Converting a table with speciation and extinction events to evolutionary distances

Description

Function to convert a table with speciation and extinction events to mean evolutionary distances between each species and the rest of the community

Usage

L2ED(L, t)

Arguments

L

Matrix of events as produced by pdd_sim:

- the first column is the time at which a species is born in Mya
- the second column is the label of the parent of the species; positive and negative values indicate whether the species belongs to the left or right crown lineage
- the third column is the label of the daughter species itself; positive and negative values indicate whether the species belongs to the left or right crown lineage
- the fourth column is the time of extinction of the species; if the fourth element equals -1, then the species is still extant.
