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

     Write MA-plots to files in PNG format, six plots to a file in a 3
     by 2 grid arrangement.

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

     plotMA3by2(MA, prefix="MA", path=NULL, main=colnames(MA), zero.weights=FALSE, common.lim=TRUE, ...)

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

      MA: an 'MAList' or 'RGList' object, or any list with components
          'M' containing log-ratios and 'A' containing average
          intensities

  prefix: character string giving prefix to attach to file names

    path: character string specifying directory for output files

    main: character vector giving titles for plots

zero.weights: logical, should points with non-positive weights be
          plotted

common.lim: logical, should all plots on a page use the same axis
          limits

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

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

     This function writes a series of PNG format files to disk. Each
     file contains six MA-plots in three rows and two columns. The
     layout is optimized for A4-sized paper.

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

     No value is returned, but one or more files are written to the
     working directory. The number of files is determined by the number
     of columns of 'MA'.

     An overview of diagnostic functions available in LIMMA is given in
     09.Diagnostics.
