clusterdata
Wrapper function for linkage
and cluster
.
If cutoff is used, then clusterdata
calls linkage
and
cluster
with default value, using cutoff as a threshold value
for cluster
. If cutoff is an integer and greater or equal to 2,
then cutoff is interpreted as the maximum number of cluster desired
and the "MaxClust" option is used for cluster
.
If cutoff is not used, then clusterdata
expects a list of pair
arguments. Then you must specify either the "Cutoff" or "MaxClust" option
for cluster
. The method and metric used by linkage
, are
defined through the "linkage" and "distance" arguments.
