R: Set/place new labels in a dendrogram

set_labels {dendextend} | R Documentation

## Set/place new labels in a dendrogram

### Description

Convenience functions for updating the labels of a dendrogram. set_labels and place_labels differs in their assumption about the order of the labels. * set_labels assumes the labels are in the same order as that of the labels in the dendrogram. * place_labels assumes the labels has the same order as that of the items in the original data matrix. This is useful for renaming labels based on some other columns in the data matrix.

### Usage

    set_labels(dend, labels, ...)

### Arguments

`dend` | a dendrogram object
`labels` | A vector of values to insert in the labels of a dendrogram.
`...` | Currently ignored.

### Value

The updated dendrogram object

    ss <- c(50, 114, 17, 102, 76, 10, 107, 84, 31, 37, 49, 106, 44, 119,
          104, 145, 67, 85, 12, 77, 22, 136, 38, 135, 70)

       small_iris <- iris[ss, ]

       small_iris[,-5] %>%
       dist() %>%
       hclust(method = "complete") %>%
       as.dendrogram() %>%
       color_branches(k = 3) %>%
       color_labels(k = 3) %>%
       plot()

       # example for using place_labels
       small_iris[,-5] %>%
          dist() %>%
          hclust(method = "complete") %>%
          as.dendrogram() %>%
          color_branches(k = 3) %>%
          color_labels(k = 3) %>%
          place_labels(paste(small_iris$Species, 1:25, sep = "_")) %>%
          plot()

       # example for using set_labels

          color_labels(k = 3) %>%
