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

If you'd like to contribute to the tidyverse or tidymodels packages -- or learn how to -- join us at the tidyverse developer day! There are some tickets left for underrepresented minorities. #RStats #RLadies More info in the blog post: www.tidyverse.org/blog/2025/07...

I'll be talking about Quarto at PyData in September. Focus will be on how Quarto can be used to get your Notebooks Analysis to the world easily, and under different forms. Don't hesitate to share anything you would like me to tackle, and if it relates I am happy to ! And maybe see you there !

We still have spots available for tidyverse dev day on Sept 19: www.tidyverse.org/blog/2025/07.... Please come along to contribute to the tidyverse and have a bunch of fun along the way! It's open to all, but is most convenient if you're coming to posit::conf or live near Atlanta #rstats

It's always a pleasure to present at useR, and I'm doing so virtually this year. Hit the following video to see how we've been upgrading async across the ecosystem at Posit, whether that's in #RShiny, the #tidyverse or our LLM tooling. #Rstats #user2025 youtu.be/sGLD8oVquho?...

#rstats polars 1.0.0 is now available! polars provides bindings to the eponymous Rust library, a very efficient dataframe library. This is the outcome of a 1-year long rewrite led by @eitsupi to refactor the internals and match the API of Python polars. pola-rs.github.io/r-polars/ Details ⬇️

We're happy to announce that there will be another #rstats Tidy Development Day after the 2025 posit::conf in Atlanta! www.tidyverse.org/blog/2025/07...

mcptools, a package implementing the Model Context Protocol in #rstats, is now on CRAN!🌉 We see significant opportunity with MCP and, at the same time, want to note that it's still a nascent ecosystem with serious security risks. www.tidyverse.org/blog/2025/07...

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.

Bleeding edge update for the #tidyverse purrr package with even more seamless #rstats parallel maps. Introducing our shiniest new adverb: `in_parallel()`. Just wrap your function to take advantage of blazing fast parallel processing via mirai. pak::pak("tidyverse/purrr") purrr.tidyverse.org/dev/

Happy 18th birthday ggplot2! #rstats

For those following the #rstats {ellmer} package: I got the chat_databricks() and chat_snowflake() providers working with tool calling this past week. IMHO this means these providers are no longer toys: they can be used with RAG (via {ragnar}) and other complex tasks like @simonpcouch.com's {btw}.

We are delighted to announce mirai 2.3.0 for advanced async computing in #RStats! Mirai allows event-driven async in Shiny & parallel processing in purrr. This release brings improvements in serialization & distributed computing. Read more from @shikokuchuo.net: shikokuchuo.net/posts/26-mir...

#rstats WHAT MAGICKS IS THIS?!?!?! https://github.com/t-kalinowski/quickr

Want to easily use LLMs from R? ellmer 0.2.0 provides: • Batch & parallel processing • A universal parameter interface • Cost tracking • Support for Mistral, Hugging Face, & Portkey And much more! Read all about it at: www.tidyverse.org/blog/2025/05... #rstats

We're super focused on bringing the latest capabilities to the #Rstats open source community. The acquaint MCP server uses the same event-driven async and modern communications layer as mirai.r-lib.org.

Here's the full chat transcript, for those interested: claude.ai/share/7dc9e2... Many thanks to @shikokuchuo.net and @winstonchang.bsky.social for helping bring this to life.

Introducing acquaint, an R package that turns your R sessions into a Model Context Protocol (MCP) server. This allows MCP-enabled tools like Claude Desktop and Claude Code to run #rstats code _in your active R sessions_ to explore objects, read documentation, etc. posit-dev.github.io/acquaint/

mirai - minimalist async framework for #RStats - released as an 'r-lib' package. Blog post: Advancing Async Computing in R. shikokuchuo.net/posts/26-mir... mirai provides event-driven async for #RShiny and parallel processing for purrr #tidyverse. Really excited to be working on this at Posit!

Announcing the release of nanonext 1.6.0, the first as an 'r-lib' package! #rstats This is the concurrency toolkit that underpins mirai (mirai.r-lib.org) and other R packages requiring state of the art communications, with next-level performance and scalability. nanonext.r-lib.org

I'll be there giving a lightning talk on building {geotargets} with @njtierney.bsky.social. If you can't join in person, it's been a really excellent virtual experience in the past. They have professional camera operators and multiple camera angles. It is nothing like a virtual academic conference.

In the last 6 weeks I've written two Python packages. But I developed them in RStudio IDE with a .Rproj and usethis

I’m pleased to announce that R now has a robust native method of retrieving IP addresses on all network interfaces. Especially useful if connected to multiple networks, incl. VPNs etc.
