raw_gamma: Gamma (low level diversity component)

Description

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

Usage

raw_gamma(meta)

Value

raw_gamma returns an object of class powermean

Arguments

meta

object of class metacommunity

Details

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

Examples

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)
