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).

RcppEnsmallen 0.3.11.0.1 is on CRAN, bringing ensmallen 3.11.0 and two new optimizers: DeltaBarDelta and MomentumDeltaBarDelta. blog.thecoatlessprofessor.com/software-rel... #rstats #rcpp #mlpack

{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

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

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

A well-earned Rousseeuw Prize for the R Core Team, the quietly heroic group behind #rstats, with Brian Ripley speaking for everyone. The stray photo of Excel is an accidental but perfect tribute to where most of us started before we found their work. www.bbc.com/news/article...

A laptop on a wooden desk displaying a Microsoft Excel spreadsheet, densely filled with rows of numerical data and a green toolbar across the top. A person's hand rests on the trackpad, with a tablet, a small potted plant, and a calculator on the desk nearby. The BBC caption beneath reads that the R programming language can be used to analyse data easily, even though the screen is clearly showing Excel rather than R.
