[BioC] Robust Spline Normalization (lumi) - illumina data matrix

[Pan Du]

Hi Sharon,

The "rsn" function in the lumi package accepts either an object of
ExpressionSet class (or inherited class like LumiBatch) or a data matrix. So
you can directly use it. Please read the help of "rsn" function for more
details. You can also try other normalization methods in other packages.
