It's difficult for me to evaluate the code quality, since I know C++ well but I don't know the conventions around using the R bindings. But from what I am able to tell the quality seems good. Really impressive for something vibe-coded.

I wrote this almost entirely vibe-coded, I don't even know C++. A slightly scary process, but interesting to see how codex/claude can be both brilliantly fast and competent, and ridiculously stupid and/or dishonest.

There's a companion library just started at https://github.com/hughjonesd/RmlxStats. It's under the GPL. The reason is that codex borrowed a load of code wholesale from base R. Without telling me....
