Ordering or Labels of the Leaves in a Dendrogram

Theses functions return the order (index) or the "label" attribute for the leaves in a dendrogram. These indices can then be used to access the appropriate components of any additional data.

Keywords
manip
Usage
order.dendrogram(x)

# S3 method for dendrogram labels(object, …)

Arguments
x, object
a dendrogram (see as.dendrogram).
additional arguments
Details

The indices or labels for the leaves in left to right order are retrieved.

Value

A vector with length equal to the number of leaves in the dendrogram is returned. From r <- order.dendrogram(), each element is the index into the original data (from which the dendrogram was computed).

See Also

Examples
library(stats) set.seed(123) x <- rnorm(10) hc <- hclust(dist(x)) hc$order dd <- as.dendrogram(hc) order.dendrogram(dd) ## the same : stopifnot(hc$order == order.dendrogram(dd)) d2 <- as.dendrogram(hclust(dist(USArrests))) labels(d2) ## in this case the same as stopifnot(identical(labels(d2), rownames(USArrests)[order.dendrogram(d2)]))
