Getting the hang of this {Rcpp} stuff. This makes porting some legacy C++ code easy. I've done interfacing with Fortran in the past but having the wrappers auto generate makes my life easy. I'm sure I'll hit roadblocks, but I'm curious how far I can push things.

Kudos to @eddelbuettel et al.

Nice!

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!

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!

What if you could just wave a magic wand over your R #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 and #rustlang

Updated to restrict to integers thanks to @toddixd

Just noticed that #Rcpp 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).

It was so so good to work with Monash Uni students on their first steps in C++ programming for R applications! They made it! And now, they're ready to code!
