ID Numbers or Labels of the Leaves in a Dendrogram
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. |
