I'm exited to announce a new resource about making slides with quarto and revealjs. This book is the combination of all the work I have done in this area, reordered and polished up

There isn't a lot of new information yet, but this format allows me to add more easily

SynergiZing ML & LLMs in R — tidymodels, RAG, Shiny | Athlyticz Waitlist open for Athlyticz’s async R course: tidymodels + LLMs (RAG, tool-calling, evals) and Shiny/vetiver deployment—by Nic Crane & Christoph Scheuch.

We’re thrilled to have @niccrane.bsky.social and @christophscheuch.bsky.social join our team to co-develop our flagship async course, SynergiZing ML & LLMs in R.

We’ve also welcomed @albertrapp.bsky.social to lead our monthly membership track.

ggplot2 4.0.0 A new major version of ggplot2 has been released on CRAN. Find out what is new here.

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

Another challenge is being obsessive about function names and consistency since in R we typically load everything into the same namespace. In Python, I’d probably take a different approach, since it’s more common to organize things into (sub-)modules.

Great idea for a post! The tricky part is that you often figure things out along the way (e.g. column / parameter names), which then forces changes in other packages (i.e. breaking changes / soft deprecations). A meta-package that loads the rest is easy to set up thanks to the tidyverse 🙏

Link to package docs: tidy-intelligence.github.io/r-econdatave...

Big milestone: {econdataverse} is now on CRAN #rstats. Install & load multiple #EconDataverse packages in one step, just like the {tidyverse} 🥹

Wasn’t it some Excel mess? Like hitting row limits and wrong references. Guess the first step would be a code-first approach 🫠

nanonext 1.7.0 nanonext is a communications and concurrency toolbox that facilitates fast, powerful and reliable data exchange in polyglot data science workflows.

nanonext is a messaging and concurrency toolkit, connecting R to polyglot data science pipelines involving modules written in Python, Rust, Go and C++ etc.

#RStats #tidyverse

Looking forward to my first pure #Python conference ever at PyData Berlin 🐍

If you are interested in getting to know Shinylive and WebAssembly in Python, feel free to join my talk tomorrow at noon titled „Building Reactive Data Apps with Shinylive and WebAssembly“ ✌️

The first vignette offers a detailed look at what’s possible with {datacommons} in #rstats: tidy-intelligence.github.io/r-datacommon...

Another new CRAN release with @tealemery.bsky.social 💪 {datacommons} is a wrapper for the Google Data Commons API v2, which provides unified access to global public stats in a knowledge graph, thus reducing data-wrangling pain.
Feedback as always very welcome 🙏

Working hard at more R packages 😅

GitHub - Teal-Insights/r-imfweo: Seamless Access to IMF World Economic Outlook (WEO) Data Seamless Access to IMF World Economic Outlook (WEO) Data - Teal-Insights/r-imfweo

New #RStats package on CRAN: {imfweo} (w/ @tealemery.bsky.social) gives easy access to IMF’s World Economic Outlook. It's part of the #EconDataverse, helping economists + financial professionals work with sovereign-level data. Feedback welcome ✌️

Happy to announce ✨quarto-revealjs-editable✨

This fully supersedes the imagemover extension, as I back then didn't realize the potential. You can now also move, resize, change font size and alignment for text in your slides

Trigonometric functions and a unit circle

A bivariate change model with structured residuals

A hierarchical model of cognitive abilities

Now on CRAN, ggdiagram is a #ggplot2 extension that draws diagrams programmatically in #Rstats. Allows for precise control in how objects, labels, and equations are placed in relation to each other.

A testimonial quote on a dark blue background. The text reads: “Positron feels like stepping into the future of data science. I work in both R and Python daily, and switching between projects has never been easier. With built-in version control, a lightning-fast data explorer, and automatic code formatting, my workflow is pure joy — building apps, packages, reports, or teaching materials has never felt this seamless.” — Christoph Scheuch, Founder, Tidy Intelligence.

I’m a big fan of the Positron IDE, so when @rachaeldempsey.bsky.social‬ asked me to provide a testimonial, I didn’t hesitate 🙏

What’s the problem with webR in Safari? How about Chrome?

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

Shiny Apps in the Azure Cloud A practical guide to deploying Shiny Apps in the Azure Cloud

By popular demand over on LinkedIn, I’ve kicked off a series on deploying R/Python projects to Azure.

First up: version control, containerisation, build pipelines & hosting.

Should I include #Python or keep it focused on #rstats?

Starting my new position as #data #editor for the Review of Financial Studies together with @christophscheuch.bsky.social. Very excited for all that is to come!

Introducing TidierErrors.jl, an experimental #JuliaLang package that makes error messages tidier with the help of LLMs (with support for local LLMs!)

Fantastic news! Does the ws-proxy server require a lot of resources (RAM, CPU) or is it just a minimal instance routing requests?

#rstats has anyone added a new provider to ellmer? I see that it’s doable but I’m hoping to see if someone has blazed that trail for me and I can follow in their footsteps steps.

New on CRAN: {oecdoda} 📢 Access & analyze Official Development Assistance (ODA) data from the OECD API in R - inspired by Jorge Rivera’s {oda-reader}. Part of #EconDataverse. Feedback welcome 🙏

The #EconDataverse keeps on growing ✌️

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....
