map.traits {treats}

Maps a trait on a tree

Description

Simulates one or more trait specified through a "traits" onto one or multiple trees.

Usage

map.traits(traits, tree)

Arguments

traits

A "traits" object (see make.traits).

tree

A "phylo" or "multiPhylo" object.

Details

This function simulates the trait(s) on the tree using the tree's branch length.

Value

A "treats" object containing the tree and the traits.

Examples

## Simulating a random tree with branch length
my_tree <- rtree(20)

## Creating three different traits objects:
## A Brownian Motion
bm_process <- make.traits(process = BM.process)
## An Ornstein-Uhlenbeck process
ou_process <- make.traits(process = OU.process)
## No process (just randomly drawing values from a normal distribution)
no_process <- make.traits(process = no.process)

## Mapping the three traits on the phylogeny
bm_traits <- map.traits(bm_process, my_tree)
ou_traits <- map.traits(ou_process, my_tree)
no_traits <- map.traits(no_process, my_tree)

## Plotting the topology and the different traits
oldpar <- par(mfrow = c(2,2))
plot(my_tree, main = "Base topology")
plot(bm_traits, main = "Mapped BM")
plot(ou_traits, main = "Mapped OU")
plot(no_traits, main = "Mapped normal trait")
par(oldpar)
