Every once in a while I need to fiddle with long category labels in #rstats ggplot2.
It always helps me to refer back to this excellent blog post by #AndrewHeiss @cararthompson.bsky.social

Weird ggplot thing that got me this week with the update to 4.0 - it supports new ink and paper arguments (www.tidyverse.org/blog/2025/09... ) and they've changed how transparency works! If you a transparent bg, you can control it with theme_*() now #rstats

library(ggplot2)

# Doesn't work anymore!
ggplot(data = mtcars, aes(x = hp, y = mpg)) +
geom_point() +
theme_minimal()
ggsave("not-transparent.png", bg = "transparent")

# This works!
ggplot(data = mtcars, aes(x = hp, y = mpg)) +
geom_point() +
theme_minimal(paper = "transparent")
ggsave("yes-transparent.png")

I'm exited to announce a new resource about making slides with quarto and revealjs. This book is the combination of all the work I have done in this area, reordered and polished up

There isn't a lot of new information yet, but this format allows me to add more easily

{hexsession} by @liomys.mx is fun and useful!

Produces css/html snippets that tile hex logos nicely, e.g. to showcase your #rstats package projects. 😎

OK #PositConf2025 -- I acquired most of the stickers I heard were available; here's my final score! (Thanks for the assists @ivelasq3.bsky.social ({dtplyr}!!!) @kellybodwin.com and @emilhvitfeldt.bsky.social ). I'll be re-distributing many of these to my students as leaderboard prizes 👩‍🎓👨‍🎓 #rstats

A rendered html/pdf of a qmd is so much easier to read and follow compared to reading a qmd in a text editor with code chunks and all sorts of additional markup.

Why do we 💙 #ggplot2?

Yes, it's for the Grammar!

But also for the passionate and supportive community — and their steady contributions to the ggplot2 universe: all the extension packages 🧩 that take its impressive flexibility even further, making it more powerful and beautiful 🙌

maize
{maize} 🌽 is an extension library for kernels & support vector machines in tidymodels! The package consists of additional kernel bindings that are not available in the {parsnip} or {recipes} package. Many of the kernels are ported from {kernlab}, additional kernels have been added directly to maize transposed from Python and Julia packages.

{parnsip} has three kernels available: linear, radial basis function, & polynomial. {maize} extends to further kernels, other engines, and adds steps for {recipes}:
