rank.abund.fric.null: Random cumulative Functional Richness (FRic) across rank...

In NGSwenson/lefse_0.5: Phylogenetic and Functional Analyses for Ecology

Description

Randomly quantifies Functional Richness (FRic) index beginning with the 3 most common species in a community and recalculating as increasingly rare species are added.

Usage

rank.abund.fric.null(my.sample, my.traits)

Arguments

my.sample	A community data matrix
my.traits	A trait matrix with row names being species names

Value

rank.abund.fric.null The FRic value first for the 3 most common species and then for the 3 most common until the rarest species is added where the names on the trait matrix have first been randomized.
