Generate all permutations of x taken \(m\) at a time. If argument FUN is not NULL, applies a function given by the argument to each permutation.
permut(x, m=length(x), FUN=NULL,...)vector source for permutations.
number of elements to choose. Default is m=length(x).
function to be applied to each permutation; default NULL means the identity, i.e., to return the permutation.
optionally, further arguments to FUN.
A matrix with one permutation, or the value returned by FUN, in each line.
Based on function permutations from package gtools. This function is required for the computation of the exact p-value of some randomness tests.
