species.dist: Species co-occurrence distances

In picante: Integrating Phylogenies and Ecology

Description

Compute interspecific distances based on patterns of species co-occurrence in communities.

Usage

species.dist(x, metric = c("cij", "jaccard", "checkerboard", "doij"))

Arguments

x	Community data matrix
metric	Co-occurrence metric to use (see Details section for description)

Details

Currently implemented co-occurrence measures (arguments to metric):

cij

Schoener's index of co-occurrence

jaccard

Jaccard index of co-occurrence

checkerboard

Checkerboard index of co-occurrence

doij

DOij index of co-occurrence

Value

A dist object with co-occurrences among all species pairs
