AlonDS

This data set was collected by Alon <em>et. al.</em> and consists of 2000 genes measured on 62 patients: 40 diagnosed with colon cancer and 22 healthy patients. The patient status is described by the factor <squote>grouping</squote> and the gene values are given by the numeric variables <squote>genes.1</squote> through <squote>genes.2000</squote>.

datasets

Performs Linear Discriminant Analysis in High Dimensional
        problems based on reliable covariance estimators for problems
        with(many) more variables than observations. Includes routines
        for classifier training, prediction, cross-validation and
        variable selection.
