     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.

_F_o_r_m_a_t:

     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.

     '_e_x_p_r_s' the matrix containing estimates expression levels with
          rows as genes and columns as patients (dimensions: 12,625 by
          22)

     '_s_e._e_x_p_r_s' the matrix with standard error estimates (gcrma returns
          a 0 by 0 matrix)

     '_d_e_s_c_r_i_p_t_i_o_n' no information is available for the description
          slot, which is of class MIAME

     '_a_n_n_o_t_a_t_i_o_n' "hgu95av2"

     '_n_o_t_e_s' there are no notes for this object

     '_r_e_p_o_r_t_e_r_I_n_f_o' unknown (NULL)

     '_p_h_e_n_o_D_a_t_a' 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 

     '_c_l_a_s_s_V_e_r_s_i_o_n' no version

_S_o_u_r_c_e:

     The CLL microarray data came from  Dr. Sabina Chiaretti at
     Division of Hematology, Department of Cellular Biotechnologies and
     Hematology, University La Sapienza, Rome, Italy and Dr. Jerome
     Ritz at Department of Medicine, Brigham and Women's Hospital,
     Harvard Medical School, Boston, Massachusetts.
