Hi Youssef,

Rcpp has sugar for the R random number generators. This is nice if you want
to let your users set the random seed in R code outside of the package for
reproducibility: http://gallery.rcpp.org/articles/random-number-generation/

Alternatively, if you enable C++11, there are some random number generators
in std: https://www.guyrutenberg.com/2014/05/03/c-mt19937-example/
