What's the current state of remote parquet-querying tools (duckdb, arrow, maybe polars) and WebR? That is, if I want a WebR/Shinylive app to query a remote parquet file and only transfer the query results? Or is the way to go, say, loading duckdb's WASM build and have a shiny call it via eval_js? Any examples?

I was very happy that i managed to get to compile htslib for the #webr environment and the duckhts bundle in the #RStats package, but then i see that i incorrectly assumed that the #DuckDB platform was wasm_mvp, it is Linux_i686_musl instead

This IS the droid you're looking for.

webRoid v1.0.0: a nearly full-featured R environment running natively on your Android phone or tablet.

Console, editor, plots, packages, 9 themes:no server, no cloud, no Jedi mind tricks. Just R on your device.

Tested extensively on emulators. Your actual device? The Force is strong, but no promises.

webRios started as "what if #rstats just worked on your iPhone or iPad" and now it has a whole documentation site. Feels like the app grew up a little today.

Uh-oh, these might be the droids you're looking for...

The number one request after every webRios demo was Android support. Early stage, but we have a working R console inside a native Android view.

webRios is live. #rstats on your iPhone and iPad.

I showed native R compilation on #iOS last week. Shipping it is another story (thanks, GPL). This version uses #webR 's #WebAssembly build instead. Different tradeoffs, but this one clears App Review.

{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.

{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.

Oh joy, #WebR is here to let you run #R #in your #browser, as if #JavaScript wasn't complicated enough already! 🖥️ Let's take a detour into this never-ending list of #modules, because who doesn't love a good module channel message payload proxy queue RMain RObject? 🤯 Thanks WebR, now we can finally plot our bad life choices in real-time! 📉😂

Woo hoo! The nloptr package is now supported in webR, which means we now have access to the lme4 package for mixed effects modeling! This brings a great deal of statistical modeling power to serverless R workflows. Great work @gws !

Where should you run LLM-generated code to ensure it's both safe and scalable? And why did we move from a cool in-browser WebAssembly approach to boring, yet reliable, cloud computing?

Our AI chart generator taught us that running R in the browser with WebR, while promising, created practical issues with user experience and our development workflow. Moving the code execution to AWS Lambda proved to be a more robust solution.

What is this? An R editor for ants?

@examplesWebR now goes full-screen because your data viz deserves better than a cramped iframe!

Click "Full-width" → no more squinting

Shoutout to @gws for another webR REPL update:

1. Shared code now auto-runs when you click links (by adding &a parameter to end of code=)
2. Choose your view: editor, plot, terminal, or files with ?mode='editor-plot'

Try it yourself: https://webr.r-wasm.org/latest/?mode=%27editor-plot%27#code=eJyb2LwkLzE3dXVoXklmSU5qiqFe0JKCxJKMXfoZ%2Bbmp%2BuWpSfGlxalF%2BsjyKYkliUe4CnLySzQMrQwNNAHRbxp%2B&a

#rstats #webR

Experimenting with `@examplesWebR` - a new #roxygen2 tag that makes #rstats package examples interactive!

Instead of static code blocks, users get "View in webR REPL" buttons that open examples in their browser or the embedded webR REPL. No R installation needed!

Still WIP (🚧 ) since the main challenge is distributing dev packages for #webR (non-CRAN versions).

Would love input on the best approach! Here or:

https://github.com/coatless-rpkg/rocleteer/pull/1

#webR now has shareable links! Just like #Shinylive's editor, you can instantly share #rstats code snippets with colleagues.

Thanks to @gws (webR creator) for adding this awesome feature to webR Latest (0.5.4-dev)!

Try it out with this demo snippet: https://webr.r-wasm.org/latest/#code=eJxVks9u1DAQxg%2FccuUFRi5CiQi7W4pAQuoBrdpyaCXYHrggRU4ym1j1n8iebBquPAHv0CNvwJn3YrxJt9tDZMfzfeOZn%2Bf3rwcrDf4JrfT4tkbjFpuHTlL7d9k6g8sBy6IP6JfPBLUk%2Be%2FFyxO4drKG9DXUbrCa9xk0TacdvYOtdwbYvYENdi4ocn5MtCq99GM6i7IkOYG1R0kIEkIlidBDDMGgqAXyaGvQyiKQg9C6ASrpAbdbVSm01TgpQjLlSw1xOOQgMaT3cA4D5TDyaromh8pp5%2FlnKyuuJa1GnWUZvEkAGnSm6JyylAb1E1lzxjl010rerhYfj1TBOEdtapBaV3NUaCNyCNFz%2Bfn69uLpGlFLf1fqHsVk5%2B40FvtosVNe1SoUdRrZR%2FF65C5r9GFWa1mGlFcAUqQnCXf%2BHVXTEuzCAi571HBxICHyvTr05cHwBeVOMc%2FIBCiSZIglgsYQYBvtjyBpdkdmYr4jPV2tVqDLkM3BCFLcKHZDx1mvpNbOCg5NFVOLBgujrDJSp0dnUxvxfRaPpaHmc0sF4f0B%2Ben7PD7NvvLS6Vpk%2BZPxqK1n3gPsxsvxw0pksZw4VN96Vd0xDWN43CCQpJDweKXidjr6BGvnPWpJylmGQgOi5XHdty4Z1c3XKzjnp93X4F1va77MzxP2Kg7WvOXZynI440%2F8sCL7DyCdEO0%3D

{quarto-webr} v0.4.3 "Bumpity Bump" is now available - a maintenance release that bumps to R 4.5.1 by default (via webR 0.5.2).

New maths/art blog post! Partly with the goal of demonstrating how awesome #webR is.

I describe making carpet patterns like the image attached, with all of the code running in the browser so you can generate random outputs, change parameters etc.

Even runs perfectly well on my crappy phone! It's going to be interesting to see how this alters stats education, reporting etc.

New on my blog: Adding Multiple choice quiz to #QuartoLive Tutorials

I was working with #Webr interactive code chunks for tutorials, and I wanted to add a multiple-choice quiz, as we have with the learnr package.

Here is my "home made" solution: https://yabellini.netlify.app/blog/2024-09-29-quarto_live_quiz/

If you have a better way, I will be grateful to learn.
