similarity_to_dissimilarity: Convert similarity metrics to dissimilarity metrics

Description

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

Usage

similarity_to_dissimilarity(similarity, include_formula = TRUE)

Value

A data.frame with additional class bioregion.pairwise, providing dissimilarity metric(s) between each pair of sites based on a similarity object.

Arguments

similarity

The output object from similarity() or dissimilarity_to_similarity().

include_formula

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