In phytools: Phylogenetic Tools for Comparative Biology (and Other Things)

Drop tips or extract clade from tree with mapped discrete character

Description

This function drops one or multiple tips from an object of class "simmap".

Usage

## S3 method for class 'simmap'
drop.tip(phy, tip, ...)
## S3 method for class 'simmap'
keep.tip(phy, tip, ...)
extract.clade.simmap(tree, node)

Arguments

phy	an object of class "simmap".
tip	name or names of species to be dropped (or kept).
node	node number for the root node of the clade to be extracted.
...	optional arguments. Currently the logical argument untangle which if set to TRUE will call untangle before returning the "simmap" object to the user.
tree	for extract.clade.simmap, an object of class "simmap".

Details

Equivalent to drop.tip and keep.tip but for a tree with a mapped discrete character.

extract.clade.simmap is functionally equivalent to extract.clade but preserves discrete character mappings on the tree.

Following drop.tip in ape, the returned tree is always in "cladewise" order.

Value

A modified object of class "phylo" containing the elements maps and $mapped.edge with the time spent in each state along each edge of the tree.
