twPERM {ppiStats} | R Documentation

## A function to compute a permutation test on a two way table.h

### Description

This function takes the entries of a two-way table and creates two binary logical vectors upon which it computes a permutation test to check for independence.

### Usage

    twowayPERM( v1, v2, NPERM, stat, seed = 123)
    makeBinVect(n11, n12, n21, n22)

### Arguments

`v1` | A logical vector.
`v2` | A logical vector the same length as v1.
`NPERM` | A positive integer. The number of tests to be conducted.
`stat` | A statistical function passed into to test the permutation on two vectors.
`seed` | A positive integer. To set the seed for the random number generator.
`n11` | A postive integer. The value of (1,1) in the two way table.
`n12` | A postive integer. The value of (1,2) in the two way table.
`n21` | A postive integer. The value of (2,1) in the two way table.
`n22` | A postive integer. The value of (2,2) in the two way table.

### Value

A numeric vector containing the p-values for the test that the permutation of the vector v1 is independent from v2.
