     The data set 'khan' consists of 2310 rows and 65 columns. Row 1
     has the  sample labels, Row 2 has the class labels. The remaining
     rows are gene expression. Column 1 is a dummy gene number.  Column
     2 is the gene name. Remaining columns are gene expression.

     The data set 'khanEset' contains an 'exprSet' representation of
     the  same data. There is additionally a vector named,
