[BioC] how to reduce the file size of scatter plot matrix

I am using R/Bioconductor under windows. When I want to copy some plot into
word or PowerPoint, I often select the option "copy as matfile" instead of
"copy as bmp". I don't know if that could serves your needs.

Good luck,

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.
