Description

Computes the basic quantities needed for computing the abundance-based multiple-site dissimilarity measuresc and pairwise dissimilarity matrices.

Usage

1

Arguments

x

data frame, where rows are sites and columns are species

Value

The function returns an object of class betapart.abund with the following elements:

multiple.shared.abund

the multiple-site interesection component in terms of abundances (AM)

pair.shared.abund

a matrix containing the agreement in abundance between pairs of sites (A)

min.not.shared.abund

a matrix containing the minimum disagreement in abundance between pairs of sites: min(B,C)

max.not.shared.abund

a matrix containing the maximum disagreement in abundance between pairs of sites between pairs of sites: max(B,C)

pair.not.shared.abund

a matrix containing the total disagreement in abundance between pairs of sites: B+C
