Compute interspecific distances based on patterns of species co-occurrence in communities.
species.dist(x, metric = c("cij", "jaccard", "checkerboard", "doij"))Community data matrix
Co-occurrence metric to use (see Details section for description)
A dist object with co-occurrences among all species pairs
Currently implemented co-occurrence measures (arguments to metric):
Schoener's index of co-occurrence
Jaccard index of co-occurrence
Checkerboard index of co-occurrence
DOij index of co-occurrence
