beta.pair {betapart}  R Documentation 
Incidencebased pairwise dissimilarities
Description
Computes 3 distance matrices accounting for the (i) turnover (replacement), (ii) nestednessresultant component, and (iii) total dissimilarity (i.e. the sum of both components).
Usage
beta.pair(x, index.family = "sorensen")
Arguments
x 
data frame, where rows are sites and columns are species. Alternatively 
index.family 
family of dissimilarity indices, partial match of 
Value
The function returns a list with three dissimilarity matrices.
For index.family="sorensen"
the three matrices are:
beta.sim 

beta.sne 

beta.sor 

For index.family="jaccard"
the three matrices are:
beta.jtu 

beta.jne 

beta.jac
