Posit::conf(2026) will be in Houston, Sept. 14-16
- announced now at #Positconf2025

#Positconf2026 #Positconf #RStats

The {ragnar} #RStats 📦 has a new function to inspect a data store: ragnar_store_atlas() , which visualizes the store, @t_kalinowski tells #Positconf2025

Several of the projects I mentioned in my #Positconf2025 lightning talk included chatbots. I wrote about creating RAG chatbots in R with the {ragnar} #RStats 📦 here: https://www.infoworld.com/article/4020484/generative-ai-rag-comes-to-the-r-tidyverse.html

One of @Posit 's goals is to "dig through some of that bullshit [about LLMs] so you don't have to" @hadleywickham tells #PositConf2025 in his keynote.
But also: If you can write an #RStats (or Python) function, you can create an LLM tool with ellmer (or chatlas) to extend LLMs in a LOT of ways, he noted.

In development for the {air} #RStats 📦 for R code styling:
# fmt: tabular
to align code creating tabular data
#Positconf2025

@simonpcouch convincing me at #Positconf2025 that I should be automating evaluations of my LLM RAG chatbots with the {vitals} #RStats 📦 instead of doing them manually.

Ryan Johnson at Posit is demoing the Databot Positron extension for data exploration now at #Positconf2025 . If you want more info, I wrote a short article about databot for InfoWorld: https://www.infoworld.com/article/4050900/databot-ai-assisted-data-analysis-in-r-or-python.html

This fall I will have a blind student in my coding class for the first time. Do any other instructors or visually impaired coders have advice beyond making sure my book has useful alt-text for the images? #rstats #accessibility Class book: psyteachr.github.io/reprores-v5/

I found gnuplot (many years ago) to be limited for publication quality plots. The #RStats community is great and helpful, and I'd wager probably bigger than the elisp community. That said, the approach above is language agnostic. You should be able to feed the data table into elisp the same way.

Programming With LLMs #PositConf2025 workshop materials are available on GitHub! 🎉 While going over the materials myself isn't nearly as good as attending the workshop, it's better than nothing. 😀

Wow, setting default labels for your data in #rstats using "label" attributes is a good idea. I'd never heard of this before, but I'm glad that #ggplot2 is now supporting it. Manually specifying axis labels was a bit tedious.

I do like that if you transform the data, the default label is not applied (see the sqrt(body_mass) variable in the first figure here).

What do we gotta do to get negative bracket indexing for ?

I want
penguins[, -"body_mass"]

A quick look at databot, a package in R & Python that aims to act as a data analysis assistant. And now it's also available as an add-in for the Positron IDE.

This looks fun: Use the OpenAI Realtime API in Shiny for a chatbot you can speak to and it speaks back!
{shinyrealtime} #RStats 📦: https://github.com/posit-dev/shinyrealtime/tree/main/pkg-r
Install with remotes::install_github("posit-dev/shinyrealtime/pkg-r")
#GenAI

Ask your data natural-language questions in R or Python with the querychat package! Bonus: You never send that data to an LLM.
