Pleased to share for those using #rstats for analyzing #dyadic data, that we released a major update of dySEM on CRAN (now ver. 1.4.1) *just* before the winter break.
New functionality for scripting/outputting dyadic SEMs, along with (much) more test coverage! 🧵

This approach is especially useful for #sexuality and #gender questions that use choose-all-that-apply options to better reflect people’s lived experiences (particularly in #trans research). I walk through the data-wrangling process with these examples variables!

Started a blog! One of my first posts walks through how to prep your data to use the CATAcode #rpackage (with code + diagrams). With CATAcode, you can easily summarize and visualize responses from choose-all-that-apply questions:

I’ve been thinking about how to find R packages by functionality when you don’t already know the package name.
So over the holidays, Claude Code and I built The Warehouse: a functionality-first R package directory that helps you find packages by what they do.
