jaccard

0-1-matrix. Columns are species, rows are regions.

regmat

Computes Jaccard distances between the columns of a 0-1-matrix.

cluster

spatial

Distance-based parametric bootstrap tests for clustering,
        mainly intended for presence-absence data and abundance data
        (clustering of species distribution ranges). Jaccard,
        Kulczynski, quantitative Kulczynski and geco distance measures,
        clustering of presence-absence and abundance data, and nearest
        neighbor based noise detection (R port of Byers and Raftery's
        (1998) "NNclean"). Main functions are prabtest, abundtest (for
        testing), prabclust (for clustering), prabinit (for preparing
        the data) and NNclean (for noise detection). The help-pages for
        prabtest, abundtest and prabclust contain simple standard
        executions. Note that the use of the package mclust (called by
        function prabclust) is protected by a special license, see
        http://www.stat.washington.edu/mclust/license.txt, particularly
        point 6.
