\description{
    Death rates per 100 in Virginia in 1940.  The death rates are
    cross-classified by age group (rows) and population group
    (columns).  The age groups are: 50-54, 55-59, 60-64, 65-69, 70-74
    and the population groups are Rural/Male, Rural/Female, Urban/Male
    and Urban/Female.

    This provides a rather nice 3-way analysis of variance example.
