New blog post! Ever wonder what geom_histogram is actually doing? How about geom_boxplot? In celebration of the release of #ggplot2 4.0.0 (ggplot8?), I explore the relationships between the “geoms” and “stats” offered by the core {ggplot2} functions. #rstats

Our new paper, “A neural compass in the human brain during naturalistic human navigation” is out in @sfnjournals.bsky.social! First-author @zhenganglu.bsky.social led the charge, with Josh Julian and collaborator @gkaguirre.com. www.jneurosci.org/content/earl...
What makes humans similar or different to AI? In a paper out in @natmachintell.nature.com led by @florianmahner.bsky.social & @lukasmut.bsky.social, w/ Umut Güclü, we took a deep look at the factors underlying their representational alignment, with surprising results. www.nature.com/articles/s42...
Dimensions underlying the representational alignment of deep neural networks with humans - Nature Machine Intelligence
An interpretability framework that compares how humans and deep neural networks process images has been presented. Their findings reveal that, unlike humans, deep neural networks focus more on visual ...

Mastering typefaces and fonts in #rstats has always been harder than it should. I have tried to collect much of my relevant knowledge in this deep-dive blog post so you can spend your time picking the right typeface instead of cursing at the computer
Fonts in R
Taking control of fonts and text rendering in R can be challenging. This deep-dive teaches you everything (and then some) you need to know to keep your sanity

I promised to write about my thoughts on the status of the field of neuroAI, some of the big challenges we are facing, and the approaches we are taking to address them. This is super selective on the topic of finding a good model but in my view it affects the field as a whole. Here we go. 🧵

Über 350 @rasenfunk.social Hörer*innen haben die Tabelle der Männer-Bundesliga getippt. So sieht die Verteilung der Tipps aus. Sehen wir drei Zweikämpfe in den Top 6? Danke fürs Teilen der Daten, @gnetzer.bsky.social! #rasenfunk #ggplot2 📊
Verteidigt Leverkusen seinen Titel? Stürzt Stuttgart ab? Rafft sich der FC Bayern? Beginnt beim BVB eine Ära? Wir blicken mit @evabohle.bsky.social und @kalorineki.bsky.social auf die Saison voraus – inklusive Tabellentipp: rasenfunk.de/bundesliga-m/468 #bundesliga
📊When teaching or giving a talk, do you like presenting plots step by step, revealing e.g. one group at a time? This is often useful for walking through complex results. I made a R package that makes it extremely easy to do this! ggreveal: Reveal a ggplot incrementally #rstats #dataviz #ggplot2
Reveal a ggplot incrementally
Provides functions that make it easy to reveal ggplot2 graphs incrementally. The functions take a ggplot2 object and return a list of plots showing data incrementally by panels, layers, groups, the va...

Where are all the ggplot2 folks? The ggplot feed is almost empty 😢 Let's make this the new platform for all the wonderful visualizations created with #rstats 💪
I've just created a ggplot2 feed 👨💻📊👩💻 Give it a follow if you want to see relevant content related to your favorite code-first data visualization library 🙌 bsky.app/profile/did:...
Our new paper is out in Nature Comms. Great work by Alex Nitsch, which shows grid-like encoding of an abstract value space! www.nature.com/articles/s41...
Everyone needs to know about `easystats` in R It is so much fun to use and then share with students Teaching on regression and just used the check_model() function and look at this beautiful figure
Hello hello! Do you like/love the work of my team and me? Want to work on the intersection of genes, the brain, and social behavior? (in human neuroimaging). I have a PhD position available (start early 2024) shorturl.at/axDNT
