_D_e_s_c_r_i_p_t_i_o_n:

     Gene expression data (500 genes and 38 tumor mRNA samples)  from
     the leukemia microarray study of Golub et al.  (1999). Original
     data set contain 3051 genes

_V_a_l_u_e:

   golub: matrix of gene expression levels for the  38 tumor mRNA
          samples, rows correspond to genes  (500 genes) and columns to
          mRNA samples.

golub.cl: numeric vector indicating the tumor  class, 27 acute
          lymphoblastic leukemia (ALL) cases  (code 0) and 11 acute
          myeloid leukemia (AML) cases (code 1). 

golub.gnames: a matrix containing the names of  the 500 genes for the
          expression matrix 'golub'.  The three columns correspond to
          the gene 'index',  'ID', and 'Name', respectively.
