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

     Retrieves the raw intensity information from a given array stored
     in a 'BeadLevelList' object.

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

     getArrayData(BLData,which="G",array=1,log=TRUE)

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

  BLData: 'BeadLevelList'

   which: character string specifying which intensities to obtain.
          Possibilities are '"ProbeID"', '"GrnX"', '"GrnY"', '"G"',
          '"Gb"' for single channel data and additional columns '"R"'
          and '"Rb"' for two-colour data

   array: numeric value giving the array we are interested in

     log: if TRUE log2 of the raw intensities are returned

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

     'getArrayData' retrieves the raw data from 'which' column of
     'array'.  When intensity data is chosen, the data can be on the
     log2 scale when 'log==TRUE'.

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

     A vector containing the intensities

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