norm_sub_alpha: Normalised subcommunity alpha diversity

Description

Calculates similarity-sensitive normalised subcommunity alpha diversity (the diversity of subcommunity j in isolation. This measure may be calculated for a series of orders, repesented as a vector of qs.

Usage

norm_sub_alpha(meta, qs)

Arguments

meta

object of class metacommunity

qs

vector of q values

Value

Returns a standard output of class tibble, with columns: measure, (norm alpha), q (parameter of conservatism), type_level (), type_name (label attributed to type), partition_level (level of diversity, i.e. subcommunity), partition_name (label attributed to partition), and diversity.

# NOT RUN {
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 subcommunity alpha diversity
norm_sub_alpha(meta, 0:2)
