I'm speaking at posit::conf(2025) in Atlanta Sept 16-18

I'm hoping you'll join our session on Strengthening the R Ecosystem at posit::conf(2025) on the Thursday morning!

Find out about the hottest new thing in the tidyverse: "purrrfectly parallel, purrrfectly distributed" (yes, it's something about cats).

A screenshot showing the Logfire tracing UI with traces from a Shiny app using ellmer, httr2, and mirai on the left and some attributes on the right.

A Shiny chatbot with a conversation about the weather in Atlanta, GA. It clearly serves as the source of the traces in the first image.

More #rstats + OpenTelemetry news: @schloerke.com finally got all of the async issues in {ellmer} and {shiny} sorted out and tracing now works!

Here's what combining {shiny} + {ellmer} + {httr2} + {mirai} + {otel} looks like today.

(All credit for the screenshots to @schloerke.com.)

{otel} + #rstats is becoming a crazy partnership.
This project has driven me to use/write {promises} in ways that makes my 🧠 ache 😅. The reward is worth it!

See you at #PositConf2025 where I'll talk about this in more detail

I've been reading the internals of {ellmer} and writing about it in my blog, and it's been fun seeing how all the pieces come together.

#rstats Anyone notice the new "Ask AI" feature on all the tidyverse package websites? 👀👀

I was loving Claude Code... until I tried it with #rstats. Constant errors, wouldn't use the tidyverse even when asked, "optimized" functions were slower.

Frustrated, I started a session just to teach R to Claude and summarize what it learned into a CLAUDE.md file gist.github.com/sj-io/3828d6...

Excited to share my newest quarto revealjs plugin: imagemover

Easily reposition and resize images directly in your quarto revealjs slides for a much smoother slidecrafting experience

Thank you! There is more to come in the blog series!

This looks like a great playlist. Anthropic released its developer conference. The conference included a variety of talks, keynotes, and tutorials focusing on Anthropic API, tools, MCP, prompt engineering, and vibe coding.

New #rstats blog post: Deep Dive into ellmer: Part 1.

I explore the source code behind ellmer's starter workflow - creating a new Chat object and calling the $chat() method.

www.howardbaik.com/posts/deep-d...

Thanks to @hadley.nz , @grrrck.xyz, @atheriel.bsky.social, and others for 🐘 ellmer 🐘 !

That's a very good reason 😂

Just out of curiosity (I've been tracing the ellmer source code to learn), what's the design choice behind the new streamlined chat() function?

ellmer 0.3.0 The newest version of ellmer introduces a simpler `chat()` interface that can works with any provider, a bunch of improvements to tool calling, and a handful of smaller quality of life improvements.

🐘 ellmer 🐘 makes it easy and fun to use LLMs from #rstats, and 0.3.0 is out now. Read about the new streamlined chat() function, improvements to tool specifications, and more at www.tidyverse.org/blog/2025/07....

New blog post! @posit.co Positron doesn't use Rproj files tofor #rstats projects—instead you open folders in the IDE directly. Opening folders can be a little tricky though. This shortcut lets you right click on a folder in macOS Finder to open a it in Positron! www.andrewheiss.com/blog/2025/07...

Thanks to everyone who responded to my question about what folks should know about using LLMs to generate #rstats: I've summarised the feedback with a few of my thoughts at gist.github.com/hadley/77d42...

Putting myself out there a bit. Honest request from an open-source developer:

Can I please ask you to encourage people you know to stop with the "any updates on this?" discussion post? Every post like that genuinely makes me die inside a little bit.

I'll try to explain in this thread. 1/

Awesome, thanks for your hard work on {ellmer}!

Ah okay, that makes sense. Thanks for the helpful reply.

Hey Charlie, what's a good resource to learn about event-driven async and modern communications, and anything else that serves as the foundation of mirai?
