funtooNorm(object, type.fits = "PCR", ncmp = 4, force = FALSE,
  sex = NULL)

## S4 method for signature 'SampleSet'
funtooNorm(object, type.fits = "PCR", ncmp = 4,
  force = FALSE, sex = NULL)

Arguments

object

Object of class SampleSet

type.fits

Choice between "PCR" or "PLS" (default="PCR")

ncmp

Number of components included in the analysis (default=4)

force

If set to TRUE, forces the normalization procedure to re-compute

sex

Boolean vector if male. if NULL Beta values from ChrY are used for classification.

Details

This is a generic function which applies to autosomes and the X chromosome. Chromosome Y requires separate analysis as there are few probes on Y. We use a straightforward quantile normalization applied to males only.

Value

a S4 object of class SampleSet containing the normalized signal
