Given a distance (or dissimilarity) matrix or dist() objects compute
regional/global level distinctiveness as if all species were present in the
same community.
distinctiveness_global(dist_obj, di_name = "global_di")a data.frame with two columns: by default species that contains the
species names and global_di that contains the distinctiveness values.
The first column that contains species names can renamed based on dist_obj
dimnames, while the second column is renamed through the di_name
argument.`
