These data are the results of an experiment in which different groups of rats were 
  exposed to different concentration levels of ethylene thiourea (ETU), which is a 
  decomposition product of a certain class of fungicides that can be found in treated 
  foods (Graham et al., 1975; Rodricks, 1992, p.133).  In this experiment, the outcome of 
  concern was the number of rats that developed thyroid tumors.

datasets

Graphical and statistical analyses of environmental data, with 
  focus on analyzing chemical concentrations and physical parameters, usually in 
  the context of mandated environmental monitoring.  Major environmental 
  statistical methods found in the literature and regulatory guidance documents, 
  with extensive help that explains what these methods do, how to use them, 
  and where to find them in the literature.  Numerous built-in data sets from 
  regulatory guidance documents and environmental statistics literature.  Includes 
  scripts reproducing analyses presented in the book "EnvStats:  An R Package for 
  Environmental Statistics" (Millard, 2013, Springer).
