permute: Permute a vector.

Description

Permute the values contained in a vector.

Usage

permute(x)

Arguments

x

The vector of values that are to be permuted.

Value

A matrix in which each row is a permutation of the values in x.

Details

permute calculates the number of permutations and creates a matrix with that number of rows. It fills the first column with the elements of x in groups large enough to cover the permutations of a vector with one less value. It then fills the remaining columns by calling itself with all values except the one in the first row of the current block. If x has only two values, it returns the trivial permutation of x and its reverse.
