Calculates observed F and mean squares for the residuals and among sites. This
function is a helper for prep_data_nestedsymmetric().

)A data frame containing the resulting PERMANOVA table.
ecological community data.
label for the community data.
appropriate distance/dissimilarity metric (e.g. Gower, Bray–Curtis, Jaccard, etc).
Mathematical function to reduce the weight of very dominant species.
which algorithm to use for the calculation? At the moment, the only option is "nested.symmetric".
