The data is taken from HSAUR3 package's household data. We use housing, service, and food variables and normalize them to be unit-norm so that each observation is projected onto the 2-dimensional sphere. The data consists of 20 males and 20 females and has been used for clustering on the unit hypersphere.



a named list containing

a length-\(n\) factor for class label.
