A Quarto document in RStudio with the author field set to "Andrew Heiss"
hahahaha just got an email from someone who was using Claude to generate a boilerplate #QuartoPub document and the LLM *used my name* as the author. The computers are literally trying to be me now 😂🤣🙃🫠
The source of the standard Rust Hello World program with the generated assembly before and after the change. The before version has 11 instructions and stores 56 bytes on the stack. The after version has 3 instructions and stores no data on the stack.
🦀 I've improved the implementation behind all the string formatting macros in Rust: println, panic, format, write, log::info, etc. (Everything using format_args!().) They will compile a bit faster, use a bit less memory while compiling, result in smaller binaries, and produce more efficient code! 🎉
Image saying Typst 0.14. It has a holographic effect. The background is a pattern of checkmarks, at the top, it changes to a pattern of the string "0.14". The horizontal bar across the top reads "Title Elementm Skewed Fractions, Table Subheaders, Accessible Documents, Character-level Justification, PDF/A compliance, PDF Images, Typed HTML API"
Typst 0.14 is out now! Get ready for production with accessibility, PDFs as images, character-level justification, and more. Learn about more of the highlights in Typst 0.14 in the thread below ⤵️
🍩 What if climate looked like a donut? 🌍
Here’s a bunch of cities turned into a sweet dataviz experiment.
🟡 → comfy zone
🔴 → hot
🔵 → cold
Why a donut? Let me explain 👇
a table about lemurs
a table about students and schools
a table about wines
{tinytable} 0.14.0 for #RStats makes it super easy to draw tables in html, tex, docx, typ, md & png.
There are only a few functions to learn, but don't be fooled! Small 📦s can still be powerful.
Check out the new gallery page for fun case studies.

I'm exited to announce a new resource about making slides with quarto and revealjs. This book is the combination of all the work I have done in this area, reordered and polished up
There isn't a lot of new information yet, but this format allows me to add more easily

This week #TidyTuesday exploring a curated collection of recipes collected from Allrecipes website. I created donut chart subplots to look like plates and added a fork and knife image to each.

A shout out for @nrennie.bsky.social fab book on data viz! nrennie.rbind.io/art-of-viz/
At @okfn.bsky.social we are looking for a short-term R Developer. The work is exciting and important, advancing a humanitarian mission! Apply or share with others!
An arrow with a LaTeX equation
Trigonometric functions and a unit circle
A bivariate change model with structured residuals
A hierarchical model of cognitive abilities
Now on CRAN, ggdiagram is a #ggplot2 extension that draws diagrams programmatically in #Rstats. Allows for precise control in how objects, labels, and equations are placed in relation to each other.
