writeAncestors

a phylogenetic tree or set of trees as an object of class <code>"phylo"</code> or <code>"multiPhylo"</code>.

tree

a vector of ancestral states, a list containing the ancestral states and 95-percent confidence intervals (as from <code><a rd-options="" href="/link/fastAnc?package=phytools&version=0.7-70" data-mini-rdoc="phytools::fastAnc">fastAnc</a></code> or <code><a rd-options="" href="/link/ace?package=phytools&version=0.7-70" data-mini-rdoc="phytools::ace">ace</a></code>, or a list of such results.

an optional string with the filename for output.

file

an integer indicating the number of digits to print for branch lengths and ancestral character values.

digits

a string indicating whether to output the result in simple Newick (i.e., <code>"phylip"</code>) or Nexus format.

format

additional arguments including <code>x</code>: a vector of character values, in which case ancestral states are estimated internally using <code>fastAnc</code>; and <code>CI</code>: a logical value indicating whether or not to estimate 95-percent confidence intervals.

This function writes a tree to file with ancestral character states and (optionally) 95-percent confidence intervals stored as node value..

phylogenetics

comparative method

input/output

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.
