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

armadillo_set_seed {RcppArmadillo} | R Documentation

## 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 system library RNG is used. It may have poor performance, particularly on older versions of Windows. For C++11, the RNG included in its library is 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.
