RMA preprocess BufferedMatrix {BufferedMatrixMethods}

R Documentation

RMA preprocessing functions that work on BufferedMatrix objects

Description

This group of functions can be used to apply the RMA background correction, Quantile normalization and Median polish summarization to data stored in a BufferedMatrix object.

Usage

bg.correct.BufferedMatrix(x, copy=TRUE)
normalize.BufferedMatrix.quantiles(x, copy=TRUE)
BufferedMatrix.bg.correct.normalize.quantiles(x, copy=TRUE)

Arguments

x	a BufferedMatrix containing data to be processed
copy	should the BufferedMatrix be copied or should the input object be changed on output

Value

In the case of normalize.BufferedMatrix.quantiles and bg.correct.BufferedMatrix a BufferedMatrix is returned. The function median.polish.summarize returns a matrix.

The function BufferedMatrix.bg.correct.normalize.quantiles carries out both pre-processing steps with a single command.
