justPlier {plier}R Documentation

Implements the PLIER algorithm

Description

Provides a wrapper around Affymetrix's API to provide an implementation of the PLIER alogrimth

Usage

justPlier(eset=ReadAffy(),replicate=1:length(eset),get.affinities=FALSE,normalize=FALSE,norm.type="together",augmentation=0.1,defaultaffinity=1.0,defaultconcentration=1.0,attenuation=0.005,seaconvergence=0.000001,seaiteration=3000,gmcutoff=0.15,probepenalty=0.001,concpenalty=0.000001,usemm=TRUE,usemodel=FALSE,fitaffinity=TRUE,plierconvergence=0.000001,plieriteration=3000,dropmax=3.0,lambdalimit=0.01,optimization=0)

Arguments

eset An AffyBatch object containing the raw data
replicate A factor containing the replicate structure to use for grouping samples
get.affinities If TRUE, then return affinities in the description@preprocessing slot of the ExpressionSet object
normalize If TRUE then apply quantile normalization to the probes before generating expression calls
norm.type Can be 'separate', 'pmonly', 'mmonly' or 'together'
augmentation Model parameter
defaultaffinity Model parameter
defaultconcentration Model parameter
attenuation Model parameter
seaconvergence Model parameter

Details

This function is a thin wrapper around the Affymetrix implementation. For more details, including information about the meaning of the different model parameters, please see the plier documentation at www.affymetrix.com.

Value

An Expression set containing PLIER generated expression calls
