Helper Function to Set and Save the RNG Seed

This code is basically copied from stats:::simulate.lm.

Usage

set_seed(seed = NULL)

Arguments

seed

an object specifying if and how the random number generator should be initialized ("seeded"). Either NULL (default) or an integer that will be used in a call to set.seed() before simulating the response vectors. If set, the value is saved as the seed slot of the returned object. The default, NULL will not change the random generator state.

Value

The integer vector containing the random number generate state will be returned, in order to call this function with this input to reproduce the obtained simulation results.
