Robustspline and two dimentional loess for two color agilent data

Dear Samaneh Fazeli,

I am guessing that this is question about

  normalizeWithinArrays(RG, method="robustspline")

in the limma package.  When there are no print tips, robust-spline 
normalization reduces to loess normalization.  Hence you should use:

  normalizeWithinArrays(RG, method="loess")

for Agilent arrays.

Best wishes
Gordon
