norm_rho {rdiversity}

Normalised rho (low level diversity component)

Description

Calculates the low-level diversity component necessary for calculating normalised rho diversity.

Usage

norm_rho(meta)

Arguments

meta

object of class metacommunity

Details

Values generated from norm_rho() may be input into subdiv() and metadiv() to calculate normalised subcommunity and metacommunity rho diversity.

Value

norm_rho returns an object of class powermean

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 rho component
r <- norm_rho(meta)
subdiv(r, 1)
metadiv(r, 1)
