Traitspace (version 1.0)

distTraitspace: Calculate the distances

Description

Calculates the distances between the predicted and true/observed relative abundances (by default) or species distributions if byrow = FALSE.

Usage

distTraitspace(result, obs = NULL, byrow = TRUE)

Arguments

result

The output from the traitspace function (class traitspace)

obs

The observed matrix - where, each row corresponds to a site and each column to a species - the order of sites and species should match with the order in which they appear in the predicted matrix. By default, NULL, will generate the observed matrix using t

byrow

By default, TRUE, will compare the relative abundances. If FALSE, will compare the species distribution.

Value

• A list of distances calculated using the following measures: Euclidean, Manhatten, Hellinger, Kullback-Leibler and Bhattacharya. It calculates both the average distance (averages across all sites or species) as well as individual distances.
