Description

Converting a table with speciation and extinction events to a set of branching times

Usage

1
 L2brts(L, dropextinct = T) 

Arguments

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.

dropextinct

Sets whether the phylogeny should drop species that are extinct at the present

Value

brts

A set of branching times
