reorder {mva} | R Documentation |
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.
reorder(x, ...) ## S3 method for class 'dendrogram': reorder(x, wts, ...)
x |
The object to be reordered |
wts |
The weights for reordering. |
... |
additional arguments |
Using the weights the leaves of the dendrogram are reordered so as to be in an order as consistent as possible with the weights.
From reorder.dendrogram
