similarity_to_dissimilarity: Convert similarity metrics to dissimilarity metrics

Description

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

Usage

similarity_to_dissimilarity(similarity, include_formula = TRUE)

Value

A data.frame with additional class bioregion.pairwise.metric, 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 if the metrics based on your own formula(s) should be converted (see Details). This argument is set to TRUE by default.
