#rstats #quarto - has anyone written anything on how Quarto meets (or fails to meet) modern web accessibility standards? Had a query from our digital team. I imagine some of it would be up to the user - e.g., add alt text - so my second question is there a guide "writing an accessible quarto doc?"

#rstats #dplyr wizards - I come cap in hand in a time of need - github.com/tidyverse/dp... - something that seems like it should be quite simple but I can't work out how to achieve!
Recommended way to split data by a variable, apply a function, and return a bound dataframe (i.e., a non-experimental `do()` replacement) · Issue #7666 · tidyverse/dplyr
Hi folks, My question hinges on this sort of situation. Obviously this example is pretty artificial, but its a situation in which you have a function which acts on a dataframe, returns a dataframe,...

Parallelisation built-in to #rstats #purrr 📦 is a total gamechanger. I've had a play this morning and it seems to "just work" effortlessly. When this lands on CRAN we'll be able to simplify so many of our packages/workflows!
Parallelization just landed in the dev version of purrr: purrr.tidyverse.org/dev/referenc...
Really pleased that the mirai framework makes this possible.
Huge credit to the tidyverse maintainers @hadley.nz @lionelhenry.bsky.social and @davisvaughan.bsky.social !

Parallelization in purrr — parallelization
purrr's map functions have a .parallel argument to parallelize a map using
the mirai package. This allows you to run computations in parallel
using more cores on your machine, or distributed over the ...

Clever #rstats #testthat people - I'm trying to write unit tests to run on GitHub Actions but seemingly any that create a plot (e.g., ggplot2) fail on MacOS, and only MacOS. Can anyone who knows more about this than me advise what could be going on? (github.com/davidcarslaw...)

I've been trying to learn @observablehq.com #framework through #tidytuesday. I've lagged behind a few weeks, and never posted about it on Bluesky, so here's what I've done so far! The dashboards are found at jack-davison.github.io/TidyTuesdayO..., code at github.com/jack-davison... 🧵

Just released v 0.9.1 of our #rstats 📦 {openairmaps}, which combines #openair with #leaflet for dynamic #airquality mapping. Lots of fixes, but main feature is allowing for "pairwise" stats in `polarMap()`. Read more about pairwise bivariate polar surfaces: bookdown.org/david_carsla...

I wrote something #rstats a few months ago and never really plugged it. I love #leaflet, but awesomeMarkers is v limited - instead `leaf.magic::magicIcons` uses {magick} to construct icons on the fly. Totally customisable sizes/icons/colours/shapes. See more at: github.com/jack-davison...
