Prints a set of clusters (R.W. Payne).
Option
UNITS = variate or text |
Names to use for the units in the clusters |
|---|
Parameters
CLUSTERS = pointers |
Clusters to print |
|---|---|
EXTRA = pointers |
Extra information to print |
Description
HPCLUSTERS can print a set of clusters. The clusters are specified by the CLUSTERS parameter, in a pointer containing a variate for each cluster. The variates contain the numbers of the units in their respective clusters (and the numbers are the row or column positions of their units in the similarity matrix used by HCLUSTER). The cluster pointers can be formed by the HFCLUSTERS procedure.
The UNITS option can be set to a text or a variate, to provide textual labels or other numbers to use for the units of the clusters, instead of the numbers in the CLUSTER variates.
You can supply extra information to print, in a pointer, using the EXTRA parameter. It should contain variates, texts or factors, with the same number of values as the CLUSTERS pointer.
Option: UNIT.
Parameters: CLUSTERS, EXTRA.
