Usage

EnforceOutgroup(tree, outgroup)

Arguments

tree

Either: a tree of class phylo; or a character vector listing the names of all the taxa in the tree, from which a random tree will be generated.

outgroup

Character vector containing the names of taxa to include in the outgroup.

Value

EnforceOutgroup returns a tree of class phylo where all outgroup taxa are sister to all remaining taxa, without modifying the ingroup topology.
