Now on CRAN: {livelink}. Hand it a string, a file path, or your clipboard and get back a URL that opens a live R session in the browser, code already loaded. CRAN: cran.r-project.org/web/packages... Release notes: blog.thecoatlessprofessor.com/software-rel... #rstats

Three-panel diagram showing how livelink works. Panel 1, "You write R": a code block wrapping a short script in webr_repl_link(), where the script loads the mtcars dataset and plots mpg against weight with steelblue points. A caption notes that a string, a file path, or the clipboard work too. Panel 2, "You get a URL": a long webr.r-wasm.org link with the code encoded in the fragment. Panel 3, "They get a live R session": a browser window with four panes, an editor holding script.R, a file browser showing home/web_user/script.R, a terminal where source('script.R') and mean(mtcars$mpg) return 20.09062, and a pane displaying the resulting scatter plot.

What about the forthcoming quarto-hub.com that's moving into Release Candidate (RC) status for Quarto v2? c.f. bsky.app/profile/coat... github.com/quarto-dev/q...

quarto-hub: track invitations centrally · Issue #344 · quarto-dev/q2

"User X shares project Y with user Z" is a thing we could track in the same service that will track (user_id, project_set_automerge_id) tuples.

github.com

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).

{livelink} will also soon be expanded over to Python just after Pyodidarian launches as the later comes with a Pyodide powered Python enhanced 4-panel editor based off of webR's. #pyodide #livelink #python

Screenshot of the Pyodide REPL, a browser-based Python environment. The left pane shows example code using pandas and matplotlib; the right pane shows an Environment panel of variables and a Plots tab with a line chart titled "n squared."

#webR and #Shinylive already share browser-runnable links from their editors. livelink is a small #Rstats wrapper around that idea: build those links from R (scripts & projects) and decode any of them back into files. GH github.com/coatless-rpk... Post blog.thecoatlessprofessor.com/programming/...

A split comparison of two ways to share an R project. The top path, 'send the instructions,' runs through install steps to a laptop marked 'runs, if it installs.' The bottom path, 'send a link,' goes straight to a browser already running the plot.

A loop showing encode and decode as inverse steps. Three project files flow along webr_repl_project() into a single URL, then back along decode_webr_link() into the same three files.

Last week I gave a quick overview on R Observatory. Here's the longer write-up of what it does. blog.thecoatlessprofessor.com/posts/beginn... #rstats

The Beginnings of the R Observatory – TheCoatlessProfessor

blog.thecoatlessprofessor.com

Checking on an R package usually takes five open tabs: CRAN, GitHub, download counts, reverse deps, check results. R Observatory collects all of that on one page, for every CRAN and Bioconductor package. r-observatory.thecoatlessprofessor.com #rstats

The ggplot2 package page on R Observatory. A header gives the name, version 4.0.3, and tagline, with four headline numbers: 6,665 packages depend on it, 26.4M downloads a year, 81.1% test coverage, and 13 of 13 CRAN checks passing. Sections below cover an Overview (maintainer, first-published date, description), install commands in tabs (CRAN, pak, Ubuntu r2u, Fedora COPR, openSUSE OBS), Health (CRAN check result, code-health facts, and a dated check history), and the start of Downloads. A Vital Signs sidebar summarizes health, coverage, docs, downloads, reverse dependencies (6,665 direct and 1,909 indirect), release, license, and links to reference docs.

Bees knees that #JupyterLite picked up URL share encoding. But, for those more interested in Terminal emulation in #WASM environments, the cherry ontop is Jupyterlite-Terminal package w/ bash + vim and nano editors. May be the start of a fun new weekend project github.com/jupyterlite/... #pyodide

Yes, yes it was a #quarto playground I spied back in the day. Confirmed by @shikokuchuo.net 's #user2026 talk. Quarto levels up via: quarto-hub.com

Screenshot of Charlie's talk posted on Linkedin showing the playground and it's home over at quarto-hub.com

Looks like #quarto v2 will usher in new webassembly playground based on a scene grab from Posit’s in office post

Turn a Shiny app into a desktop app your users just double-click. shinyelectron wraps #rstats or #Python Shiny in Electron and builds a native installer for macOS, Windows, and Linux, with a runtime of your choice (including a fully offline build). Build locally or in CI. #rshiny #pyshiny

73/76. The desktop is coming for your Shiny apps. Or your Shiny apps are coming for the desktop. Hard to tell from in here. Either way, the machines have been at it for an hour and they're almost done. #rshiny #pyshiny #rstats #python

A GitHub Actions workflow run for the coatless-rpkg/shinyelectron repository, titled "shinyelectron 0.2.0 #22" under the "Build demo installers" workflow. Status reads "In progress," triggered via a release one hour ago when user coatless published v0.2.0. The build-demos.yml workflow shows a completed "setup" job (59 seconds) connected to a "Matrix: build" stage reading "73/76 jobs completed." A left sidebar lists individual jobs for demo-py-app-suite across multiple platforms, including auto-download builds for linux-x64, mac-arm64, mac-x64, and win-x64, plus a bundled linux-x64 build, each marked with a green checkmark.

Apparently I shipped Mac versions of my iPhone/iPad apps by leaving a checkbox on. Pyodios #python and webRios #rstats run on macOS now. #WebAssembly really does go anywhere. TIL.

A Mac screen split between two windows. On the left, the Mac App Store shows an account page with Pyodios (displaying a download button) and webRios (with an Open button), both marked "Designed for iPad. Not verified for macOS." On the right, the webRios app is open to a "Welcome to webRios" onboarding screen reading "Run R on your iOS device," explaining that webRios brings R statistical computing to iPhone and iPad through webR, a WebAssembly distribution of R. A sidebar lists Console, Editor, Plots, Environment, File Browser, Projects, Packages, History, R Help, and Settings.

@posit.co any chance #P3M download stats could be published like cran-logs.rstudio.com? cran-logs only logs CRAN-mirror source pulls, so the Linux binaries P3M serves (CI, Docker, etc.) are invisible to authors. The API has a downloads field but returns count: 0. #rstats
