Dear all,

I am trying to get the scatter plot matrix (function "pairs") and MVA plot (function "mva.pairs") of multiple affy chips.  When I use postscript() or pdf() to save the graphs generated from 12 affy mouse chips using the "pairs" function, the size of the file is about 500 MB. I would appreciate any suggestions that can effectively reduces the size of these plots.
