armadillo_set_seed: Set the Armadillo Random Number Generator to the given value

In RcppArmadillo: 'Rcpp' Integration for the 'Armadillo' Templated Linear Algebra Library

Set the Armadillo Random Number Generator to the given value

Description

Set the Armadillo Random Number Generator to the given value

Usage

armadillo_set_seed(val)

Arguments

val	The seed used to initialize Armadillo's random number generator.

Details

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.

Value

The function is invoked for its side effect and has no return value.

Note

This has been found to not work as espected in RStudio as its code also uses the system RNG library. You may have to either not run within RStudio or change your code to use a different RNG such as the one from R.
