normalize: Normalize an object

In Bioconductor/BiocGenerics: S4 generic functions used in Bioconductor

Normalize an object

Description

A generic function which normalizes an object containing microarray data or other 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.

Usage

normalize(object, ...)

Arguments

object	A data object, typically containing microarray data.
...	Additional arguments, for use in specific methods.

Value

An object containing the normalized data.
