Description
Note: Before the calculation, species (rows) with only zero occurrences are removed from m.
Usage
1
Arguments
m
Community data matrix with species as rows and sites as columns. Can
contain either incidences (1/0) or abundances (natural numbers).
clean
Logical. Do you want to remove zero-sum rows or columns? When the index needs
the "d" fraction (sites where no species occurs), only zero-sum rows are removed.
Value
A dist object with the pairwise association values.
