normalize {affy} | R Documentation |
A generic function which normalizes microarray data. Normalization is intended to remove from the intensity measures any systematic trends which arise from the microarray technology rather than from differences between the probes or between the target RNA samples hybridized to the arrays.

object. For example, for the main class in the affy
package use
?normalize.AffyBatch
.
Other Bioconductor packages include some related generic functions:

the limma package.
