I demonstrated OpenTelemetry at Japan.R 2025 last week as an example of ecosystem-wide innovation we're driving at Posit for #rstats. Now thanks to @schloerke.com we have it in a release version of Shiny. This was also a technology that other community speakers picked as one to watch in 2026!

I'm honoured and delighted to be delivering the keynote for Japan.R 2025 in Tokyo on Dec 6. New ideas on creativity and community in open source software. Live demonstrations of ggbot2, OpenTelemetry and mirai (Posit ecosystem-wide initiatives). #Rstats #Tidyverse japanr.connpass.com/event/374714/

Everyone can now view my posit::conf 2025 talk "purrrfectly parallel, purrrfectly distributed"! {purrr} now lets you access the magic of {mirai} directly, as the modern way to make things faster through parallel computation in #rstats. youtu.be/j1yHjMvbnQM?...

Much thanks to @lionelhenry.bsky.social and @cirw.in for pushing the rust bindings for Jupyter further and making @posit.co's Ark runtime work in @zed.dev! github.com/zed-industri...

To be effective, data science agents need to be able to read plots reliably. @sara-altman.bsky.social and I wrote about some concerning findings on LLMs' ability to interpret plots when the content contradicts their expectations on the @posit.co blog. posit.co/blog/introdu...

I put out a patch release of mirai today. Version 2.5.2 really improves the OpenTelemetry integration so you can more easily see into your async workflows. Other key ecosystem packages will roll out with this enabled - next up: Shiny! mirai.r-lib.org #Rstats

purrr 1.2.0 out now — mostly removing long deprecated functions but a few small performance nad parallel processing improvements. Learn more at www.tidyverse.org/blog/2025/11... #rstats

mcptools 0.2.0 is on CRAN! mcptools implements the Model Context Protocol in #rstats, allowing ellmer users to share context and tools more easily between LLM applications. Read more: github.com/posit-dev/mc...

reticulate v1.44 is on CRAN! Positron integration is now enabled by default. Enjoy R and Python REPL consoles powered by concurrent threads in the same process, zero‑copy R↔Python data transfer, and full Variables Pane support. Full changelog: github.com/rstudio/reti... #rstats #python #pydata

I'm excited to share a new version of the Air formatter for #rstats, with support for tabular formatting! Super useful with `tibble::tribble()` calls or `data.table::fcase()`. It's currently experimental as we're looking to get feedback on the feature, so please let us know what you think.

Gave a talk about orbital last week at Socal RUG, it was delightful as always to spend time with these people. Slides: emilhvitfeldt.github.io/talk-orbital... Recording: www.youtube.com/live/pm-Ve3w...

I'll be keynoting at R/Pharma in a few weeks! The conference is free and virtual; all are welcome to join. My talk "Practical AI for data science" is on November 5th and should be broadly accessible for #rstats users, regardless of industry. :) Learn more & register: rinpharma.com

I recently added a Deepwiki badge to mirai.r-lib.org. Not because I think the current documentation is lacking 😅, but it takes you to an `Ask DeepWiki` prompt with the full mirai source code as context so you can ask questions (and get answers) in *any* language. Any feedback welcome! #rstats

I wrote a paper about "Examining the Interface Design of Tidyverse" 📝 TL;DR to follow in future 😊 arxiv.org/abs/2510.10382

Thanks to @paleolimbot.bsky.social's great work, the sedonadb R package is now also available to Windows via R-universe 🎉 I'm excited particularly because I believe sedonadb is the easiest tool for R users to access GeoParquet data. #rstats apache.r-universe.dev/sedonadb

Seriously cool stuff from @shikokuchuo.net on mirai+ellmer+shiny+httr2 with otel for telemetry at Shiny in Production! You can use it to improve the performance of your Shiny apps by getting really granular information about it what's going on! #rstats

mirai 2.5.1 released. mirai.r-lib.org This is a patch release, but brings a new synchronous mode: `daemons(sync = TRUE)` runs your code in the same process. This means you can now drop into a browser session *within* your mirai #rstats code! p.s. amazing hex stickers made by someone @posit.co!!

Take your plots from drab to fab! #ggplot2

Posit::conf(2025) "Purrrfectly parallel, purrrfectly distributed" The slides from the talk are available at: shikokuchuo-posit2025.share.connect.posit.cloud See why we now have parallel purrr, powered by mirai, and how to use it to distribute compute to other machines. #positconf2025 #tidyverse

Can't wait to see everyone at posit::conf(2025)!! Here's my annual "things to do" list for food, coffee, bakeries, and bars near conf! #positconf2025 #rstats docs.google.com/document/d/1...

I'm hoping you'll join our session on Strengthening the R Ecosystem at posit::conf(2025) on the Thursday morning! Find out about the hottest new thing in the tidyverse: "purrrfectly parallel, purrrfectly distributed" (yes, it's something about cats). #rstats #tidyverse #PositConf2025 pos.it/conf

{otel} + #rstats is becoming a crazy partnership. This project has driven me to use/write {promises} in ways that makes my 🧠 ache 😅. The reward is worth it! See you at #PositConf2025 where I'll talk about this in more detail

I feel like the {targets} + {shiny} combo doesn’t get much #rstats airtime - I dunno maybe it’s so obvious that everyone is just doing it? You build your app data with targets and then tar_read / tar_load it out of the targets store into shiny app env on app start.
