rotateNodes | R Documentation |
The function rotateNodes
is a simple wrapper for rotate
which rotates a set of nodes or all nodes.
The function rotate.multi
finds all possible rotations around a multifurcating node, given by node
. This will be an object of class "multiPhylo"
, assuming that the node specified is indeed a multifurcation.
The function allRotations
computes all possible rotated trees for a given input phylogeny. For a binary tree, this is generally two raised to the power of the number of internal nodes (so a very large number, if N is even modest in size).

All three functions also address the problem that the product of multiple rotations from rotate
can be non-compliant with the implicit "phylo"
standard because the tip numbers in tree$edge
are not in numerical order 1:n
for n
tips.
An object of class "phylo"

for rotate.multi
or allRotations
