Generates all permutations of a vector a.
perms(a)
a |
numeric vector of some length |
If a is a vector of length n, generate all permutations
of the elements in a as a matrix of size n! x n where
each row represents one permutation.
A matrix will be expanded as vector.
matrix of permutations of the elements of a
Not feasible for length(a) > 10.
