### Description

Returns the ID number or the labels of the leaves in a dendrogram, in the order in which they are found.

### Usage

    order.dendrogram(x)
    ## S3 method for class 'dendrogram':
    labels(x)

### Arguments

x | an object of class "dendrogram", as produced by as.dendrogram.

### Details

order.dendrogram is not a method for the generic order function. Its argument list differs and it does not always return a permutation of seq_along(labels(x)).
Value

order.dendrogram | returns a vector of leaf ID numbers. The vector length is the number of leaves in the dendrogram.
labels.dendrogram | returns a vector of leaf "labels" attributes. The vector length is the number of leaves in the dendrogram.
