## 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.

year

  Years 1936 to 1972.

incidence

  Rate of melanoma cancer per 100,000 population.

### Note

This dataset is not related to the `melanoma` dataset in the boot package with the same name.

The S-PLUS 6.2 help for the melanoma data says that the incidence rate is per million, but this is not consistent with data found at the National Cancer Institute (http://www.nci.nih.gov).
