social.

GitHub educator benefit application -- Apprived on May 25 and August 28 for 2 years, then asked to reverify on Sep 11 and denied, approved again September 27 and then denied three times again on the same day.

What is it @github.com @githubeducation.bsky.social? Am I faculty or am I not faculty? Why do you keep asking me the same question, after saying you won't ask for 2 years, and then not believing my answer?

Alt text: Curator Isabella Velásquez, Sr. Product Marketing Manager at Posit. Recently gave a workshop on survey analysis at the useR conference; is updating a book called Data Science in Education Using R.

This week’s #RLadies curator is @ivelasq3.bsky.social!

Do you like cleaning data? According to @rdpeng.org, it was a big part of a data scientist's job 10 years ago, and he misses it!

On the latest Test Set, Roger discusses changes in the field and what to focus on now that AI is taking over rote tasks.

Someone needs to go through last few years’ social media posts and slack messages to find all the places you foreshadowed this!

Just finished at #useR2025 and had a great time! Especially because I had an opportunity to present ggdibbler.

The slides from my talk are available here: harriet-mason.github.io/talk_useR-20... (Although they are a bit confusing out of context)

Thank you! And thanks for your work on the program committee too. Those couple of brief but productive zoom sessions helped keep things moving along real nicely!

Huge 👏👏👏 to @calpolyslo.bsky.social WunderKind @visruth.com for his #useR2025 talk on {flourish}!

🌟{flourish} is a Quarto extension for adding highlighting to source code chunks - the successor to {flair} in Rmd.

🔗 V's slides: visruth.com/flourish-talk

🔗 Github: github.com/kbodwin/flourish

@rundel.bsky.social gave us insights into using both {parsermd} (well established, tested) and {markermd} (newer and used some vibe coding) that makes extracting info the actual documents of quarto/rmarkdown files *very easy* (extremely useful for teaching/grading/checking) 🤩 check it out! #useR2025

Wrapped up #useR2025 👩‍💻

Feeling inspired to explore Positro and dive into tools like Air, chores, hexsession, arrow, and sparsvctrs.

Also made a tile of my R package collection with hexsession 📦✨.

Thanks to everyone who made this event such a great learning experience 🙌
