In affy: Methods for Affymetrix Oligonucleotide Arrays

Description

Scale array intensities in a AffyBatch.

Usage

normalize.AffyBatch.constant(abatch, refindex=1, FUN=mean, na.rm=TRUE)
normalize.constant(x, refconstant, FUN=mean, na.rm=TRUE)

Arguments

abatch	an instance of the AffyBatch-class.
x	a vector of intensities on a chip (to normalize to the reference).
refindex	the index of the array used as a reference.
refconstant	the constant used as a reference.
FUN	a function generating a value from the intensities on an array. Typically mean or median.
na.rm	parameter passed to the function FUN.
