     This data set was copied from 'library(faraway)' and the name
     changed to 'ozone1' to prevent a name clash. The data were
     originally made available by Leo Breiman who was a consultant on a
     project where the data were generated. Example analyses using
     these data may be found in Faraway and in Hastie and Tibshirani.
