webRios is live. #rstats on your iPhone and iPad.

I showed native R compilation on #iOS last week. Shipping it is another story (thanks, GPL). This version uses #webR 's #WebAssembly build instead. Different tradeoffs, but this one clears App Review.

Promotional image for webRios showing the app icon and an iPhone displaying the R console. The console shows example R commands with syntax highlighting: basic arithmetic (1 + 1), a print statement saying 'Hello from iOS!', a warning message in orange reading 'Uh-oh, I'm in the Apple-verse?', an error message in red with the HAL 9000 quote 'I'm sorry, Dave. I'm afraid I can't do that.', and a plot command.

Ever wonder how R is actually governed?
At #useR2026, R Core veteran Peter Dalgaard traces the project’s evolution—from its 90s roots to the modern roles of CRAN and the R Foundation. A must-watch on the future of #rstats sustainability. @pdalgd.bsky.social

Do you teach #rstats? Do your students complain about how lame and old-fashioned dplyr is? Don't worry: I have the solution for you: github.com/hadley/genzp....

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...

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.

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")
