πŸ–€ bsvars.org design concept pt. 3 πŸ’œ

⭐ 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 πŸ–€ it! Seriously!

🌐 bsvars.org/

#bsvars.org #bsvars #bsvarSIGNs #Rcpp #RcppArmadillo #rstats

bsvars.org design concept: Our packages use ReppArmadillo for linear algebra
frontier package for linear algebra linking R with C++ library Armadillo; implements fast random number generators; makes C++ code as expressive as R's (or MATLAB's). we love it!

πŸ’› 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!

🌐 bsvars.org/

#bsvars.org #bsvars #bsvarSIGNs #Rcpp #rstats

Our packages rely on C++ code implemented using Rcpp: simple package development; simple setup, compilation, linking, object compatibility with R; parallel computations via openMP; super fast on loops; great community support.

What if you could just wave a magic wand over your R #rstats :rstats: code and have it transform into something that ran as fast as or faster than C? @t_kalinowski's {quickr} 'R to Fortran Transpiler' does that for you! #fortran

With bonus comparisons to #Rcpp #julialang :julia: and #rustlang :rust:

Updated to restrict to integers thanks to @toddixd

Just noticed that now tops 100 million downloads per the (known downward-biased subset of CRAN mirrors served via the CDN set up by posit and excluding all other mirrors).
