Returns the edge parameter of the two trees consistent with the speficied NNI rearrangement
DoubleNNI(parent, child, edgeToBreak)
the first column of the edge matrix of a tree of class
phylo
, i.e. tree$edge[, 1]
the second column of the edge matrix of a tree of class
phylo
, i.e. tree$edge[, 2]
(optional) integer specifying the index of an edge to bisect/prune,
generated randomly if not specified.
Alternatively, set to -1
to return a complete list
of all trees one step from the input tree.
the tree$edge
parameter of the two trees consistent with the specified rearrangement
