{webrarian} walked so {pyrarian} could... also walk? Ported #webr 's 4-panel editor to Pyodide. Already loading pandas and plotting with matplotlib in the browser. The librarians are going multilingual. #pyodide #python #wasm

{toggle} does one thing: adds a button to hide code output in #quarto docs. Took two versions to do that one thing well. Now it works everywhere... tabsets, callouts, nested containers, you name it. 📚 quarto.thecoatlessprofessor.com/toggle/ 🐙 github.com/coatless-qua...

{livelink} walked so {webrarian} could run. Mini browser-based #rstats environments powered by #webR and its 4-panel editor. YAML config, build, preview. Done. R package coming soon. #pyodide folks, stay tuned.

Shiny for R: GPL-3 → MIT ✨ Your dashboards are now legally chill. Deploy without consulting three lawyers and a ouija board first. #rstats #rshiny

Consider submitting a proposal to the (open access) Psychometrika special issue on Variable Selection for Complex Psychometric Data, with a proposal deadline of Jan 15. Full details:

Released a #Quarto extension for collapsible content blocks. Why? The {details} are inside. 📚 quarto.thecoatlessprofessor.com/details/ 💻 github.com/coatless-qua...

Turning another year older tomorrow and celebrating by releasing Quarto extensions into the wild. Gift to me, gift to you. And yes, if you've been peeking at my GitHub, you already know what's coming. Act surprised!

{ripper} dissects your #Quarto documents, extracting code blocks by language and leaving executable scripts behind. Supports #rstats, #python, #julia, and 13 other victims. For those who never stopped celebrating Halloween. 📚 quarto.thecoatlessprofessor.com/ripper/ 💻 github.com/coatless-qua...

One does not simply stay away from social media. I return with: R packages, portable R, Shiny/shinylive apps, Electron integrations, Python packages, Quarto extensions, LLMs, and blog posts. The code has been reforged. The roadmap is full.

Still fascinated with #webR and its potential for teaching stats Here students can play (even from their phones) and find out themselves how the p-value depends on sample size pakillo.github.io/LM-GLM-GLMM-... #rstats

@coatless.bsky.social also did that few months ago using another approach based on JavaScript. "Pick your poison" 🙃 github.com/coatless-qua...

Quarto has a way to collapse code, but what if you want to collapse code OUTPUT? The amazing @mickael.canouil.fr created an extension that does just that!!! Check it out! github.com/mcanouil/qua...

Nothing makes you feel vintage like your license getting moved to the retirement home directory. GNU put GPL 2.0 in /old-licenses/ causing #rstats packages to throw URL warnings. Somewhere a CRAN maintainer is rubbing their hands together, ready to trigger 847 email requests...

Flying to Istanbul to meet my SO's family felt like nervous excitement. Flying to California felt like possibility. Flying back home for a funeral feels like gravity remembering how to work. Now Illinois feels like living in a house where all the furniture is made of memories.

macOS 26 Tahoe + R 4.5.1: Keeps #rstats moving along on #macOS. Upgrade confidently, just remember to update Xcode CLI afterwards if using stan & compiled code.

R that travels light on #Linux: Portable R AppImages. Now working everywhere: your Ubuntu, friend's Fedora, cousin's Arch setup (btw) No sudo, no tears, just base R science ✨ (package support coming soon!) #RStats #AppImage #DataScience

RcppEnsmallen 0.2.22.1.2 on CRAN: Upstream Armadillo Changes blog.thecoatlessprofessor.com/software-rel... #rstats #rcpp #rcppensmallen #ensmallen

Linux support 🐧 Same #rshiny → desktop workflow on #Fedora 42 aarch64: shinyelectron::export() → #rshinylive → #AppImage → portable #Linux app Plot twist: no more "go buy yourself a real computer" moments - you get zero #rstats dependencies too! The condescending Unix users have won this round.

Core Shiny Application (Shinylive Layer): 61.9 MB This represents the base Shiny application code and dependencies Platform-Specific Packaging Overhead (ARM64): Windows: 300.1 MB macOS: 264.1 MB Linux: 304.9 MB Total Application Size by Platform: Windows: 362 MB macOS: 326.4 MB Linux: 366.8 MB

By request: Same #rshiny app → native #electron desktop app workflow now on #Windows11 shinyelectron::export() → #rshinylive → installer → app.exe [Worth the Parallels license to record this from my Mac] Still no #rstats dependencies for end users. Living the cross-platform life (virtually).

JJ Allaire & Charles Teague (of Posit fame) launched Meridian Labs, a nonprofit dedicated to frontier AI research and evaluation tools. Early focus: LLM evals + visualization & SWE Agent tooling for Inspect AI. meridianlabs.ai | github.com/meridianlabs-ai #AI #Research

Prototyping #rshiny apps to native #electron desktop apps: shinyelectron::export() → #rshinylive conversion → .dmg → Native Mac app Zero #rstats dependencies for end users! Early days but promising 👀

TIL about SciServer.org: Free scientific computing platform with persistent accounts (#NSF-funded). All the power of #JupyterHub without the setup hassle. Focus on building great teaching + research notebooks, not infrastructure! #OpenScience

{multideploy} is now on CRAN! 🎉 This #rstats 📦 streamlines file deployments across multiple #GitHub repositories. Update CI workflows, configs, and templates at scale with precision + automated PRs. Install with: install.packages("multideploy") CRAN: cran.r-project.org/package=mult...

Request fulfilled! Converted {macrtools::openmp_*()} #OpenMP suite into standalone shell scripts for #macOS: 🎯 Auto Xcode detection & OpenMP library mapping 🔬 Diagnostics tests 🧹 Safe uninstall 📦 Repo: github.com/coatless-she... 📝 Post: blog.thecoatlessprofessor.com/programming/...

We’re working on relicensing everything under MIT

TIL: The web framework licensing game is mostly MIT/Apache… except Shiny for #rstats went rogue with GPL-2 😅 Shiny for #Python: MIT ✅ Gradio: MIT ✅ Streamlit: Apache 2.0 ✅ Dash: Apache 2.0 ✅ #rshiny: GPL-2 🤷‍♂️ Anyone know the backstory here?

After my 6th cup of coffee, I've officially entered the owl dimension. My empty mugs have finally summoned their nocturnal overlord. We communicate only in hoots and caffeine-induced anxiety now. 🦉☕

Discovered Soap&Skin's 'Me And The Devil' and honestly sounds like my skincare routine took a VERY dark turn 🧴😈 www.youtube.com/watch?v=ZfWS...

Your main #quarto website repo shouldn't be a storage unit for every plot you've ever made 📦 #git #submodules: Give your figures their own space, keep your repo fast blog.thecoatlessprofessor.com/programming/...

Does anyone know of R packages that require license keys for certain features? Curious about packages with mixed open/proprietary functionality. #RStats #SoftwareLicensing

Finally, your R packages on #macOS can disappoint all your cores instead of just one of them at a time 😅 {macrtools} now installs & configures OpenMP with: `openmp_install()` and you're done! ⚡️ mac.thecoatlessprofessor.com/macrtools/re... #rstats #hpc

@harry.vangberg.name's wip/experimental #rstats editor looks promising for data science education - the clean interface with side-by-side code and output makes it easy for students to see immediate results and data structures as they learn R fundamentals. #edtech

Conda is there because of the chaos of system level dependencies in the python ecosystem In the R ecosystem, unless it is ubiquitous (and usually very stable) system dependencies (say libcurl, gsl etc), the standard practice it to vendor and statically link the native dependencies

I made a video on a topic that seems to misunderstood by a lot of students taking introductory stats classes. This is my first video, so it was a lot of experimenting and a lot of learning. Any feedback/suggestions are appreciated. #statistics #datascience #education youtu.be/1r3SW8UN1vc

Beta tested molab this week and it’s absolutely marimo-nificent! 🎉 Finally, a Colab alternative that doesn’t make me miss Jupyter (because it’s marimo!) ☁️ marimo.io/blog/announc... RIP my local compute struggles, hello cloud paradise 💅 #marimo #molab #datascience #ML #python

TIL how to add notebook cells running on @pyodide.org to Quarto projects, such as my blog: alonsosilvaallende.github.io/til/posts/20... It's very easy to change the Pyodide version if needed. Thanks @coatless.bsky.social for this great Quarto extension
