reroot

a phylogenetic tree in <code>"phylo"</code> format.

tree

number of the node descending from the target branch in <code>tree$edge</code> - this can also be a tip in which case the node number is the index number of the tip in <code>tree$tip.label</code>.

node.number

position along the target edge at which to re-root the tree. If not supplied, then the tree will be re-rooted at the node or tip.

position

logical value indicating whether to use interactive mode (defaults to <code>interactive=</code> <code>FALSE</code>).

interactive

arguments to be passed to <code>plotTree</code> for <code>interactive=TRUE</code> only.

This function re-roots a phylogenetic tree at an arbitrary position along an edge.

utilities

phylogenetics

A wide range of functions for phylogenetic analysis. Functionality is concentrated in phylogenetic comparative biology, but also includes numerous methods for visualizing, manipulating, reading or writing, and even inferring phylogenetic trees and data. Included among the functions in phylogenetic comparative biology are various for ancestral state reconstruction, model-fitting, simulation of phylogenies and data, and multivariate analysis. There are a broad range of plotting methods for phylogenies and comparative data which include, but are not restricted to, methods for mapping trait evolution on trees, for projecting trees into phenotypic space or a geographic map, and for visualizing correlated speciation between trees. Finally, there are a number of functions for reading, writing, analyzing, inferring, simulating, and manipulating phylogenetic trees and comparative data not covered by other packages. For instance, there are functions for randomly or non-randomly attaching species or clades to a phylogeny, for estimating supertrees or consensus phylogenies from a set, for simulating trees and phylogenetic data under a range of models, and for a wide variety of other manipulations and analyses that phylogenetic biologists might find useful in their research.
