webRios v1.1 is in the queue. Soon.

App Store Connect screenshot showing the webRios app with version 1.1.0 in "Waiting for Review" status.

webRios is live. on your iPhone and iPad.

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

Promotional image for webRios showing the app icon and an iPhone displaying the R console. The console shows example R commands with syntax highlighting: basic arithmetic (1 + 1), a print statement saying 'Hello from iOS!', a warning message in orange reading 'Uh-oh, I'm in the Apple-verse?', an error message in red with the HAL 9000 quote 'I'm sorry, Dave. I'm afraid I can't do that.', and a plot command.

{webrarian} walked so {pyrarian} could... also walk? Ported '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 environments powered by and its 4-panel editor. YAML config, build, preview. Done.

R package coming soon. folks, stay tuned.

Oh joy, is here to let you run your , as if wasn't complicated enough already! 🖥️ Let's take a detour into this never-ending list of , 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 !

PSA for anyone starting to use #wasm #webR to share R code snippets: We have a new short URL for the webR app: webr.sh!

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.

I have just completed the release of the polars package for #rstats, which we have rewritten over the course of a year.

github.com/pola-rs/r-polars/re

It can be installed instantly from R-multiverse (even on #webr !).

Step 1: Write R code
Step 2: Share it
Step 3: Spend 2 hours helping someone install R and troubleshoot their environment

OR

Step 1: Write R code
Step 2: webR sharelink

Step 3: Profit ✨

Screenshot showing Firefox browser displaying a webR REPL interface in the foreground, with an RStudio session visible in the background. The webR interface shows decoded R files (main.R, functions.R, config.R, sample_data.csv) that were embedded in a shareable URL. The RStudio console in the background displays the encoded webR sharelink URL that packages all the local files. On the right side, R documentation is open showing help for the 'Create WebR REPL sharelink for multiple files' function. This demonstrates the workflow of encoding local R project files into a URL that can be shared and automatically reconstructed in a browser-based R environment.

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: webr.r-wasm.org/latest/?mode=%

Screenshot of webR REPL application running in a web browser. The interface is split into two panels: on the left is a code editor containing the R command 'plot(1:10)', and on the right is the resulting scatter plot visualization showing 10 points plotted from coordinates (1,1) to (10,10). The plot has 'Index' labeled on the x-axis and values from 0 to 10 on the y-axis. The browser interface shows typical web app controls including Run, Save, and Share buttons at the top

Experimenting with `@examplesWebR` - a new tag that makes 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 (non-CRAN versions).

Would love input on the best approach! Here or:

The right pane displays package documentation with a blue "View in webR REPL" button. A firefox browser window is open showing the WebR REPL interface with simple R code (1 + 1) and R session information including details about contributors, demos, and help functions. The interface shows the same rocletter package documentation as the first image.RStudio interface showing R package documentation with embedded WebR REPL functionality. The left pane contains R source code with roxygen2 comments, including a @examplesWebR tag and demo functions. The right pane displays package documentation for "Test WebR REPL Embedded Inclusion" with an embedded WebR REPL interface showing a ggplot2 example. The WebR interface contains code (library(ggplot2), ggplot(mtcars, aes(mpg, wt)) + geom_point() + theme_minimal()) and displays a scatter plot visualization. The bottom shows an R console with package loading messages in red text.

now has shareable links! Just like 's editor, you can instantly share 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: webr.r-wasm.org/latest/#code=e

Screenshot of webR REPL in a web browser showing R code for creating a scatter plot analyzing car weight vs fuel efficiency. The left panel contains ggplot2 code using the mtcars dataset, with points colored by cylinder count and a trend line. The right panel displays the resulting scatter plot with a clear negative correlation between weight and MPG. A modal dialog box is overlaid in the center showing "Share URL (765 bytes)" with a long encoded URL and a blue "Copy URL" button, demonstrating the new share link feature.Screenshot of the same webR REPL interface after the share dialog has been closed. The left panel shows the same R code for the car efficiency analysis, and the right panel displays the identical scatter plot visualization. The console output shows package loading messages and the correlation result (-0.868). This demonstrates the clean interface without the share modal overlay.
