_D_e_s_c_r_i_p_t_i_o_n:

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

_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 come delimeted with the first row
     containing the cel fileneames (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 'exprSet'.
