dude, this is sick!!!!! #rstats

On each package page, the call graph is tinted by test coverage: functions green where tests reach them, red where they don't. That needs the package to have tests. covr measures your own coverage; here you can see it for other packages too. r-observatory.thecoatlessprofessor.com/packages/Rcp...

The Rcpp call graph on R Observatory. An interactive network plots the package's 411 functions as nodes tinted by test coverage on a red-to-green scale, with node shape marking language and rings marking exported functions; edges show calls, including dashed edges from R into compiled code. A side panel shows per-function detail on hover, here the exported sourceCpp function with its line count, cyclomatic complexity, 100% line coverage, and call list. Below the graph, summaries break coverage down by type and by file, tally the structure (411 functions, 18 exported, 291 compiled, 497 call edges), and rank functions by lowest coverage.

The download number everyone cites is a single CRAN mirror. R Observatory also counts conda-forge, Bioconductor, bioconda, r2u, & more, so you see much more of where a package actually gets installed. Still not every source, but well past one mirror. r-observatory.thecoatlessprofessor.com/downloads

The Downloads overview on R Observatory, titled "Package download activity across every data source we track." A row of source filters includes CRAN, r2u, Bioconductor, autoCRAN, conda-forge, bioconda, and c2d4u, with Posit P3M and Fedora COPR marked "soon." A headline reads 277.1M downloads in the last 30 days, combined across 7 active sources, broken down by a stacked bar (CRAN 84.7%, conda-forge 10.3%, Bioconductor 2.7%, and smaller shares from the rest). An ecosystem-trend chart runs from 2012 to 2026, and a "Top packages, combined" table lists the most-downloaded packages with per-source columns.

Am i crazy or should `scale_viridis_d()` work with integers because they're discrete values? #rstats

Error in `scale_fill_viridis_d()` at 2026-06-22/R/dev-block-grid.R:21:1:
! Continuous value supplied to a discrete scale.

The Cascadia R Conference this year was a success! The best part of the conference, and R programming in general, is the community 🌈 ®️💙. See you next year in Seattle, WA! #CascadiaRConf #rlang #rstats #DataScience #community #coding

Dewey Dunnington @paleolimbot.bsky.social · last mo.

...and, of course, we didn't leave out #rstats. The 0.4.0 release features the sdplyr R package, which provides a dplyr interface covering the basic subset of transformations (including spatial joins!). Like Python, our ST_ and RS_ functions have inline docs via the generated sedonafns package.

See you tomorrowww!!!!!!

🎉 The Cascadia R Conference starts TOMORROW with multiple workshops on topics including Shiny, GIS, GitHub, Quarto, and Rust! We're excited to welcome everyone for a couple of fun days of learning R and networking in beautiful Portland, OR. #rstats #DataScience #R #CascadiaRConf #Workshop #Coding

Beyond excited to share that catboost now has full native support in tidymodels!! This support should extend to all applicable areas of tidymodels, which means that orbital works as well 🚀 opensource.posit.co/blog/2026-06... #rstats #tidymodels

CatBoost support in tidymodels

CatBoost is now available as a supported engine in tidymodels. This post shows how to train, tune, and use CatBoost models through the familiar parsnip interface.

Don't worry, "I have the full picture now."

Not sure about contiguous blocks, mlr3spatiotemporal is another package that does spatial (and spatio-temporal) cv, mlr3spatiotempcv.mlr-org.com.

Only 2 weeks remaining before our #rstats useR 2026 blockr workshop 😱 blockr is an open source no-code data workflow builder for R built in collaboration with @bristolmyerssquibb.bsky.social 📆 When: Monday July 6 from 1pm to 4:30pm CEST 👉 blockr.site 🎮 blockr.cloud lnkd.in/e8yEmhU7

Hey #rspatial, any 📦s that perform spatial CV well? Blocked by a few {spatialsample} bugs and {blockCV} doesn't make contiguous blocks. I have a grid and want to make a contiguous holdout set. #rstats

@scalingdevtools.bsky.social any plans of episodes that aren’t centered around “AI” in the pipeline? i miss listening to this podcast 😭

semi-colons are the new em-dash

Espresso in Seattle is $2.22 - $2.72 more expensive than in Central London, btw.

Ordering a cortado in London is a toss-up between getting a flat white or a cortado. I’ve not figured out the tell

I don’t like what Claude has done to PRs
