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

branches_attr_by_lists {dendextend} | R Documentation

## 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).

    library(dendextend)

    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) %>%
