common_subtrees_clusters: Find clusters of common subtrees

Description

Gets a dend and the output from "nodes_with_shared_labels" and returns a vector (length of labels), indicating the clusters forming shared subtrees

Usage

common_subtrees_clusters(dend1, dend2, leaves_get_0_cluster = TRUE, ...)

Value

An integer vector, with values indicating which leaves in dend1 form a common subtree cluster, with ones available in dend2

Arguments

dend1

a dendrogram.

dend2

a dendrogram.

leaves_get_0_cluster

logical (TRUE). Should the leaves which are not part of a larger common subtree get a unique cluster number, or the value 0.

...

not used.

Examples

library(dendextend)
dend1 <- 1:6 %>%
  dist() %>%
  hclust() %>%
  as.dendrogram()
dend2 <- dend1 %>% set("labels", c(1:4, 6:5))
tanglegram(dend1, dend2)

clusters1 <- common_subtrees_clusters(dend1, dend2)
dend1_2 <- color_branches(dend1, clusters = clusters1)
plot(dend1_2)
plot(dend1_2, horiz = TRUE)
tanglegram(dend1_2, dend2, highlight_distinct_edges = FALSE)
