aptg - Automatic Phylogenetic Tree Generator
Generates phylogenetic trees and distance matrices from a
list of taxon names, or from a higher taxon expanded down to a
chosen lower rank. Trees are obtained as induced subtrees of
the Open Tree of Life synthetic tree using the 'rotl' package
(Michonneau, Brown and Winter, 2016,
<doi:10.1111/2041-210X.12593>). Expansion of a higher taxon to
its descendants uses 'taxize' (Chamberlain and Szocs, 2013,
<doi:10.12688/f1000research.2-191.v2>).
