Which node id is common to a group of labels
This function identifies which edge(s) in a tree has group of labels ("tips") in common. By default it only returns the edge (node) with the heighest id.
which_node(dend, labels, max_id = TRUE, ...)
dend |
a dendrogram dend |
labels |
a character vector of labels from the tree |
max_id |
logical (TRUE) - if to return only the max id |
... |
ignored. |
An integer with the id(s) of the nodes which includes all of the labels.
