slice.tree: Time slicing a tree.

In dispRity: Measuring Disparity

Time slicing a tree.

Description

Time slicing through a phylogenetic tree.

Usage

slice.tree(tree, age, model, FAD, LAD)

Arguments

tree	A phylo object with a root.time element.
age	A single numeric value indicating where to perform the slice.
model	One of the following models: "acctran", "deltran", "random", "proximity", "equal.split" or "gradual.split". Is ignored if method = "discrete". See chrono.subsets for the models description.
FAD, LAD	The first and last occurrence data.

Examples

set.seed(1)
## Generate a random ultrametric tree
tree <- rcoal(20)

## Add some node labels
tree$node.label <- letters[1:19]

## Add its root time
tree$root.time <- max(tree.age(tree)$ages)

## Slice the tree at age 0.75
tree_75 <- slice.tree(tree, age = 0.75, "deltran")
