Another example of how useful {geomtextpath} can be, imho. This is from the item category probability plot in my {easyRasch2} package. Most psychometric papers within the factor analytic tradition seem to disregard evaluating how the response scale works, which I find difficult to understand.

A coding agent is only useful if it can run whatever code the task demands, but a tool that runs arbitrary code is just as dangerous as it sounds! So how do you stop an agent from making mistakes you can't easily undo? Read more at: tidydesign.substack.com/p/help-my-co...

We're excited to announce a new release of SedonaDB, and this one is a big one! Between native DataFrame APIs in Python and R, a brand new Geography implementation, GPU accelerated joins, and a raster/ND-array foundation, it's hard to know where to start.

Air 0.10.0 is out now! - Enforce `<-` or `=` throughout your #rstats code (only one of these is correct though 😉) - Tighter Positron and RStudio integration - pre-commit / prek support - stdin support - Install with uv, mise, or pixi Read all about it! opensource.posit.co/blog/2026-06...

I've gone this far without learning what sunk-cost fallacy is, so I'm not starting now.

If you create slides in #Quarto, or WANT to, you should really attend @emilhvitfeldt.bsky.social's upcoming 2-hour slidecrafting workshop. I don't think anyone in the data world has created more reavealjs-friendly slide stuff lately than Emil. ABSOLUTELY DO IT. #rstats #databs pos.it/slide-wrkshp

I LOVE this from @jasminedaly.bsky.social 's presentation at the Salt Lake City R User Group! I think it applies to all developers in the age of AI, not only consultants and those who use R.

Wouldn't it be nice to have other data practitioners at work to chat with? People you could get comfortable pair-coding with, asking questions to, and sharing what you're working on with? A data community of practice could be like a R or PyData user group internally, or a weekly hangout, or channel

Do you love maps? Of course you do! With the latest release of #ggsql we now support spatial plotting directly from your database. As a cherry on top, the release also provides powerful in-layer aggregation. Read all about it on the blog

Coding agents like Claude Code feel like magic but they’re really a bunch of tools in a trenchcoat. This week I build a working coding agent in R, starting from just three tools. I’ll add some extra tools to make it safer and more efficient. tidydesign.substack.com/p/a-coding-a...

dbplyr 2.6.0 is here! This release leaned on Claude Code to clear a TON of smaller issues, freeing up time for the big stuff: brand-new ADBC and JDBC backends, new translations, and a new sql_dialect() to cleanly decouple connection from SQL dialect. Read more: opensource.posit.co/blog/2026-06...

I'm thrilled to share that #querychat now supports more exploratory visualization powered by #ggsql. We're excited about what this direction can unlock for data scientists looking to curate "tidy" data for others explore. Expect more on this in the coming months. opensource.posit.co/blog/2026-06...

A massive congrats to R Core for this great honour. R has been the foundation of my career and it wouldn’t have been possible without years of work from them.

I'm excited to announce a long overdue update to {tidyclust}! This release brings support for 3 new model types: DBSCAN, Gaussian mixture, and mean shift models. We also now support parallel processing with {future} and {mirai} opensource.posit.co/blog/2026-06... #rstats #tidymodels #dataBS

Coding agents like Claude Code are great at general-purpose work. Posit Assistant is built specifically for data: #RStats / #Python session access, plots in the chat, and specialized data analysis capabilities. Post + video: opensource.posit.co/blog/2026-06...

Ask a bare LLM to multiply two big numbers and it'll confidently get it wrong. But ask an LLM on the web and it gets it right. What's the difference? In my latest post, I dig further into the harness, what it can do and why it matters: open.substack.com/pub/tidydesi...

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.

Thrilled to share that @minecr.bsky.social and my paper on Ten simple rules for teaching data science is now available from @plos.org Computational Biology! journals.plos.org/ploscompbiol...

#Rstats package update: zip 3.0.0 with some very cool new things: password protected zip files, vectorized and concurrent unzip(), unzip over HTTP, progress bars. Full change log at github.com/r-lib/zip/re...

This makes me SO HAPPY! This is what I want people to do! See tidytuesdayR on CRAN for relatively easy dataset submissions! dslc-io.github.io/tidytuesdayR...

Mike Bostock's first data viz library ran on three 1x1 pixel GIFs and raw HTML tables. It kind of made a bar chart. He went on to build D3. Listen now on Spotify (open.spotify.com/episode/01BJ...) and Apple Podcasts (podcasts.apple.com/us/podcast/t...).

Panache v2.52.0 is out! 🚀 A formatter, linter & language server for Quarto, Pandoc & Markdown. New: experimental math formatter (align + whitespace normalization) and hand-written YAML parser & formatter, fully lossless, even hashpipe YAML (Quaro chunk options) https://panache.bz

When I was at PyCon US, there was so! much! buzz! around @pola.rs. For those of us who work primarily in the latter part of the data science lifecycle (reporting, etc.), I wrote a little blog post on four #Python libraries with Polars support. Check it out here! opensource.posit.co/blog/2026-06...

We've been working to make mori better - 0.2.1 is now on CRAN! Share R objects across processes with zero copies using shared memory + ALTREP. Supports mirai and all parallel frameworks. New: `prune_shared()` cleans orphaned regions, cleaner errors. github.com/shikokuchuo/... #Rstats #Tidyverse

I'm alive *AND* I wrote a blog post?! Unheard of! Much 💖 to @abbycabs.dev, and @grafana.bsky.social's David Allen and Amanda Wagner whose FOSDEM talk's were a huge source of inspo!

I've just tried Posit Assistant on the free plan and must say, I'm impressed. Using the super-cheap Gemma 4 26B model (10% cost of Sonnet) on free plan it worked instantly. Hats of to the #posit team for integrating this into RStudio and allowing people to test with free plan!

#RStats challenge and potential community project: * Create a minimal package 'dumpsterfire' that triggers as many 'R CMD check' issues as possible! Fun, but could also become a excellent resource for illustrating and understanding package check issues Here's a start: github.com/HenrikBengts...

This week on my substack: what is an agent open.substack.com/pub/tidydesi....

Geegee Plottoo is my favorite Star Wars character.

A development milestone that I'm proud to share is that we've now generated over 200 research disclosure reports for individuals with Down syndrome and their families! Each report is automatically generated through an R package (with Quarto) I've been developing over the past few years. #RStats
