[BioC] printTipLoess normalization with missing observations

I am analysing a data set which has missing
incensities corresponding to one specific print-tip
for all slides. I want to do printTipLoess
normalization using maNorm() function from marrayNorm
package. It did not work for my data set and I am
getting the following error message:

> dat.Norm = maNorm(dat.RAW, norm="p")
Error in simpleLoess(y, x, w, span, degree,
parametric, drop.square, normalize,  : 
        invalid `x'

Is there any way to use maNorm() successfully for this
kind of data set.

Thanks in advance,
