\title{ The ExpressionSet object for the CLL microarray data}
\description{
  The ExpressionSet 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 ExpressionSet 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.

\format{
  An ExpressionSet object with 22 samples and 12,625 genes.  The
