randperm

Random Permutation

Generates a random permutation.

randperm(a, k)

`a`	integer or numeric vector of some length `n`.
`k`	integer, smaller as `a` or `length(a)`.

Generates one random permutation of k of the elements a, if a is a vector, or of 1:a if a is a single integer.

Vector of permuted elements of a or 1:a.

This behavior is different from Matlab/Octave, but does better correspond with the behavior of the perms() function.
