Just dropped a WHOLE BUNCH of these somewhere👀👀👀 #positconf2025

Just wrapped up a talk at #positconf2025 about LLM evaluation with R! Such a joy to hang out with #rstats folks in person and hear about what others are working on. Resources and slides: github.com/simonpcouch/...

The always delightful @k-bott.bsky.social shares the educational principles of Posit Academy for teaching professionals in the wild: Practice that is: 💫 Repeated over time, 💕 relevant to their domain, 🪜 within their reach, and 👯‍♂️ conducted in a community. #positconf2025

I absolutely *love* that @simonpcouch.com mentioned using Google Sheets to easily supply input(s) and target(s) for evaluating #LLM quality {vitals} 🧸 Sometimes selecting right-sized solutions means deviating the "serious" data science techniques to get things done, creatively! #positconf25

@sara-altman.bsky.social and I just shared the second release of the Posit AI Newsletter! In this edition, a landmark settlement on LLM training data and copyright, the emergence of agentic browsers, and more. Read and subscribe on the Posit Blog: posit.co/blog/2025-09...

I hope no one is tired of seeing adorable #pawsitconf posts full of cute pets and punny talk titles, because @trevinflickinger.com helped his THREE dogs submit talks 😭 JUST LOOK AT THEM #rstats #python #databs #positconf2025

I am beyond excited to announce that ggplot2 4.0.0 has just landed on CRAN. It's not every day we have a new major #ggplot2 release but it is a fitting 18 year birthday present for the package. Get an overview of the release in this blog post and be on the lookout for more in-depth posts #rstats

People keep telling me they can't afford to attend #PositConf2025 next week, so I need to make a public service announcement: attending virtually is very affordable (or free!) & is amazing! Get registered & hangout with me on the Discord server!! #databs #rstats #python

I kinda feel like the president declaring war on an American city should be an uncrossable line, but I don't know what to do at this point. www.cnn.com/2025/09/06/p...

There's been a big push at Posit this summer to get high-quality OpenTelemetry support out to the #rstats community (a longstanding dream of mine). I think {mirai} is the first package release to showcase this work, and as per usual with @shikokuchuo.net, it was done in record time!

somehow I just learned there's a variety of blackberries called obsidian, and of course it makes the best jam stephango.com/quality-software

🚀 We’re excited to share the first edition of the Posit AI Newsletter! Curated by Posit’s Sara Altman and Simon Couch, this biweekly newsletter keeps you up to speed with what’s happening in the AI world, both at Posit and beyond. 📫 Read the first issue: posit.co/blog/2025-08...

Using the crap out of this extension as I work on my #positconf2025 slides and loooving it. Something tells me we'll be seeing some masterfully-placed images in #quarto slides at conf this year. :)

Two weeks to go 😬 I'll be presenting on the fun work I've been doing on spreadsheets + R #rstats #positconf

Sign-up for the next round of the rainbowR buddies scheme is open! Buddies will be paired/introduced on Sept 2nd 🌈👯‍♂️ If you're LGBTQ+ and code in #RStats, and want an opportunity to connect with someone else in the community (through a random pairing), then this is for you 😃 rainbowr.org/buddies

So stoked to share about the first release of the Posit AI Newsletter! @sara-altman.bsky.social and I have been working on a pilot of this newsletter internally for a few months now—an opinionated and pragmatic snapshot of AI news released every two weeks. First edition: posit.co/blog/2025-08...

odbc 1.6.2 is now on #rstats CRAN! A good few QOL improvements, especially for Databricks and Snowflake users: github.com/r-dbi/odbc/r...

Slides from my #rstats talk “Measuring LLM Effectiveness” at #dataconfAI with @simonpcouch.com. topepo.github.io/2025_NYR/ Video in about a month. Great conference!

In working on an eval for an experimental tidymodels AI assistant, I realized that today's frontier LLMs know much more about #rstats tidymodels than I thought. www.simonpcouch.com/blog/2025-08...

Does Jenny Bryan #VibeCode? 🤔 She shared on the Hangout that she's been thankful that she gets to learn #rust and #typscript in the age of #AI and these are her thoughts on #LLM use. (We really need a #RubberDuck emoji 🦆) #rstats #databs #VibeCoding #DSHangout #python

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...

We still have spots available for tidyverse dev day on Sept 19: www.tidyverse.org/blog/2025/07.... Please come along to contribute to the tidyverse and have a bunch of fun along the way! It's open to all, but is most convenient if you're coming to posit::conf or live near Atlanta #rstats

Such a cool post. At one point, Isabella writes about serving an LLM with ollama on a spare computer and connecting to it over the local network with ellmer!

Really, really excited to get to the next stage with Positron, including upcoming general availability of Positron in Posit Workbench! posit.co/blog/positro... #RStats #PyData #dataBS #datascience #positron

Oh hell yeah

some light teasing for an upcoming quarto revealjs plugin I have been working on

{hexsession} by @liomys.mx is fun and useful! Produces css/html snippets that tile hex logos nicely, e.g. to showcase your #rstats package projects. 😎 github.com/luisDVA/hexs... #useR2025

Excited for @davisvaughan.bsky.social & my talk tomorrow in which we will demo a shiny app we ✨ vibe coded ✨ up today, if you're at #user2025 stop by Gross at 10:30a tomorrow. Sneak peak 👇

#useR2025, sticker and some cool attendees 😁🤭

Welp, {chores} by @simonpcouch.com is an immediate install for sure. Basically it's {usethis} plus llm bundled into RStudio/Positron key encoding. Excited!!! 🧹🧺 #useR2025 #rstats #couchverse?

🧵 of takeaways messages and quotes....

I've had preview access to GPT-5 for a couple of weeks, so I have a lot to say about it. Here's my first post, focusing just on core characteristics, pricing (it's VERY competitively priced) and interesting details from the GPT-5 system card simonwillison.net/2025/Aug/7/g...

Check out our Modeling & ML with #RStats workshops at posit::conf! 🔢 Intro to ML w/ tidymodels @simonpcouch.com 🏗️ Feature Engineering & Tuning @topepo.bsky.social @emilhvitfeldt.bsky.social ↔️ Causal Inference @malcolmbarrett.malco.io @lucystats.bsky.social Learn more: pos.it/conf-2025-workshops

Anyway just saying

OMG I TRIED AIR. I TRIED IT & LIFE WILL NEVER BE THE SAME. @juliasilge.com recommended format on save, so I set up Air + format on save + auto save when focus leaves editor. This might be the thing that gets me using #Positron for both #Rstats & Python (currently only using it for #Python) #databs

We've released 4 new chapters of Applied Machine Learning for Tabular Data. Includes: Bayesian optimization, feature selection, model comparisons, classification metrics, calibration, #rstats computing sections, and more blog.aml4td.org/posts/2025-0...

The limited run of the #rstats stacks hex for this year's posit::conf is confirmed🥞🥞🥞 I'll have a batch of peaches & cream stickers, come say hi to pick one up! posit.co/conference/

🐘 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....

If you're worried about that messing with `git blame`, you can use `.git-blame-ignore-revs` github.com/quarto-dev/q...

Announcing sparse data support in tidymodels! #RStats users, get faster model fitting, less memory use, & efficient handling of big datasets with zeros. Check out blog: www.tidyverse.org/blog/2025/03... @emilhvitfeldt.bsky.social's SLC UseR talk: www.youtube.com/watch?v=l1zv...

mcptools, a package implementing the Model Context Protocol in #rstats, is now on CRAN!🌉 We see significant opportunity with MCP and, at the same time, want to note that it's still a nascent ecosystem with serious security risks. www.tidyverse.org/blog/2025/07...

this week in #rstats 🕺 - latest Claude Code thoughts 🤖 @simonpcouch.com - faceted {tinyplot}s 📊 @ereinbergs.bsky.social - {httr2} v1.2.0 🎯 @posit.co @hadley.nz - RAG with {ragnar}+{ellmer} ⚒️ @stephenturner.us @smachlis.bsky.social this and more below 😎 www.linkedin.com/pulse/week-r...

After a month or so of not using Claude Code much to write R code, I recently returned to using the tool most days. Giving coding assistants the ability to peruse #rstats package documentation via MCP is so, so helpful: www.simonpcouch.com/blog/2025-07...

the remainder of this skeet is organized as follows

#ragnar 0.2.0 is on CRAN #rstats! It has a MUCH improved chunker; markdown_chunk() picks better boundaries, builds context, segments by headings, and handles overlapping chunks. Oh, and ragnar_retrieve() can deoverlap retrieved chunks now. Website got a big update too: ragnar.tidyverse.org

The people call and I answer. Here are my thoughts on that developer RCT and the "AI slows down developers" claim. www.fightforthehuman.com/are-develope...

Drawing comparisons to Deepseek, a little-known company dropped an open-weights LLM Kimi K2 on Friday with some very impressive benchmarks. I tried it out and the vibes were bad. www.simonpcouch.com/blog/2025-07...

#tidyverse purrr 1.1.0 is out - now with parallel processing! Scale your #rstats map operations reliably and efficiently across multiple cores and even distributed systems. Powered by the mirai framework, this unlocks new levels of performance. Read more at: www.tidyverse.org/blog/2025/07...
