multCh7 {NSM3}

Possible arrangements by row for a matrix

Description

Similar to multComb, this function will generate all of the possible arrangements of the data by row within a matrix. For a given matrix of n rows and k columns, this will give (k!)^n possible arrangements

Usage

multCh7(our.matrix)

Arguments

our.matrix

The matrix containing the data which will be rearranged by row.

Details

The computations involved get very time consuming very quickly, so be careful not to use it for too large of a matrix.

Value

Returns an array, containing (k!)^n distinct matrices of the same size as our.matrix

Note

This function is used to generate the possible permutations for the Exact methods used in Chapter 7 of Hollander, Wolfe, and Chicken - Nonparametric Statistical Methods Third Edition.
