\keyword{datasets}{sCLLex}
\begin{Description}\relax
The exprSet object was obtained by performing gcrma on the AffyBatch object
(CLLbatch).  Two arrays were of questionable quality so these two arrays
(CLL1 and CLL10) were removed before performing gcrma on CLLbatch.  The
sCLLex exprSet object has 22 samples and 12,625 genes.  The Affymetrix
hug95av2 arrays were used and the 22 samples came from 22 CLL patients that
were either classified as stable or progressive in regards to disease
progression.
\end{Description}
\begin{Usage}
\begin{verbatim}data(sCLLex)\end{verbatim}
\end{Usage}
\begin{Format}\relax
An exprSet object with 22 samples and 12,625 genes.  The
Affymetrix hgu95av2 array was used and gcrma was used for preprocessing the
AffyBatch object.
\describe{
\item[\code{exprs}] the matrix containing estimates expression levels with
rows as genes and columns as patients (dimensions: 12,625 by 22)
\item[\code{se.exprs}] the matrix with standard error estimates (gcrma
returns a 0 by 0 matrix)
\item[\code{description}] no information is available for the description
slot, which is of class MIAME
\item[\code{annotation}] "hgu95av2"
\item[\code{notes}] there are no notes for this object
\item[\code{reporterInfo}] unknown (NULL)
\item[\code{phenoData}] a data frame with two variables: SampleID and
Disease (from the disease data frame); SampleID is the CEL file and
Disease is a factor with 2 levels: progressive or stable, based on the
patient's CLL disease progression 
\item[\code{classVersion}] no version
