New favorite Positron/VS Code setting: "editor.emptySelectionClipboard": false

Accidentally pressing Cmd+C with nothing selected will no longer select the current line

Oh my goodness it is just a little baby ❤️

Merry December folks!

Wanna know your most used and co-dependent geoms this past year?!

I've built "Spotify Wrapped" for {ggplot2} that produces you an interactive story and analytical tools for your geom usage! #rstats

Build your own report by following the docs:

Come join us! We are gonna have fun learning and doing coding puzzles

Oh no!!

OMG it is so cute! so little and void! do you know how old she is?

And I'll be going in fresh! won't be doing any Advent of Code before the 2nd!

A festive digital illustration features the blue R logo wearing a red Santa hat with white trim on the left. To its right stands a green Christmas tree made entirely of curly braces arranged in a triangular shape. White and light-blue %>% pipe symbols float across a dark blue, starry background like snowflakes. A speech bubble above the R logo says “Ho Ho Ho! 📦” in red text. At the bottom, white text reads: “R Package Development Advent Calendar 2025” and below it, “25 Days of Coding Magic • Dec 1–25.”

🎄 ANNOUNCEMENT: R Package Development Advent Calendar 2025! 🎄

Starting December 1st, I'm launching a 25-day journey through modern R package development. here's why you should follow along 🧵

I'll second this. Once you have a template up and running, producing content gets very fast!

Posit’s progress and renewed commitment to the Open Source Pledge - Posit Posit continues its Open Source Pledge, investing heavily to support the open-source data science ecosystem.

I am tremendously grateful for open source, as it’s had such a huge impact on my career. That’s one of the reasons I’m so happy that Posit has committed to the @opensourcepledge.com. Read about our contributions to non Posit projects at posit.co/blog/posit-o....

🔦 added a 'highlight_mode' to hexsession.
Dim all images except the one hovered over.

Thanks to @emilhvitfeldt.bsky.social for the idea!

#rstats

testthat hex

testthat 3.3.0 is here! Major updates for #RStats testing include failure messages for easier debugging, 6 new specific expectations, and the SlowReporter to find your bottlenecks.

Heads Up: R 4.1+ is now required, and old mocking functions are removed.

making cute little hexes for my data packages just make sense

#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.

Q3 2025 tidymodels digest A summary of what has been going on for the tidymodels group in the mid 2025.

We are excited to share a few updates happening in tidymodels in this blog post!

I did a craft! cross stitched our little recipes cupcake

Screenshot showing usage of usethis::browse_package(), usethis::browse_cran(), and usethis::browse_github().

I'm reminded of how handy the usethis::browse_*() functions are and thought I'd remind people they exist. Choose from a menu of links or go straight to CRAN or GitHub. #rstats

Hyperparameter Fine-Tuning in tidymodels A view into the different kinds of hyperparameter tuning methods out there

I recently gave a talk on hyperparameter tuning in #tidymodels at Posit Day for University of Wisconsin. Nothing new in the slides but wanted to share regardless

emilhvitfeldt.com/talk/2025-11...

If you, like me, can't remember all the Sass variables when creating #quarto #revealjs slides. I found a semi hacky way to help myself here.

Using code snippets in VS Code & Positron allow us to get pretty good completion in our style sheets

the only experience Californians have with umbrellas is listening to that one Rihanna song and it shows. I'm surprised i still have 2 eyes left

don't get me started on books!

Buying crafting material and using crafting materials are two separate hobbies

Come work with us! We are so excited to announce this new position. With the same core goal; making modeling easier for users

you are on fire recently!

100% i find that fixing many mistakes are faster than pointing them out

oh no, i had another idea
