\begin{Description}\relax
A text file containing the Khan micorarray data
\end{Description}
\begin{Usage}
\begin{verbatim}
   data(khan)
   data(khanEset)
\end{verbatim}
\end{Usage}
\begin{Format}\relax
The data set \code{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 \code{khanEset} contains an \code{exprSet} representation of the 
same data. There is additionally a vector named, \code{khan.geneNames}
containing the 2308 gene names. Note that there are 2308 genes and 64 
samples (the numbers given in the preceeding paragraph include labels).
