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

Details

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.
