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

     Plot the variation in the averages for a particular probe / bead
     type

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

     plotProbeVariation(BSData, id, log=TRUE, ylim=range(0,16),...)

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

  BSData: an BeadSummaryList containing bead summary data

      id: character string specifying the ProbeID to be plotted

     log: if TRUE the values will be transformed to be log2 scale
          before plotting

    ylim: sets the range of the y axis on the plot

     ...: other graphical parameters to be passed

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

     The function plots the average (log2 or unlogged) value for the
     specified ProbeID against array index. This function is more
     suited to BeadChip data where the number of arrays is relatively
     small (3 or 4). 

     The plotOnSAM function can be used for the results of SAM
     experiments to relate average probe values to position on the SAM.

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

     Plot is produced on current graphical device
