Find lowest common branch were the two items are shared

Source: R/cor_bakers_gamma.R

Given two vectors, for two items, of cluster belonging - the function finds the lowest branch (e.g: largest number of k clusters) for which the two items are in the same cluster for the two trees.

lowest_common_branch(item1, item2, ...)

Arguments

item1

a named numeric vector (of cluster group with names of k level)

item2

a named numeric vector (of cluster group with names of k level)

...

not used

Value

The first location (from left) where the two vectors have the same A dendrogram, after adjusting the members attr in all of its nodes.
