normalize.quantiles2 {RefPlus} | R Documentation |
Quantile normalization to a reference set.
normalize.quantiles2(X, Reference.Quantiles)
X |
A matrix of probe intensity data to be reference quantile normalized. |
Reference.Quantiles |
A vector of the reference quantiles that the probe intensities of a sample is normalized to. |
The function quantile normalized the probe intensities of a set of microarrays to a set of reference quantiles which are formed by a set of reference microarrays.
The reference quantile normalized probe intensities.
