han 1 from the dataset. The default calculates the median of pairwise overlaps
for the whole community using the harmonic means of abundances of the species pairs as
weights, which minimizes the effect of outliners and rare species.If the argument
<code>weight_type = "none"</code>, no weights are used for the calculation of mean/median. If
<code>weight_type = "mean"</code>, arithmetic means of abundances are used as weights. To change the
output to mean, specify the argument <code>output = "mean"</code>.</p
