PSA: The long-lived "let us talk about anything and everything" related to #Rcpp mailing list 'rcpp-devel' at R-Forge seems to have moved on to another place where we cannot reach it. May its memory be a blessing. #rstats

I found some weird things when calling both #Rstats and #python libraries for #UMAP using {reticulate}. I *think* it has something to do with how c++ libraries, or whatever numerical libraries are used deep down, are linked but I've reached the limits of my statistical computer science literacy.

Wrote it down for posterity and in case some #Rcpp folks are curious:

🖤 bsvars.org design concept pt. 3 💜

⭐ We use RcppArmadillo for linear algebra because we found it very fast on matrix operations and RNGs, well-documented, easy to use in packages. We 🖤 it! Seriously!

💛 bsvars.org design concept pt. 2 ❤️

⭐ We implemented C++ code using Rcpp and could not be more glad about that! It's a fantastic facility with many functionalities.

✨ And it seems that @eddelbuettel is answering all Rcpp questions the following Canadian morning, which is so great!
