Calculates similarity-sensitive normalised metacommunity beta diversity (the effective number of distinct subcommunities. This measure may be calculated for a series of orders, represented as a vector of qs.

norm_meta_beta(meta, qs)

Arguments

meta

object of class metacommunity

qs

vector of mode numeric containing q values

Value

norm_meta_beta 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)
