dendextend_labels.dendrogram: Labels of the Leaves in a Dendrogram
Description
This is the same function as labels.dendrogram. It is used inside
dendextend_options, and thus allows the function to be updated when loading
the dendextendRcpp package.
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).
