Reorder a dendrogram

Description

There are many different orderings of a dendrogram that are consistent with the structure imposed. This function takes a dendrogram and a vector of values and reorders the dendrogram in the order of the supplied vector, maintaining the constraints on the dendrogram.

Usage

reorder(x, ...)
reorder.dendrogram(x, wts, ...)

Arguments

x	The object to be reordered
wts	The weights for reordering.
...	additional arguments

Details

Using the weights the leaves of the dendrogram are reordered so as to be in an order as consistent as possible with the weights.
