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

     Reads a comma-delimited file containing the expression values of
     the dilution and spike-in data sets and creates a 'ExpressionSet'

_U_s_a_g_e:

     read.dilution(filename)
     read.spikein(filename,cdfName=c("hgu95a","hgu133a"),remove.xhyb=TRUE)
     read.newspikein(filename)

_A_r_g_u_m_e_n_t_s:

filename: character containing the filename to be read.

 cdfName: are we reading data from the hgu95a or hgu133a spike-in
          experiment?

remove.xhyb: logical. If 'TRUE' possible cross hybridizers are removed
          from the HGU133A spikein. See 'remove.hgu133a.xhyb'.

_D_e_t_a_i_l_s:

     The file to be read must be comma-delimited with the first row
     containing the cel filenames (case sensitive). The first column
     must be the Affymetrix gene identifiers. 'read.dilution' will put
     things in the right place.

     'read.newspikein' is a wrapper to read results from the hgu133a
     spikein experiment.

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

     An 'ExpressionSet'.

_A_u_t_h_o_r(_s):
