part.m.tree: Partition of multi-sample dissimilarity indices using...

In CommEcol: Community Ecology Analyses

Partition of multi-sample dissimilarity indices using phylogenetic/functional data

Description

This function computes the partition of multi-sample Sorensen and Jaccard dissimilarity indices described by Baselga (2012), but adapted for phylogenetic/functional data. The two resulting components are dissimilarities due to turnover and nestednes.

Usage

part.m.tree(comm, tree, index.family="sorensen")

Arguments

comm	Dataframe or matrix with samples in rows and species in columns.
tree	A phylogenetic/functional tree containing all species listed in comm

.

index.family

The family of dissimilarity indices to be partitionated. Partial match to "sorensen" or "jaccard".

Value

A list including the number of samples and three dissimilarity values. The nomenclature of the dissimilarities follows Baselga (2012). For the jaccard:

JAC	Multi-sample Jaccard dissimilarity index.
JTU	The turnover component of the Jaccard index.
JNE	The nestedness component of the Jaccard index.

For the sorensen:

SOR	Multi-sample Sorensen dissimilarity index.
SIM	The turnover component of the Sorensen index (Simpson index).
SNE	The nestedness component of the Sorensen index.
