Load 'household' data

Source: R/data_household.R

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.

data(household)

Format
