branches_attr_by_lists: Change col/lwd/lty of branches from the root down to clusters...

In dendextend: Extending 'dendrogram' Functionality in R

Change col/lwd/lty of branches from the root down to clusters defined by list of labels of respective members

Description

The user supplies a dend, lists, and type of condition (all/any), and TF_values And the function returns a dendrogram with branches col/lwd/lty accordingly

Usage

branches_attr_by_lists(
  dend,
  lists,
  TF_values = c(2, 1),
  attr = c("col", "lwd", "lty"),
  ...
)

Arguments

dend	a dendrogram dend
lists	a list where each element contains the labels of members in selected nodes down to which the branches shall be adapted
TF_values	a two dimensional vector with the TF_values to use in case a branch fulfills the condition (TRUE) and in the case that it does not (FALSE). Defaults are 2/1 for col, lwd and lty. (so it will insert the first value, and will not change all the FALSE cases)
attr	a character with one of the following values: col/lwd/lty
...	ignored.

Value

A dendrogram with modified branches (col/lwd/lty).

set.seed(23235)
ss <- sample(1:150, 10)

# Getting the dend dend
dend <- iris[ss, -5] %>%
  dist() %>%
  hclust() %>%
  as.dendrogram()
dend %>% plot()

# define a list of nodes
L <- list(c("109", "123", "126", "145"), "29", c("59", "67", "97"))
dend %>%
  branches_attr_by_lists(L) %>%
  plot()

# choose different color, and also change lwd and lty
dend %>%
  branches_attr_by_lists(L, TF_value = "blue") %>%
  branches_attr_by_lists(L, attr = "lwd", TF_value = 4) %>%
  branches_attr_by_lists(L, attr = "lty", TF_value = 3) %>%
