rescaleSimmap: Rescale object of class '"simmap"'

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

Rescale object of class "simmap"

Description

Scales a tree with a mapped discrete character ("simmap" object), or a set of such trees, to an arbitrary total height, preserving the relative time spent in each state along each edge.

Usage

## S3 method for class 'simmap'
rescale(x, model="depth", ...)
## S3 method for class 'multiSimmap'
rescale(x, model="depth", ...)
rescaleSimmap(tree, ...)

Arguments

x	object of class "simmap" or "multiSimmap" to be rescaled.
model	model to use to rescale the tree. Currently the only option is "depth".
...	parameter of the model to use in rescaling. Currently the only parameter is depth for model="depth".
tree	for rescaleSimmap, object of class "simmap" to be rescaled.

Details

Replaces rescaleTree (now rescale.phylo) in the geiger package for the "simmap" object class. rescaleSimmap is now a redundant alias for the method rescale.simmap.

Value

An object of class "simmap" or "multiSimmap".

Examples

## load anoletree
data(anoletree)
## rescale to have total depth of 50
rescaled_anoletree<-rescale(anoletree,depth=50)
## plot rescaled tree
plot(rescaled_anoletree,ftype="i",fsize=0.6,
	mar=c(5.1,1.1,1.1,1.1))
axis(1,at=seq(0,50,by=10))
par(mar=c(5.1,4.1,4.1,2.1)) ## reset margin to default
