distanceHadamard {phangorn} | R Documentation

## Distance Hadamard

### Description

Distance Hadamard produces spectra of splits from a distance matrix.

### Usage

    distanceHadamard(dm, eps = 0.001)

### Arguments

`dm` | A distance matrix.
`eps` | Threshold value for splits.

### Value

`distanceHadamard` returns a matrix. The first column contains the distance spectra, the second one the edge-spectra. If eps is positive an object of with all splits greater eps is returned.
