randtest.amova {ade4} | R Documentation

## Permutation tests on an analysis of molecular variance (in C).

### Description

Tests the components of covariance with permutation processes described by Excoffier et al. (1992).

### Usage

### Arguments

`xtest` | an object of class `amova`
`nrepet` | the number of permutations
