Check out the webbioc package in BioC-Devel. It does web-based analysis 
of Affymetrix data from CEL files to annotated HTML lists with 
hyperlinks to online databases. It also creates M vs. A, QQ-Normal, and 
multiple testing procedure selectivity plots. The image quality issue 
was solved by using the GhostScript bitmap() device to super-sample PNG 
images at 4X resolution and then scale them back down to nice 
antialiased images with Netpbm.

I don't know if this will do what you want. (I'm looking for someone to 
add a cDNA chip input module.) Perhaps the code might be useful for 
ideas. (Mostly Perl calling R in batch mode.) For more info, see the 
vignette and R News article, respectively:
