</blockquote><h2>Description</h2><blockquote>
<p>The code included in Raup-Crick.txt allows one to
perform the null model analyses described in the text. The resulting values represent the degree
to which observed numbers of shared species between any two sites differ from
what would have been expected by random chance given the number of species
co-occurring in each of two localities, and the designated regional species
pool.</p>
