[BioC] Masking Features

[Isaac Neuhaus]

I tried to use the affy package (version 0.7) to analyze a set of hybs
for which I masked all the features in the cel file for a few genes.
When I normalize the data using the normalize method I get the following
error:

> data <- ReadAffy(CDFfile="HG_U95Av2.CDF", CELfiles=cels,
chip.names=names, rm.mask=T, verbose=F)
> ndata <- normalize(data, method="quantile", verbose=F)
Error in as.vector(data) : NA/NaN/Inf in foreign function call (arg 1)
Execution halted

Can anybody help me?
