[BioC] warnings with affy package

[Phguardiol at aol.com]

Hi
I ve been running an analysis with the affy package and I am getting some warnings. I dont exactly know what to think about these...(see below)
I m using a P4, winXP, 1G0 RAM with R1.7 and the development packages (the last one from today !)
