dissimilarity_to_similarity: Convert dissimilarity metrics to similarity metrics

Description

This function converts a data.frame of dissimilarity metrics (beta diversity) between sites into similarity metrics.

Usage

dissimilarity_to_similarity(dissimilarity, include_formula = TRUE)

Value

A data.frame with the additional class bioregion.pairwise, providing similarity metrics for each pair of sites based on a dissimilarity object.

Arguments

dissimilarity

the output object from dissimilarity() or similarity_to_dissimilarity().

include_formula

a boolean indicating whether metrics based on custom formula(s) should also be converted (see Details). The default is TRUE.
