phylo2L

Function to convert phylogeny to a table with speciation and extinction events

Description

Converting a phylogeny to a table with speciation and extinction events

Usage

phylo2L(phy)

Arguments

phy

A phylogeny of the phylo type

Value

L

Matrix of events as produced by dd_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.
