raw_gamma: Gamma (low level diversity component)

Description

Calculates the low-level diversity component necessary for calculating gamma diversity.

Usage

raw_gamma(meta)

Arguments

meta

object of class metacommunity

Value

raw_gamma returns an object of class powermean

Details

Values generated from raw_gamma() may be input into subdiv() and metadiv() to calculate subcommunity and metacommunity gamma diversity.

Examples

# NOT RUN {
pop <- cbind.data.frame(A = c(1,1), B = c(2,0), C = c(3,1))
row.names(pop) <- paste0("sp", 1:2)
pop <- pop/sum(pop)
meta <- metacommunity(pop)

# Calculate gamma component
g <- raw_gamma(meta)
subdiv(g, 1)
metadiv(g, 1)
