get_leaves_branches_attr: Get an attribute of the branches of a dendrogram's leaves

Description

This is helpful to get the attributes of branches of the leaves. For example, after we use color_branches, to get the colors of the labels to match (since getting the colors of branches to match those of the labels can be tricky). This is based on get_leaves_edgePar.

Usage

get_leaves_branches_attr(dend, attr = c("col", "lwd", "lty"), ...)

Value

A vector with the dendrogram's leaves nodePar attribute

Arguments

dend

a dendrogram object

attr

character, the attr to get. Can be either "col", "lwd", or "lty".

...

not used

Examples

# define dendrogram object to play with:
hc <- hclust(dist(USArrests[1:5, ]), "ave")
dend <- as.dendrogram(hc)

dend <- dend %>%
  color_branches(k = 3) %>%
  set("branches_lwd", c(2, 1, 2)) %>%
  set("branches_lty", c(1, 2, 1))

plot(dend)

get_leaves_branches_attr(dend, "col")
get_leaves_branches_attr(dend, "lwd")
get_leaves_branches_attr(dend, "lty")

labels_colors(dend) <- get_leaves_branches_attr(dend, "col")
plot(dend)
