comdist: Calculates inter-community mean pairwise distance
Description
Calculates MPD (mean pairwise distance) separating taxa in two communities, a measure of phylogenetic beta diversity
Usage
comdist(comm, dis, abundance.weighted = FALSE)
Value
Distance object of MPD values separating each pair of communities.
Arguments
comm
Community data matrix
dis
Interspecific distance matrix
abundance.weighted
Should mean pairwise distances separating species in two communities be weighted by species abundances? (default = FALSE)
