In nptest: Nonparametric Bootstrap and Permutation Tests

Generate All Permutations of n Elements

Description

Generates all n! vectors of length n consisting of permutations of the integers 1 to n.

Usage

permn(n)

Arguments

n	Number of elements.

Details

Adapted from the "permutations" function in the e1071 R package.

Value

Matrix of dimension n by n! where each column contains a unique permutation vector.

Warning

For large n this function will consume a lot of memory and may even crash R.

Note

Used for exact tests in np.cor.test and np.reg.test.
