Nothing
Besides functions for the calculation of similarity and multiple plot similarity measures with binary data (for instance presence/absence species data) the package contains some simple wrapper functions for reshaping species lists into matrices and vice versa and some other functions for further processing of similarity data (Mantellike permutation procedures) as well as some other useful stuff for vegetation analysis.
