PSA We can have fast(er) #Rstats continuous integration via #r2u at #codeberg. Thanks to @zeileis.org for the recent question, Doug Kelkhoff for the initial nudge, and @coatless.bsky.social for sorting details out. You can use both forgejo actions and woodpecker. See codeberg.org/eddelbuettel...

On iPad: File, Code, Run and View menus (hold Command to see them), plus Projects and History in the four-pane view. Everywhere: VoiceOver reads results and errors aloud, and the app respects larger text, reduced motion and higher contrast.

blog.thecoatlessprofessor.comwebRios 1.2.0 Now Available on the App Store – TheCoatlessProfessorwebRios 1.2.0, an R editor for iPhone and iPad that uses webR, moves to R 4.6.0 and adds a Stop button, interactive plots, and web requests through a proxy on the device.

One heads-up: R 4.6 means your packages need reinstalling once. The app offers to do it in one tap. Your devices must be on iOS/iPadOS 26 or later. The full story, with pictures: blog.thecoatlessprofessor.com/posts/webrio... App Store: apps.apple.com/app/id675807...

Big tables open quickly and you can filter, sort and search them. The package list tells you what each package does, and your saved packages load several times faster.

R can reach the web now. Fetch live data with httr2 and chart it with ggplot2, right on your phone. By default that traffic goes through a small helper running on your own device, not through anyone else's server.

Charts you can touch. Interactive plots now open in the app, so you can tap, zoom and pan. Plots you pin stay pinned, even after you close the app.

Got an R script in your email? It opens straight into webRios now, from Mail, Files and other apps. CSV files too. The editor also stays quick on long scripts, with text sizes up to 30 pt.

The big one: a Stop button. Started a loop that never ends? Tap Stop, or press Command-period on a keyboard, and R stops right where it is. Your variables stay put. The old advice, "restart the app", is officially retired.

Plots can show up right in the Console now, under the code that drew them. Fit a model, plot it, and the chart sits beside the numbers.

{surreal} 0.0.3 is on CRAN, just in time for jack-o'-lantern season, my favorite time to use this trick back when I was teaching. It hides a picture in a dataset, and the residual plot of a linear model brings it back. YT: youtu.be/JJtKLPDNoMo blog.thecoatlessprofessor.com/software-rel... #rstats

webRios 1.2.0 is off to the App Store for review! It's an R editor for iPhone and iPad, built on webR. Now with: R 4.6, a Stop button for runaway loops, plotly and leaflet widgets, and httr2 on the device. Fashionably late to the party, but on its way. webrios.caffeinatedmath.com

webrarian is a new R package. It turns a folder of R scripts and data into a static website where R runs in the visitor's browser, with no compute server and nothing to install. blog.thecoatlessprofessor.com/posts/introd... #rstats #webr #webassembly

No compute server sits behind the site. A static host hands out the files and the reader's browser does the computing, so GitHub Pages, Netlify, Cloudflare Pages or your own web server can publish it.

coatless-wasm.github.iowebrarianBuild websites where R runs in the browser, with your packages and files in place

webrarian runs on webR, the WebAssembly distribution of R, by the webR team. Version 0.1.0 is on GitHub. pak::pak("coatless-wasm/webrarian") Guides and reference coatless-wasm.github.io/webrarian/ Source github.com/coatless-was...

Five steps take a folder to a site. catalog() starts a collection, acquire_package() and acquire_file() fill it, bind() builds the site, reading_room() previews it, and circulate_via_github() sets up publishing on GitHub Pages. Watch it in 100 seconds. youtu.be/Ujoa-zBFKpY

The page is a small workspace, with an editor, an R console, your files and your plots. Visitors run your script, change it, and share their version as a link. Their edits stay in their own browser. There is a live demo to try. coatless-wasm.github.io/webrarian/de...

webRoid 1.1.1 is on Google Play. The app that runs R on your Android phone or tablet moves up to R 4.6.0, and its charts are now the kind you’re allowed to poke. App: play.google.com/store/apps/d... Docs: webroid.caffeinatedmath.com #rstats #webr #android #webassembly

webRoid also now allows you to request a "Copy Files Back from R" to sync files to your folders. Plus, you can now tap an excel file opens Import Dataset, which reads Excel once readxl is installed.

Lastly, for the tablet users out there, we've greatly improved the classic four-pane Workspace layout. If you haven't yet, try out webRoid on your Android 15 or later Phone or Tablet! Google Play: play.google.com/store/apps/d... Release write-up: blog.thecoatlessprofessor.com/posts/webroi...

One heads-up before you update... The new R version can’t load R packages installed by the old one. So, the app clears them the first time it opens. A notice lists them, and one tap on Reinstall brings back each one the webR repository has. R on PC requires the same when going from 4.5 to 4.6.

Starting in webRoid v1.1.1, you can restart R instead of restarting the app! After a minute, a banner says R is still working and offers a fresh session. Your variables in the current session will go away though and need to be redefined!

{Pyodios} v1.1.0 has been sent over to the App Store for approval. It includes a host of fixes, features, and a bump from Python v3.13 to v3.14. This requires iOS 26 or above. Once approved, we'll be pulling back the initial Pyodios v1.0.0 version to avoid it being available on iOS 17/18 devices.

Five runtime strategies, both languages: offline shinylive (WebR/Pyodide), a bundled interpreter, the system install, auto-download on first launch, or a container. Several apps can share one launcher. Full tour: blog.thecoatlessprofessor.com/posts/reintr...

Every R course has the whiteboard moment where you draw a vector as a row of boxes. {paintr} draws it and writes the accessor in each cell, so the diagram and the code are one object. Now on CRAN. #rstats blog.thecoatlessprofessor.com/software-rel...

Every painter has a gpaint_*() twin that returns a real ggplot, so it works with ggsave() and patchwork() like other ggplot2 extension packages. Thus, you get the same drawing either way, in four palettes.

And everything in one place... CRAN: cran.r-project.org/package=paintr Source: github.com/coatless-rpk... Release notes/Blog: blog.thecoatlessprofessor.com/software-rel...

show_indices = 'cell' stamps every matrix cell with the [row, column] that reaches it. Useful when the thing you are explaining is not the values but the addressing.

Formatting further aims to emphasize magnitude by showing significant figures, but the digits it drops go grey rather than vanishing, so 123456.789 still reads as a bold 123 with a faded 457 with decimals rounded if its a large number. NA is red. Inf is blue.

@martynplummer.bsky.social

You already know a data frame is a list whose elements happen to share a length. Your students do not. paint_list() and paint_data_frame() draw the same card until one element changes length and the bottom edge goes ragged. That is the lesson, drawn.

It’s the end of an era: we are sunsetting rpubs.com, quartopub.com, and shinyapps.io in favour of connect.posit.cloud. These services are important, but we need to focus our efforts on a single platform (and it’s overall less confusing to have one place to publish everything you do in R or Python).
