R: Get/set attributes of dendrogram's leaves

get_leaves_attr {dendextend} | R Documentation

## Get/set attributes of dendrogram's leaves

### Description

Get/set attributes of dendrogram's leaves

### Usage

    get_leaves_attr(dend, attribute, simplify = TRUE, ...)

### Arguments

`dend` | a dendrogram object
`attribute` | character scalar of the attribute (`attr`) we wish to get/set from the leaves
`simplify` | logical. If TRUE (default), then the return vector is after using `unlist` on it.
`...` | not used

### Value

A vector (or a list) with the dendrogram's leaves attribute

### Source

Heavily inspired by the code in the function `labels.dendrogram`, so credit should go to Martin Maechler.

### See Also

### Examples

    # define dendrogram object to play with:
    hc <- hclust(dist(USArrests[1:3,]), "ave")
    dend <- as.dendrogram(hc)

    # get_leaves_attr(dend) # error :)
    get_leaves_attr(dend, "label")
    labels(dend, "label")
    get_leaves_attr(dend, "height") # should be 0's
    get_nodes_attr(dend, "height")

    get_leaves_attr(dend, "nodePar")

    get_leaves_attr(dend, "leaf") # should be TRUE's
    get_nodes_attr(dend, "leaf") # conatins NA's

    get_leaves_attr(dend, "members") # should be 1's
    get_nodes_attr(dend, "members") #

    get_leaves_attr(dend, "members",simplify = FALSE) # should be 1's
