#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 talked about GeoArrow at FOSS4G Auckland 2025! Here's my slides. GeoArrow on Web; Can We Live Without GeoJSON? yutannihilation.github.io/foss4g-2025-...

Congratulations to my student, Maggie Ma, for publishing her first #rstats package {ggincerta} on CRAN 🥳 Spatial uncertainty visualisation (bivariate, pixel, exceedance, glyph), like {Vizumap}, but fully integrated with ggplot2 -- a much simpler API with all the advantages of the ggplot2 system.

testthat 3.3.0 out now! This is a massive release with tons of improvements including better failure messages, new expectations, improved snapshotting, new vignettes, and much much more: tidyverse.org/blog/2025/11... Post includes some thoughts on developing an #rstats package with Claude Code.

Are you interested in Japan's historical map, or creating historical maps with modern web technologies general? 🗺️ If so, you should find this writeup by my colleague interesting!

This @posit.co::conf(2025) talk is everything: "The geospatial suite for Arrow is relatively new...so this is a PSA that it exists and it's really powerful and impressive. I actually also found it very easy to use...and I didn't really have much trouble learning it" www.youtube.com/watch?v=EHyg...

We recently completed the move of the #stac-geoparquet specification documents to a new repository in the @radiant.earth Github org: github.com/radiantearth... Check out the rendered HTML here: radiantearth.github.io/stac-geoparq...
