datasets

Efficient implementations of functions for the creation,
modification and analysis of phylogenetic trees.
Applications include:
generation of trees with specified shapes;
analysis of tree shape;
rooting of trees and extraction of subtrees;
calculation and depiction of node support;
calculation of ancestor-descendant relationships;
import and export of trees from Newick, Nexus (Maddison et al. 1997)
<doi:10.1093/sysbio/46.4.590>,
and TNT <http://www.lillo.org.ar/phylogeny/tnt/> formats;
and analysis of splits and cladistic information.
