setwise_beta: Calculate pairwise/ setwise beta diversities

In T-Engel/betaC: Standardize beta-diversity by sample coverage

Description

This is an internal helper function for beta_stand(). Beta-diversity is calculated for the number of samples in x and the the given index. Therefore, x must have exactly N_samples rows. This is a security feature to ensure that users don't try to calculate another set size than given by the number of rows in x. Use beta_stand()!

Usage

setwise_beta(x, setsize = 2, func, ...)

Arguments

x	A site by species matrix.
setsize	number of sites in the matrix
func	function returning the desired beta-diversity metric
...	additional argumets passed on to func

Details

If extrapolate = F, observed S will be returned if N_stand exceeds sample size.

Value

A single numeric value for the beta diversity index.
