##
Dissimilarity-Based Functions for Ecological Analysis

### Description

Dissimilarity-based analysis functions including ordination and Mantel test functions, intended for use with spatial and community data.

### Details

This package contains well-established dissimilarity-based ecological analyses, such as `nmds`

and `mantel`

, and experimental/research analyses such as `xmantel`

. Helper functions such as `crosstab`

and `cor2m`

facilitate analysis of community data.

Because many of the analyses are time-consuming, this package includes worked examples that can be loaded using `data()`

.
