posit::conf(2026) is outta here! 👋 From Wes McKinney's AI keynote to Quarto slides, Shiny apps, & termite colonies, Day 2 was radical. Share your photos and reflections with the hashtag #PositConf2026 ❤️ See you in Seattle Sept 13-15 for posit::conf(2027). Until then, keep it real!
A speaker wearing glasses, a black t-shirt, and dark jeans stands on a brightly lit stage during a presentation. Behind him, a large textured wall is illuminated in warm orange light, displaying white text that reads "posit conf(2026)". The silhouettes of audience members are visible in the dark foreground.A crowded conference hall filled with people sitting at round tables during a lunch or networking session. Feather banners with numbers and the phrase "Birds of a Feather" mark different table sections throughout the room. In the foreground, several attendees are seated around a circular table with plates of food and drinks, engaged in conversation.A woman wearing a pink conference t-shirt and a man with glasses leaning over a small round table at an event booth. The woman is holding a smartphone and smiling while looking at it with the man. On the table sits an open laptop facing away from the camera, along with small promotional materials. In the background, a large dark blue banner displays branding for "Posit Assistant" and "Positron" along with the text "Work as fast as you think."

Headed to Houston for #positconf! I can’t overstate the impact that @posit.co’s opensource products & packages (RStudio, Positron, tidyverse) have had on me as a journalist & data nerd 🤓 Thrilled/terrified to be giving a keynote presentation on Tues. If you’re there, say hello! conf.posit.co/2026/
Keynote Session by Christine Zhang, Graphics Editor at The New York Times: How to Be Clear When You Can’t Be Certain
Sometimes, data visualization is about using charts to illustrate a key point or conclusion gleaned from analyzing the data. But what if you’re not sure what the conclusion is? Presenting examples from news reporting on the topics of elections, polling and economics, I will talk about how I have grappled with uncertainty and how to communicate it to the public.

My favorite little feature from the Positron 2026.08 release: we now check your R scripts (and Python scripts, Quarto files, etc.) to see if they refer to any packages/modules that are needed to run the script but aren't installed. If they do, you'll get a little notification and an install button!
