This came across my radar. AI for RStudio? #rstats

Hello #rstats, I'm searching for work opportunities and wanted to put out a friendly inquiry. My work has focused on shiny and package development, github.com/nteetor/. I would appreciate any advice or leads and I am happy to talk more. Thank you!

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.

I cannot fully reveal my confidential strategy for investing in the Trump era, but the first half is "Buy low".

It was a cold day in America. And more is coming. Let's be ready.

Recycling is the opiate of the middle class. #plastic #pollution

Yes! It took me 6 months to figure out, okay, now what? But when I did it was great.

The R Cookbook is available on-line. It contains useful recipes, oriented towards beginners. #rstats

Wait a minute. Over Christmas holiday, people had something better to do?

Gotta say, the {ellmer} package is robust and pretty darn easy to use. Nicely done, Dr. Wickham!

ellmer (formerly known as elmer) is now on CRAN! ellmer makes it easy to chat with LLM models from a variety of providers and includes support for streaming responses, tool calling and structured data extraction: ellmer.tidyverse.org #rstats

@matloff.bsky.social @datavisfriendly.bsky.social I have a "small-ish n" problem, the covariance of short-ish time series. The EWMA cov estimate worked pretty well, but the matrix was not invertible ("uncooperative"). The cov.shrink function gave an invertible matrix; and the shrinkage was a bonus.

OMG. @eddelbuettel.com points out that the correct spelling of the function is `cov.shrink`. Thank you, Dirk! #mybad

Yes! Thank you, Norm.

Are you an #rstats person struggling with an uncooperative covariance matrix? I was. I tried the `cov.shink` function of the {corpcor} package and got a very noticeable improvement in my models. Recommended. #positive #definite

You are in very good company, my friend. You are not alone. Be brave. #zzzzz

Thank you! Your comments and code example are very useful. This whole S7 thing is looking quite good. Time to get my hands dirty.

Thank you. That is quite helpful, actually. Seeing someone work thru their use-case is great.

On paper, the new S7 tools for object-oriented programming in #rstats sound great. Can anyone comment on their experience using S7? I haven't seen any discussion about it. I use R6 often, and S7 looks even better. (And, BTW, many thanks to @hadley.nz for spearheading the S7 project!)
