lumiMethyN: Normalize the Illumina Infinium methylation data

In lumi: BeadArray Specific Methods for Illumina Methylation and Expression Microarrays

Description

Normalize the Illumina Infinium methylation data, which is an object in MethyLumiM class.

Usage

lumiMethyN(methyLumiM, method = c("quantile", "ssn", "none"), separateColor = FALSE, verbose = TRUE, overwriteBigMatrix = FALSE, ...)

Arguments

methyLumiM	a MethyLumiM object includes Illumina Infinium methylation data
method	supported normalization methods or user provided function, whose input and output should be a intensity matrix (pool of methylated and unmethylated probe intensities)
separateColor	determine whether to separately process two color channels
verbose	a boolean to decide whether to print out some messages
overwriteBigMatrix	whether to overwrite the result to the BigMatrix data, only valid when the input data is BigMatrix-based
...	other parameters used by corresponding method

Value

Return an object (same class as input methyLumiM) with updated "methylated" and "unmethylated" data matrix after background level adjustment.
