[BioC] ExpressionSet without normalization

[Juan Carlos Oliveros]

Hi,

the "rma" function of the "affy" package can be applied without 
normalizing the data. Use the option "normalize=FALSE". The same apply 
for the background correction ("background=FALSE")

For more details check the function with, "?rma" in the R console.

best,

Juan Carlos
