The code presented here comes from P. Legendre's website and is slightly different (updated) compared to the original code published as Appendix S4 of the paper (among other changes, the name of
percentagedifference method has been changed into
%difference, and one more dissimilarity metric has been added, namely
ruzicka). Help file for the function is here.
