Renumber() numbers the nodes and tips in a tree to conform with the phylo standards.




A tree of class phylo.


Renumber() returns a tree of class phylo, numbered in a Cladewise fashion consistent with the expectations of ape functions.


The ape class phylo is not formally defined, but expects trees' internal representation to conform to certain principles: for example, nodes should be numbered sequentially, with values increasing away from the root.

Renumber() attempts to reformat any tree into a representation that will not cause ape functions to produce unwanted results or to crash R.

Preorder() provides a faster and simpler alternative, but also rotates nodes.
