hl

a numeric vector for the correlations with head length

hb

a numeric vector for the correlations with head breadth

fb

a numeric vector for the correlations with face breadth

ft

Details

Hartigan suggests performing factor analysis on this data set to determine the minimum number of principal components. In addition, a joining algorithm can be performed on the data set. Note that the data frame has the variable names as row names. It can be used directly by the eigen function.
