Josef Fruehwald (@jofrhwld.bsky.social; 14/2/0; 2026-09-04): just re-found my notes for an R study group from 2010. Except for the landing page, it was all handwritten html, since this pre-dated knitr and rmarkdown. The tables of contents etc? I just wrote those by hand… probably in TextEdit ↪

Frank Harrell (@f2harrell.bsky.social; 10/2/0; 2026-08-31): Now I starting a new book using Typst. I’ve gotten all the advanced LaTeX features used in my earlier book translated to Typst setup + functions thanks to Claude. This includes marginal notes, back references, advanced indexing, and messy LaTeX tables. #RStats Sweave/knitr inserts R output. ↪

tj mahr 🤘 (@tjmahr.com; 6/3/0; 2026-09-04): i don’t think i’m going to mess with quarto in my blog or my analysis notebooks until that q2 thing comes out. i like controlling the build process with targets and not having to think about projects files or a command line app. my blog is just knitr+targets -> jekyll. but i am a dinosaur ↪

tj mahr 🤘 (@tjmahr.com; 2/0/0; 2026-09-03): making my knitr hook for running downlit also include the original markdown output in an html comment so that the .md file is still legible. surely, nothing bad will happen from this hacker ↪

tj mahr 🤘 (@tjmahr.com; 0/1/0; 2026-09-04): i don’t think there is going to be a new markdown flavor, based on what copilot read in the q2/claude-notes/ folder. do you know about knitr::convert_chunk_header() btw? ↪

OMG! I found a great new product in the households section of my supermarket: Certainty Wipes.

Clearly off-label, but they seem to work on my scatterplots to remove those pesky points that get in the way of saying: r = 0.70, p < .001 ↪

Tyler Morgan-Wall (@tylermw.com; 26/2/5; 2026-08-26): Ever wonder “how big is the volcano dataset in #RStats, really?”

No? Oh.

… Well, no need to (not) wonder any longer, thanks to rayshader’s upcoming raypeople with render_people() + render_trails() here!

Marc Kissel (@marckissel.bsky.social; 25/3/4; 2026-08-25): Im Teaching a data science for anthropology class using #rstats. Most never coded before/worked w/ command line interface so I live demoed using one via playing Zork, the text adventure game. They were amused how excited I got when I found the sword :). Plus fun way to intro a CLI environment. ↪

Robin Blythe (@rbly.bsky.social; 14/2/0; 2026-08-29): Often having collaborators claim you can’t use continuous predictors where there are small sample sizes for individual values of that predictor. Where does this come from? It’s incomprehensible to me. That’s the entire point of a parametric model! I’m so confused #statsky #rstats ↪
