I just made my first-ever contribution to R itself, fixing `seq.int(along.with = NULL)`. Try it yourself (the result is absurd!) 🐛 📖 I wrote about it here: mitchelloharawild.com/blog/r-dev-d... #rstats

Bugfixing R at R Dev Day 2026 – Mitchell O’Hara-Wild

My first R core contribution, fixing an absurd seq.int() bug that produces massive sequences instead of empty vectors.

There's still time for a last-minute registration for WOMBAT, happening next week! I'm very excited for lots of #DataViz and #RStats talks, alongside lots of other great sessions 📊 (and meeting more internet friends IRL or course!)

LLMs have been the most disruptive change in my +10 years of teaching data skills - for better and for worse. Students use LLMs to ask questions, debug code, and sometimes do entire assignments. They're great, but too often are abused to shortcut real learning. How are they used in your classes?

⚡ Today's 5-minute lightning talks at #useR2025 solved a problem I've had for 7 years! I created {hexwall} for the useR! 2018 feature wall of hex-stickers. @liomys.mx's {hexsession} package is everything I wanted for hexwall - hexagons arranged in HTML, CSS, and JS 🤩 👉 github.com/luisdva/hexs...

My day 1 #useR2025 highlight was the Positron class, I’m officially a convert now. 🤓 Why? 🐇 Positron is fast! ⌨️ RStudio keybindings 🎨 Command palette (Ctrl+Shift+P) to find any IDE feature 🏡 Remote-SSH runs code on my home server, anywhere! 🤖 The Positron Assistant integration is seamless #rstats

Day 1 at #useR2025 was a blast! It's awesome meeting new #rstats users and catching up with familiar faces. I was amazed to see the hex-sticker map of North Carolina, made with code I wrote for useR! 2018 in Australia. See how maps like this are made in R here: mitchelloharawild.com/blog/user-20...

🎉 WOMBAT is a fantastic event and I'm proud to be co-organising it this year. It's a great opportunity for us to share the latest open-source software and techniques among data analysts from academic, industry, and government.

There's so many parallel sessions at #JSM2025 that it's hard to choose where to go, so I web-scraped the schedule and made a chatbot to help. I've made it public, so hopefully it can help you too - try it out 👉 shiny.mitchelloharawild.com/jsm2025/
