Takes a tbl_tree object representing a tree, and extracts a subtree at a
given node.
Arguments
- tree_tibble
A
ConvenientTblTreeobject.- node
The ID number of the node to base the subtree, or a
FocalCladeobject.- ...
Other arguments (currently ignored)
Value
A subtree represented in the tbl_tree class of the tidytree
package. This tibble has an extra node.orig column providing the old node
IDs, because the node IDs in the object are renamed during the extraction
of the subtree.
