Line chart of the number of sheep per hectare of farmland in New Zealand between 1935 and 2025. There are peaks in late 60s and 80s but has been decreasing since, back to WWII levels. Annotations highlight WWII, and relevant animal welfare law changes in 1960, 1999, 2003, and 2022.

For this week's #TidyTuesday data about agriculture in New Zealand I wanted to see what I could do with a "simple" chart to show that you don't always need all the bells and whistles for #DataViz to be effective 📊

Fifty Releases of Pointblank: a Year of Building Data Quality Tooling - Posit The Pointblank Python library's journey has resulted in a premier, data-agnostic toolkit for tabular data validation.

Most data bugs aren't algorithm failures, they're assumption violations upstream. Pointblank makes validation a first-class citizen in R/Python workflows instead of an afterthought scattered in assert statements.

It’s pretty close but there are few upcoming features (for the next release of gt) that I really want to get into the book!

All of these are amazing! The last one especially is just w(°o°)w!

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...

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!

The pointblank R package, now at 1000 stars.

I did a workshop today on the pointblank package for R (this workshop: r-consortium.org/webinars/how...) and I thought it was great! Lots of great questions asked, and I did enjoy answering them. ALSO: the package is up to 1000 stars! Really glad to see people liking it :)

Hey! Thanks for attending (it was fun). The talk I was referring (probably very badly) was this: www.youtube.com/watch?v=N9ka...
It's an excellent talk and I was in the audience!

A graphic showing the concept of mapply in R, with multiple input vectors being paired and processed by a function returning a single output vector.

Just published my new R article: 'Mapply: When You Need to Iterate Over Multiple Inputs'! 🚀 If `sapply` doesn't quite cut it for your multi-variable iterations, `mapply` is your friend. Learn to pair inputs beautifully. #RStats #Mapply

✨ We launched a new installation page for DuckDB!

🚀 The new page lets you install the latest stable DuckDB release with just one or two clicks. If the defaults don't fit your use case, no worries: alternative download methods remain available for many clients.

🤩 My code produced when using LLMs to work on #rstats code got waaaaay better after I read this blog post by @simonpcouch.com on his Claude setup!

Volleyball Statistics for Irvine and Stanford's 2025 MVB season

I had the idea to add distributions to my volleyball summary tables today. Thanks to @richmeister.bsky.social's gt, @mjskay.com's ggdist, and @themockup.blog's gtExtras packages! Took awhile but got there eventually!
