Rquantile

This method ensures that the red (second) channel has the same empirical distribution across arrays, leaving the $ \mathbf{M}$-values (log-ratios) unchanged. Both Gquantile and Rquantile normalisation have the implicit effect of changing the red and green log-intensities by equal amounts [5].
