rdiversity (version 2.3.0)

sub_gamma: Subcommunity gamma diversity

Description

Calculates similarity-sensitive subcommunity gamma diversity (the contribution per individual toward metacommunity diversity). This measure may be calculated for a series of orders, represented as a vector of qs.

Usage

sub_gamma(meta, qs)

Value

sub_gamma returns a standard output of class rdiv

Arguments

meta

object of class metacommunity

qs

vector of mode numeric containing q values

Examples

pop <- data.frame(a = c(1, 3), b = c(1, 1))
row.names(pop) <- paste0("sp", 1:2)
pop <- pop / sum(pop)
meta <- metacommunity(pop)
