twilight.permute.unpair {twilight} | R Documentation

## Permutation matrix of unpaired class labels

### Description

The function returns a matrix where each row is a (un)balanced permutation of the input twosample class labels.

### Usage

    twilight.permute.unpair(v, m, bal = TRUE)

### Arguments

`v` | A binary vector representing class labels in original order.
`m` | A numerical value giving the number of permutations.
`bal` | Logical value. Results in balanced or unbalanced permutations.

### Value

Returns a matrix where each row contains one permuted vector of class labels. Note that even for balanced permutations, the first row always contains the original vector.
