The detectCores() apocalypse is creeping up on us 👻🐛

As more people are getting access to 128+ CPU cores, code spinning up parallel cluster with detectCores() workers fails - not enough #RStats connections available

Friends, do *not* default to detectCores(), bc www.jottr.org/2022/12/05/a...

Please Avoid detectCores() in your R Packages

The detectCores() function of the parallel package is probably one of the most used functions when it comes to setting the number of parallel workers to use in R. In this blog post, I’ll try to explai...

Many of us have been saying this for years noting it's extreme unprofitability. Now Bloomberg noticed

Trying out the {marquee} #rstats package for markdown-based formatting of ggplot elements and it's super neat marquee.r-lib.org

Plot showing the percent decrease in the number of polling places in a handful of US states after the 2013 Shelby County v. Holder SCOTUS ruling, with Arizona seeing a 22% decrease in voting locations. The title and subtitle use nicer typography and have keywords colored in reddish pink to match the plot

Just discovered the {loon.ggplot} 📦, designed to turn ggplot graphics into interactive (loon) plots.
It provides operations for an _interactive grammar of graphics_ -zooming, panning, and linking among any number of displays.

Provides a bridge between the 'loon' and 'ggplot2' packages. Extends the grammar of ggplot to add clauses to create interactive 'loon' plots. Existing ggplot(s) can be turned into interactive 'loon'...

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
