Re-roots a phylogenetic tree at an arbitrary position along an edge.
reroot(tree, node.number, position=NULL, interactive=FALSE, ...)
A phylogenetic tree in "phylo"
format.
a phylogenetic tree in "phylo"
format.
number of the node descending from the target branch in tree$edge
- this can also be a tip in which case the node number is the index number of the tip in tree$tip.label
.
position along the target edge at which to re-root the tree. If not supplied, then the tree will be re-rooted at the node or tip.
logical value indicating whether to use interactive mode (defaults to interactive=
FALSE
).
arguments to be passed to plotTree
for interactive=TRUE
only.

This function had an error for rootings along edges descended from the root node for phytools<=0.2-47. This should be fixed in the present version. Now uses paste.tree
, root
, and splitTree
internally. Earlier versions also had an error related to node labels. This should be fixed in phytools>=0.4-47.
