Merry December folks!
Wanna know your most used and co-dependent geoms this past year?!
I've built "Spotify Wrapped" for {ggplot2} that produces you an interactive story and analytical tools for your geom usage! #rstats

testthat 3.3.0 is here! Major updates for #RStats testing include failure messages for easier debugging, 6 new specific expectations, and the SlowReporter to find your bottlenecks.
Heads Up: R 4.1+ is now required, and old mocking functions are removed.

#rstats Please welcome Jarl, a new R linter.
Jarl is a CLI tool with extensions in VS Code, Positron, and Zed. It can check thousands of lines of R code in milliseconds.
Jarl provides several output formats, a Github Actions workflow, and more.

If you, like me, can't remember all the Sass variables when creating #quarto #revealjs slides. I found a semi hacky way to help myself here.
Using code snippets in VS Code & Positron allow us to get pretty good completion in our style sheets

We are looking for #rstats community feedback on 3 new dplyr functions!
We're aiming to expand the `filter()` family:
- `filter()` to keep rows
- `filter_out()` to drop rows
- `when_any()` and `when_all()` as modifiers

As I have been writing slides with quarto and reveal.js I found myself writing similar styling code. I have finally gotten myself together and extracted some of those classes out into an Quarto extension. Heavily inspired by tailwindcss

I'm excited to share a new version of the Air formatter for #rstats, with support for tabular formatting! Super useful with `tibble::tribble()` calls or `data.table::fcase()`.
It's currently experimental as we're looking to get feedback on the feature, so please let us know what you think.
