palaeoverse is a community-driven R package of generic functions to help streamline palaeobiological analyses and improve code readability and reproducibility. This is our last version before a major refactor in Autumn, supported by funding from the @softwaresaved.bsky.social.

New post on the R-hub blog! "Refactoring with Jarl: a coffee chat" ✨ By @frick.ws + myself, reviewed by @etiennebacher.bsky.social blog.r-hub.io/2026/06/02/j... #RStats

extendr v0.9.0 is release! 🚀 (hopefully) our last until v1.0.0! Improved DX 👨🏻‍💻 𝙢𝙞𝙜𝙧𝙖𝙩𝙞𝙤𝙣 𝙜𝙪𝙞𝙙𝙚 included! - `anyhow` support out of the box - deprecates `rextendr::document()` use {devtools} only! - use std trait implementations instead of custom methods #rstats #rust extendr.rs/blog/posts/2...

🚨 #RStats and #PyData devs! I'm looking for β testers for this thing I just built: A unified dashboard + orchestrator for code and data quality checks. It has lots of neat features and I'm super eager for feedback and bug reports. Check out the video demo: vincentarelbundock.github.io/scrutin/

#rstats New post: Refactoring code with `flir` `flir` is a pkg I created last year, similar to `lintr` but faster and with automatic fixes. In this post, I explain how to extend it, for instance to replace superseded and deprecated functions in large projects www.etiennebacher.com/posts/2025-0...

Polars has gotten 4x faster than Polars! 🚀 In the last months, the team has worked incredibly hard on the new-streaming engine and the results pay off. It is incredibly fast, and beats the Polars in-memory engine by a factor of 4 on a 96vCPU machine.
