betaFD_dist: Functional betadiversity among several communities

In ibartomeus/fundiv: tools to calculate several functional trait diversity indexes

Description

Calculate functional trait beta diversity for several communities using Petchey and Gaston 2002 index and Carvalho et al. 2012 decomposition and creates a dist object.

Usage

betaFD_dist(W, S)

Arguments

W	matrix containing the abundances of the species in S (or presence-absence, i.e. 0 or 1). Rows are sites and species are columns. NA not tolerated. In addition, the species labels in W and S must be identical.
S	matrix or data frame of functional traits. Traits can be numeric, ordered, or factor. NAs are tolerated. All species in W should be present. Species should be ordered alphabetically.

Value

Btot Total Betadiversity dist object

B_3 Beta diversity due to replacement dist object

Brich Beta diversity due to richness diferences dist object

quality the ouptput will print the quality of the dendogram representation. clustering performance is assessed by the correlation with the cophenetic distance

Examples

ex1 <- betaFD_dist(W = dummy$abun, S = dummy$trait)
