oh! Also in this release: 4 new tools for common #RStats package dev tasks: running tests, checking test coverage, running R CMD check and rebuilding documentation. These tools are a great way to get Claude Code and Codex to run tests 🧪 without burning tokens 🔥

Happy holidays! 🎄 I snuck in a {btw} release just before CRAN went on vacation for the year. {btw} is an #RStats package full of tools for LLMs, including a new tool for running R code. Here's a quick demo using `btw_app()` to create a quick festive ggplot2 from holiday movie titles. Cheers! 🧑🎄

For months I've had a pesky message that shows up in my #RStats test logs and today I realized I can figure out exactly where it's coming from with testthat's location reporter
Rscript -e 'devtools::test(reporter = "location")' 2>&1 | tee test.log

“Search history,” a poem (by me)
How to prepare duck breast
In the fall of democracy,
And protect overwintering bees
And immigrants.
De-icing your freezer
And town square,
And saying what you mean
To get a knee off your chest.
Six ways to make casserole
Without health insurance.

I'll be keynoting at R/Pharma a week from today! The conference is free and virtual. I'll be focused on the mundane use cases of LLMs for wrangling data with #rstats, and the content should feel applicable for folks outside of pharma—come through. :)

This morning my ChatGPT quota was inexplicably exhausted.
It took a while but I pieced it together. Voice mode somehow got activated when I went to bed.
The bot then engaged in a 10 hour conversation with my snoring dog, answering questions the pup wasn’t asking and praising him for his insight.
