nni {phangorn} | R Documentation |
nni
returns a list of all trees which are one nearest neighbor interchange away. rNNI
and rSPR
are two methods which simulate random trees which are a specified number of rearrangement apart from the input tree. Both methods assume that the input tree is bifurcating. These methods may be useful in simulation studies.
