Dear people at Bioconductor, First of all I would like to compliment you on your great site and your even greater software packages. I started working with R+ only recently - and since I am a biologist (and relativly new to the topic of Microarrys as well) and not a statistician kept very close to the path you have shown me. But there is one thing I would like to do that I did not find instructions for. So here is my question: We have a tool called GeneSpring (I am sure you are familiar with it) that I used for data-analysis. My problem is that I can only import Affy- Scaled data into it taking away much of its power (for example doing a median-polish...). I would like to know how I can tell R (or any other tool you might know of), to give me the raw chip data - unmodified. Or a recommandation how to import RMA normalized data without fuss. As I have already told you I am relatively new to that field of study - maybe my questions are rather naive, but any help is appreciated!
