beta_core: Taxonomic (non-phylogenetic) beta diversity

Description

Data are assumed to be presence / absence (0 / 1) and all values greater zero are assumed to reflect presence.

Usage

beta_core(x)
beta_diss(x, index.family = "sorensen")

Arguments

x

an object of class Matrix, where rows are sites and columns are species.

index.family

family of dissimilarity indices, partial match of "sorensen" or "jaccard".

Value

beta_core returns an object of class beta_diss like the betapart.core function. This object can be called by beta.pair or beta.multi.

beta_diss returns a list with three dissimilarity matrices. See beta.pair for details.

Details

beta_core is helper function to compute the basic quantities needed for computing the "sorensen" or "jaccard" index.
