Add species to genus on a phylogeny


This function adds an additional species to a genus on a phylogeny.

Usage, species, genus=NULL, where=c("root","random"))



an object of class "phylo".


string contain species name in the format "Genus_species" or "Genus species".


optional argument containing the genus to which species is to be attached. If NULL then genus will be extracted from species.


location to attach species to the tree. where="root" will cause the species to be attached to the MRCA of all members of genus. where="random" will cause species to be attached at random to the subtree descended from the MRCA of all members of genus.


If genus contains only one species and where="root", then species will be attached midway along the branch leading to the one species. If where="random" then species will be added at a random position along the edge. If genus cannot be found in the tree, then the original tree is returned and a warning printed. If the tree is not ultrametric, then the resultant tree may not contain branch lengths and a warning will be printed. If genus is non-monophyletic then species will be attached to the most inclusive group containing members of genus and a warning will be printed.


An object of class "phylo".
