norm_meta_alpha: Normalised metacommunity alpha diversity

In rdiversity: Measurement and Partitioning of Similarity-Sensitive Biodiversity

Normalised metacommunity alpha diversity

Description

Calculates similarity-sensitive normalised metacommunity alpha diversity (the average similarity-sensitive diversity of subcommunities). This measure may be calculated for a series of orders, represented as a vector of qs.

Usage

norm_meta_alpha(meta, qs)

Arguments

meta	object of class metacommunity
qs	vector of mode numeric containing q values

Value

norm_meta_alpha returns a standard output of class rdiv

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)

# Calculate normalised metacommunity alpha diversity
norm_meta_alpha(meta, 0:2)
