Oooof

I'm at #PyConUS 2026 🙌 if you are here too please come by and say hi! would love to hear what you are working on, will most likely be found at the Posit booth

"Posit Assistant and NES reflect our learnings from twenty years of building for data scientists and researchers. As the token subsidies end, the differentiator between products becomes more about the value those products provide, and we think we’re ahead in value for the data community."

Super excited to get this at my door today! Ursula Laa and my book on exploring high-d data and models is in print! Book website is www.routledge.com/Interactivel... if interested I think my 30% discount code might work for you - msg me. Time to update dicook.github.io/mulgar_book/ too! #rstats

If I were Campar, I would insist on *Doctor* Sticks With Meat On Them. #CaptivesWar

The newest release of Posit Assistant, an agent for coding and data analysis, includes a "data cleaning mode." When enabled, the agent will run quality checks and surface decisions about e.g. import issues, factor levels, etc to the user. In the AI Newsletter: opensource.posit.co/blog/2026-05...

We have friends everywhere.

It's been about 8 years but better late than never!

We've had a flurry of new tidymodels #rstats releases. Here's a summary of what's been going on with a focus on ordered outcomes and quantile regression. opensource.posit.co/blog/2026-04...

I managed to install panache (panache.bz) and for now I only got it to do one thing, but it is one thing that is really nice to do with a one liner: put every sentence in a quarto document on a newline. So the economy of a paragraph is visible at a glance. #writing #quarto

I am excited beyond description to lift the veil on what we have been working on in 2026: Please meet ggsql! A new extension of the SQL language for creating visualisations using the grammar of graphics. Read all about it in the blog post or visit the website at ggsql.org

I loved reading this. It’s so well written!

How to tell if a statistical method really works? Monte Carlo simulations give a clear answer. Instead of relying on one dataset, you generate data repeatedly and compare methods across many runs. New module in the Statistics Globe Hub: statisticsglobe.com/hub #Statistics #DataScience #RStats

The panache #quartopub formatter and linter by @jolars.co is excellent! Very configurable and uses external tools (e.g., air or ruff) to format code blocks. panache.bz

#quartopub version 2 is being cooked up in the lab. @cscheid.net has a post discussing the why and when (with some hints about some related future projects) quarto.org/docs/blog/po...

For me, this could not have been any more on target.

We've released the first version of our tabpfn #rstats package to CRAN. This is an interface to the Python #TabPFN package. tidyverse.org/blog/2026/03... The model is a pre-trained deep learning model that has performed exceedingly well on every data set I've tested it on.

Our list of 2026 #rstats and #python summer internships has been posted. We can't wait to work with you and make great things! tidyverse.org/blog/2026/03...

We’re thrilled to welcome Sara Altman and Simon Couch of the Posit AI Core team to the #positconf 2026 keynote stage! They’ll be sharing a practical, hype-free look at how AI is being thoughtfully integrated into the tools you use every day. ✨ See what’s next for AI in open source: pos.it/conf

Cool little details about how to structure tree splits. And don't worry, the cat is not in the dryer. I checked.

I'm over the moon excited to the release of 0.5.0 of orbital 🛰️ This release adds full support for boosted tree, faster creation of orbital objects, optimization of execution! We can finally reliably predict with a xgboost model from a database! tidyverse.org/blog/2026/03... #rstats #tidymodels

something big is coming 🛰️

🤩

I presented at Shiny in Production 2025, an incredible conference hosted by @jumpingrivers.com up in Newcastle! I was glad to share the very latest from the Shiny team directly. The topics were bleeding edge at the time, so still new and relevant now. My video: www.youtube.com/watch?v=vxai...

We are covering 40 people's travel, lodging, and registration for posit::conf() this fall! If you are from a group that is underrepresented in data science or open source, please consider applying for the Opportunity Scholarship—we'd love to have you join. posit.co/blog/apply-t...

March's tabular playground #rstats #databs #tidytuesday www.kaggle.com/code/jimgrum...

#tidymodels now has its very first cheatsheet! "Preprocessing data with {recipes}" is now available in Web and PDF versions here: rstudio.github.io/cheatsheets/... #rstats #posit #rstudio

A very helpful post on AI helpers, especially if you are new to AI and Claude

Too bad Claude can’t shovel snow.

Here’s a clip from Max Kuhn (@topepo.bsky.social) of Posit breaking down how we can truly quantify LLM performance using a clear, generalizable framework. See the full conference talk here: youtu.be/TQKbaIR-8J4 #AI #MachineLearning #DataBS

Want to check if code using #GenAI generates the responses you want? Here's how to automate LLM evals with the {vitals} #RStats 📦 by @simonpcouch.com @posit.co My latest at #InfoWorld: www.infoworld.com/article/4130... #LLMs

With bookdown.org being decommissioned, I've been working on converting #rstats books from #bookdown to #quartopub. After spending a lot of time with Claude to get it right for my two books, here's a repo that might help you do the same (especially with Claude Code): github.com/topepo/bookd...

Last week we released dplyr 1.2.0, but we left off something VERY important 🙂 `dplyr::if_else()` and `dplyr::case_when()` are now up to 30x faster and use 10x less memory! We dive into how we achieved these numbers in this new #rstats post! tidyverse.org/blog/2026/02...

For more than a year I have been working on a brand new Jupyter Notebook editor for Positron. This is a ground-up build of a new Jupyter Notebook experience built to leverage all the knowledge and tools Posit/Positron brings to the data science table. 🧵#jupyter

dplyr 1.2.0 is out now and we are SO excited! - `filter_out()` for dropping rows - `recode_values()`, `replace_values()`, and `replace_when()` that join `case_when()` as a complete family of recoding/replacing tools These are huge quality of life wins for #rstats! tidyverse.org/blog/2026/02...

The hexagon here is priceless 😎 taf-society.github.io/caretForecast/ #rstats #timeseries

Tomorrow at the Data Science Lab 🧪 we are hearing from the amazing @theotheredgar.bsky.social about the {mall} package: Run Natural Language Processing against your #RStats tibbles or #Python Polars DataFrames for sentiment analysis, text summaries, and more! Join us at 12 pm ET: pos.it/dslab

I sent 200 pull requests using Claude Code and wrote about the experience. It's pretty wild! For dplyr releases, we send a PR any time we break an #rstats package. This release advances a lot of deprecated functions, triggering issues in many old packages! blog.davisvaughan.com/posts/2026-0...

We are excited to see that xgboost recently had a big CRAN release! We have worked hard on the tidymodels team to make sure you all have a smooth transition. Please yet us know if you are experiencing any issues with the releases tidyverse.org/blog/2025/12... #rstats #tidymodels

~~ making sense of academic statistics ~~ i wrote about the confusing relationship between statistics and data analysis, and also about how statistics relates to science #statistics #rstats #datascience www.alexpghayes.com/post/making-...

I'm excited to announce the newest release of {tidypredict}! This release brings for standardization to outputs, faster trees for parsing and prediction, and glmnet support tidyverse.org/blog/2025/12... #rstats #tidymodels

We’ve released two new tidymodels #rstats packages for feature selection: filter and important. tidyverse.org/blog/2025/11...

I’m not aware of an Arrow or Parquet format, but there is the ONNX format (see onnx.ai). Depending on the model, you could try Posit’s orbital project, which translates your model to SQL (see here orbital.tidymodels.org).
