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

     Read csv files which contain bead-level data without x and y
     positions for each bead. An BeadLevelList can be created with
     limited functionality available  or used to create an
     BeadSummaryList (bead summary data).

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

     readNonXYData(files, max_length)

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

   files: List of filenames to be read

max_length: numeric value specifying the length of the longest file to
          be read

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

     This function can be used to read bead-level data generated by the
     Illumina scanning software but which does not contain the bead
     centre coordinates for each bead. Files of this type may have all
     undecoded beads removed from the output, hence a different  number
     of beads may appear in each file. As matrices in R are required to
     have the columns of the same length we need to specify  the length
     of the longest file to be read in to create a matrix large enough
     to hold the data. 

     The function creates an BeadLevelList containing foreground and
     ProbeID for each bead on each array

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

     BLData object with list components R and ProbeID
