Self-cleaning test fixtures A wild romp through environments -- namely, the environments associated with functions and tests. How to adopt a low-impact lifestyle.

this is one of my very favorite things about withr's take on this

withr::defer() -> withr::deferred_run()

A close-up view of a computer monitor in a dimly lit room, showing a terminal console. The terminal displays the output of an R function called meetupr_sitrep(). The report shows green checkmarks for "Active Authentication" and "Cached Token," and a blue information icon for package settings. At the bottom, a red "X" marks a failed "API Connectivity Test," illustrating a diagnostic situation report in action. In the foreground, a coffee mug and a person’s hand on a keyboard are visible but slightly out of focus.

Stop playing "diagnostics ping-pong" with your users 🏓

Wrote about why every R package wrapping external tools needs a sitrep() function — with real examples from meetupr and freesurfer.

Good news: The posit::conf(2026) Call for Talks has been extended to Friday, February 20!
Join us in Houston to share your work with the R & Python community.
🎤 Speakers receive: Professional coaching, free conference pass, travel assistance
Submit your 20-min talk proposal: pos.it/conf-talk-2026

you don't need to copy/paste from that preview! the rendered reprex, in a friendly md form, is already on your clipboard 😆

the htmlpreview is for your 👀, but the good stuff is on the clipboard waiting to be pasted in the relevant venue (default is github, but slack can also be requested)

Speak at posit::conf(2026) and share your R & Python stories!

Accepted speakers get:
✨ Travel & lodging help
✨ Free conference pass
✨ Professional coaching

Apply by Feb 6 to join us Sept 14-16 in Houston, TX!

the tidyr::separate_wider_*() functions might offer a nice little improvement to your existing approach

this idea has been kicking around for years and @henrikbengtsson.bsky.social catalyzed something at an rOpenSci unconf once: github.com/HenrikBengts...

Vignette workflows are just inherently awkward since, unlike help topics and `man/*.Rd` files, the rendered form of vignettes has no legit business or home inside an R package in source form. This chapter outlines some of the least bad workflows:

r-pkgs.org/vignettes.html

I define short aliases `bp()` and `bg()` for `usethis::browse_package()` and `usethis::browse_github()` in `.Rprofile` because I use them so much.

Screenshot showing usage of usethis::browse_package(), usethis::browse_cran(), and usethis::browse_github().

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

This gives a fantastic framing of how to think about reproducibility (it's a spectrum) and how to use renv with intention. Highly recommend, even if you're not using renv, to get a better understanding of how to live in peace as R and package versions advance 🕊️ #rstats

YouTube video by Posit PBC 10 Years of Data Science Tools...and What Happens Next (Jonathan McPherson) | posit::conf(2025)

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

Read more and leave feedback here:
github.com/tidyverse/ti...

maybe it should be your first Pythong package 🩴

Will definitely include this example in my next talk on how to name files!

✅ Full marks for "make it easy to guess what the heck something is, based on it name".

I loved discussing "Positron for RStudio Users: A Gentle Introduction" with @simisani.bsky.social & R-Ladies Gaborone!

I hope this intro is better than the one between my three cats 😹

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.

I still marvel at the choice to do "C:\Program Files"

bliki: Frequency Reduces Difficulty "If it hurts - do it more often". Good advice if the amount of pain raises exponentially with the time between actions, such as for integrating software.

BTW this "Frequency Reduces Difficulty" post from @martinfowler.com is the origin of the mantra "if it hurts, do it more often" (at least, it's where I learned it). It's amazing how broadly this applies.

I bet the whole reason he's thinking about this is that I was complaining to him (to everyone, really) about the pain of using Windows full-time while my macbook's logic board gets replaced. And he brought out the house words "if it hurts, do it more often!"

this is a *wild* exaggeration but I'll allow it 🤣

2️⃣ I HAVE SUCH STRONG FEELINGS ABOUT THIS but already sense that it's a lost cause

GitHub - r-lib/rig: The R Installation Manager The R Installation Manager. Contribute to r-lib/rig development by creating an account on GitHub.

I'd install Xcode command line tools (NOT all of Xcode) to get git and compilers, etc. (xcode-select --install)

and I'd use rig to install one or more versions of R (github.com/r-lib/rig)

(my macbook's logic board failed and is being replaced, so I'll be doing all this set up myself soon 😬)

you should be using pak

Ever run `install.packages()` and wish it were faster, smarter, and more reliable?

The {pak} package speeds things up with parallel downloads, dependency solving, and reproducible installs.

Air is our incredibly fast R code formatter!

Come learn all about it at 2:40pm in Regency V in the Sparking Development Joy session!!

We also have hex stickers!

The equivalent of the Bechdel test for a tech-ish event is “is there a line for the womens bathroom?” and #positconf just passed with flying colours 😅
