intern.permu: Internal function

In rauschenberger/globalSeq: Global Test for Counts

Description

The number of permutations of n elements is n!. This function randomly rearranges the elements it times, and then deletes all duplicates. Thus it finds always less than it and n! permutations. If a confounding variable is provided, the function uses stratified permutation. This function is called by the functions omnibus and proprius.

Usage

intern.permu(n, it, group, kind)

Arguments

n	Number of samples.
it	Number of repetitions.
group	Either NULL or a factor of length n.
kind	computation : number between 0 and 1

Value

The function returns a matrix.
