Dear Mister,
I'm a new user of the "R" programm, and I've got a simple question. I analyse microarray with this programm, I have tranformed my data in a data file, after that, I normalize my data and create  a MA list. Il the Excel tab I obtain, there is a column called "Coefficent", I wish to know if this column represent the "fold change" of my gene? And the second question is to know: From this value, how can I know the level of surexpression of my gene? Is a coefficient upper 1 means surexpression, no induction between -1 and 1 and repression for lower value of -1?
Thanks a lot,
Regards,
