roxygen2 8.1.0 is now out with two small performance improvements: opensource.posit.co/blog/2026-08... (one will probably change your NAMESPACE, hence the minor version + blog post)

roxygen2 8.1.0

roxygen2 8.1.0 is now on CRAN. This release is mostly about performance: `@importFrom` now generates a single merged `importFrom()` directive per package, which makes your package load faster, and lin...

Quarto 1.10 shipped Friday. The highlights page lists one feature. The changelog lists 74. Mostly preview friction: stale pages, _brand.yml ignored until restart, format: changes needing two renders. If you work in Positron, that's your whole day. A boring release. Best kind.

I adore examples of good crosspolination across languages. In-line dependencies is an awesome uv feature. Excited to see it inhabit the R and Quarto worlds as well!

I'm happy to share `ir`, a new command-line tool for running portable R scripts and Quarto documents. It's inspired by my two favorite parts of `uv`: self-describing scripts and tools you can run without installing first. opensource.posit.co/blog/2026-07...

We're continuing our work on {mori} the package for shared memory in #Rstats. Debuted in April, we just released 0.2.2. A patch release for technical correctness, it's a prerequisite for future work we have planned. We hope you'll try it out as we build out more features! shikokuchuo.net/mori

Today I shipped a patch version of mirai 2.7.2 with as many changes as a full version! Lower dispatch overhead for `mirai_map()` and `everywhere()` and clearer errors + many edge case fixes. These automatically translate into wins if you use parallel purrr! mirai.r-lib.org #Rstats #Tidyverse

Always enjoy hearing Emi talk! #statistics #teaching

I've distilled my experience of useR! 2026 Warsaw into a blog post. Hoping that people who couldn't attend get a taste of it, and are motivated to participate in the next one - or come join us for posit::conf(2026) in Houston! #RStats #useR2026 opensource.posit.co/blog/2026-07...

useR! 2026: CRDTs, community, and contributing back to R

Reflections from useR! 2026 in Warsaw - talking about CRDTs and collaborative editing coming to Quarto 2, increasing adoption of mirai and mori, and a day spent contributing to base R at R Dev Day.

Until next time! It's been a fantastic #useR2026 in Warsaw. Honestly, there's a real depth to the talent we have in our #Rstats community. Keep doing your amazing work and wow us all at the next conf! (can you spot me here?)

It's always nice to re-connect with old friends, but some of my best conversations at #useR2026 this year have been with people I'm meeting for the first time. For many of them this is their first useR!, even if they've been doing #Rstats stuff for a number of years. I also spoke about CRDTs today!

Really enjoyed the talk by Charlie Gao (@shikokuchuo.net) on real-time collaborative editing at #useR2026. If this makes it into Quarto 2, I'll be very excited to try it out. 🚀

#Rstats really is a great community - I'm surprised by how many ppl I know through past events. It's been so great catching up with you all - everyone I've spoken to thus far. Also delighted to be meeting some people for the first time! #useR2026 opening reception a success, onto the first conf day!

It's summer again, and that means #useR2026 🤗 #Rstats

Installing mirai from source just got simpler: no more CMake. As of nanonext 1.10.0 (mirai's communications layer), the whole stack now builds with just a C compiler. This means mirai installs anywhere R does, even on really ancient Linux boxes! mirai.r-lib.org #Rstats #Tidyverse #RShiny
