PolarTransforms: Polar transformations

In beadarraySNP: Normalization and reporting of Illumina SNP bead arrays

Description

Perform polar transforms on Illumina Golden Gate bead arrays

Usage

   RG2polar(object,trig=FALSE)
   polar2RG(object,trig=FALSE)

Arguments

object	SnpSetIllumina object
trig	Logical, use geometric distance intensity. Otherwise use addition of intensities

Details

RG2polar transforms the R and G matrices to theta and intensity matrices. Note that the intensity value is the sum of R and G and not the geometric distance to the origin.

polar2RG performs the reverse transformation

Value

This function returns an SnpSetIllumina object.
