Classes Defined by this Package

Description

This package defines the following data classes.

RGList
A class used to store raw intensities as they are read in from an image analysis output file, usually by read.maimages.
MAList
Intensities converted to M-values and A-values, i.e., to contrasts on the log-scale. Usually created from an RGList using MA.RG or normalizeBetweenArrays.
MArrayLM
Store the result of fitting gene-wise linear models to the normalized intensities or log-ratios. Usually created by lmFit.

Objects of these classes may be subsetted and multiple data objects may be combined.

All of these classes belong to the virtual class LargeDataObject. A show method is defined for LargeDataOjects which uses the utility function printHead.
