\begin{Description}\relax
A text file containing the Khan micorarray data with
random missing values introduced for illustrative purposes
\end{Description}
\begin{Usage}
\begin{verbatim}
   data(khanmiss)
\end{verbatim}
\end{Usage}
\begin{Format}\relax
The data set \code{khanmiss} 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.
