beta.pair.abund {betapart}  R Documentation 
Computes 3 distance matrices accounting for the (i) balanced variation in abundances, (ii) abundance gradients, and (iii) total dissimilarity (i.e. the sum of both components).
beta.pair.abund(x, index.family = "bray")
x 
data frame, where rows are sites and columns are species. Alternatively 
index.family 
family of dissimilarity indices, partial match of 
The function returns a list with three dissimilarity matrices.
For index.family="bray"
the three matrices are:
beta.bray.bal 

beta.bray.gra 

beta.bray 

For index.family="ruzicka"
the three matrices are:
beta.ruz.bal 

beta.ruz.gra 

beta.ruz
