_D_e_s_c_r_i_p_t_i_o_n:

     Creates foreground-background plots.

_U_s_a_g_e:

     plotFB(RG, array=1, lim="separate", pch=16, cex=0.2, ...)

_A_r_g_u_m_e_n_t_s:

      RG: an 'RGList' object.

   array: integer giving the array to be plotted. Corresponds to
          columns of 'R', 'G', 'Rb' and 'Gb'.

     lim: character string indicating whether the red and green plots
          should have '"separate"' or '"common"' x- and y- co-ordinate
          limits.

     pch: vector or list of plotting characters. Defaults to integer
          code 16.

     cex: numeric vector of plot symbol expansions.

     ...: any other arguments are passed to 'plot'

_D_e_t_a_i_l_s:

     A foreground-background plot is a plot of log2-foreground vs
     log2-background for a particular channel on a particular two-color
     array. This function produces a pair of plots, one for green and
     one for red, for a specified array.

     See 'points' for possible values for 'pch', 'col' and 'cex'.

_V_a_l_u_e:

     A plot is created on the current graphics device.
