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

I got access to RStudio's AI enhanced beta, and oh my is it nice... Much number crunching to be had here, and way easier then copy/pasting between Claude Code/Codex and RStudio.

mirai 2.6.0 is on CRAN — R's async framework now deploys from your laptop to Posit Workbench with a single call. New HTTP launcher, C-level dispatcher with near-zero overhead, `race_mirai()` for process-as-completed patterns, and sync mode for debugging. tidyverse.org/blog/2026/02/mirai-2-6-0/

#rstats I'm very happy to announce Jarl 0.4.0! Jarl is a very fast R linter, written in Rust. This release brings lots of improvements and fixes. See the blog post: www.etiennebacher.com/posts/2026-0... And the full changelog: jarl.etiennebacher.com/changelog 🧵 to highlight some features below

dplyr 1.2.0 is out now and we are SO excited! - `filter_out()` for dropping rows - `recode_values()`, `replace_values()`, and `replace_when()` that join `case_when()` as a complete family of recoding/replacing tools These are huge quality of life wins for #rstats! tidyverse.org/blog/2026/02...

dplyr 1.2.0

dplyr 1.2.0 fills in some important gaps in dplyr's API: we've added a new complement to `filter()` focused on dropping rows, and we've expanded the `case_when()` family with three new recoding and re...

#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. Blog post: www.etiennebacher.com/posts/2025-1...

I'm honoured and delighted to be delivering the keynote for Japan.R 2025 in Tokyo on Dec 6. New ideas on creativity and community in open source software. Live demonstrations of ggbot2, OpenTelemetry and mirai (Posit ecosystem-wide initiatives). #Rstats #Tidyverse japanr.connpass.com/event/374714/

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 Read more and leave feedback here: github.com/tidyverse/ti...

I'm excited to share side::kick(), an experimental open-source coding agent for RStudio built entirely in R. It can interact with your files, communicate with your active #rstats session, and run code. Check it out: github.com/simonpcouch/...

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.

pkgload 1.4.1 is now on CRAN, with many fixes for the generation of `compile_commands.json`. If you write C/C++ code in your packages with Positron or VS Code (or any IDE with the clangd LSP), make sure to update. Thanks a lot to all contributors! #rstats

New blog post! @posit.co Positron doesn't use Rproj files tofor #rstats projects—instead you open folders in the IDE directly. Opening folders can be a little tricky though. This shortcut lets you right click on a folder in macOS Finder to open a it in Positron! www.andrewheiss.com/blog/2025/07...

Bleeding edge update for the #tidyverse purrr package with even more seamless #rstats parallel maps. Introducing our shiniest new adverb: `in_parallel()`. Just wrap your function to take advantage of blazing fast parallel processing via mirai. pak::pak("tidyverse/purrr") purrr.tidyverse.org/dev/

Mastering typefaces and fonts in #rstats has always been harder than it should. I have tried to collect much of my relevant knowledge in this deep-dive blog post so you can spend your time picking the right typeface instead of cursing at the computer

Fonts in R
