beta.temp: 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.
x and y must contain exactly the same sites and species
index.family
family of dissimilarity indices, partial match of "sorensen" or "jaccard".
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.
