Set the Armadillo Random Number Generator to a random value
armadillo_set_seed_random()
The function is invoked for its side effect and has no return value.
Depending on whether RcppArmadillo was compiled for the C++98 standard
(currently the default) or for C++11 (optional), two different RNGs may be used.
This function resets either. For C++98, the R programming language's RNG is used.
For C++11, the RNG included in the <random>
library is used only when
#define ARMA_USE_CXX11_RNG
is placed before #include <RcppArmadillo.h>
.
Otherwise, the R programming language's RNG will be used.
The R documentation on its RNGs all of which are accessible via Rcpp.
