Arguments

site_species

a data.frame with sites in rows and species in columns. NOTE: the first column should be named "site" and indicate site names. The other columns should be named according to species names.

Value

A three-column data.frame with:

• species: the name of the species;

• n_sites: the number of sites where the species is present;

• coverage: the percentage of sites where the species is present.
