A data frame with 214 observations, where the problem is to
predict the type of glass in terms of their oxide content
(i.e. Na, Fe, K, etc). The study of classification of types of
glass was motivated by criminological investigation. At the
scene of the crime, the glass left can be used as evidence...
if it is correctly identified!
