beta.temp {betapart}  R Documentation 
Temporal change in community composition
Description
Computes the dissimilarity for each locality between time 1 and time 2, considering the turnover and nestedness components of temporal change, and the sum of both values (overall change)
Usage
beta.temp(x, y, index.family="sorensen")
Arguments
x 
data frame for time 1, where rows are sites and columns are species 
y 
data frame for time 2, where rows are sites and columns are species.

index.family 
family of dissimilarity indices, partial match of 
Value
The function returns a data frame where rows are sites and columns are pairwise dissimilarity
values between cell composition in time 1 and time 2. For index.family="sorensen"
the indices are
beta.sim, beta.sne, and beta.sor. For index.family="jaccard"
the indices are beta.jtu, beta.sne, and beta.jac.
