\title{ Melanoma skin cancer incidence }
\description{
These data from the Connecticut Tumor Registry present
age-adjusted numbers of melanoma skin-cancer incidences per
100,000 people in Connectict for the years from 1936 to 1972.
}
\usage{melanoma}
\format{
A data frame with 37 observations on the following 2 variables.
\describe{
\item{year}{Years 1936 to 1972.}
\item{incidence}{Rate of melanoma cancer per 100,000 population.}
}
}
\note{
This dataset is not related to the \code{\link[boot]{melanoma}}
dataset in the \bold{boot} package with the same name.
The S-PLUS 6.2 help for the melanoma data says that the incidence rate is
per \emph{million}, but this is not consistent with data found at the
National Cancer Institute (\url{http://www.nci.nih.gov}).
