Glass

<p>A data frame with 214 observation containing examples of
  the chemical analysis of 7 different types of glass. The problem is to
  forecast the type of class on basis of the chemical analysis.  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!).</p>

datasets

A collection of artificial and real-world machine learning
benchmark problems, including, e.g., several
data sets from the UCI repository.
