     The 'geneList' data is compiled from a differential expression
     analysis of the 'ALL' dataset. It contains just a small number of
     genes with the corespondent p-values. The information on where to
     find the GO annotations is stored in the 'ALL' object.

     The 'topDiffGenes' function included in this dataset will select 
     the differentially expressed genes, at 0.01 significance level,
     from 'geneList'.

_S_o_u_r_c_e:

     Generated using the 'ALL' gene expression data. See the "scripts"
     directory.

_E_x_a_m_p_l_e_s:

     data(geneList)

     ## print the object
     head(geneList)
     length(geneList)

     ## the number of genes with a p-value less than 0.01
     sum(topDiffGenes(geneList))
