Calculate the tip diversification rates (DR) for a phylogenetic tree

Source: R/DR.R
DR.Rd

This function computes the tip diversification rates Jetz et al., 2012, or DR, for an inputted ultrametric phylogenetic tree.

Usage

DR(tree)

Arguments

tree

phylo. An ultrametric phylogenetic tree in the "phylo" format.

Value

The function returns a data frame containing the tip diversification rates for all species within the inputted phylogenetic tree.
