[BioC] Mising data

[Joyce Gu]

Hello,
I am using marrayInput packages to do my data analysis. After I read into my 
data with read.marrayRaw function. I found that lots of my data is labelled 
"NA". I use name.Gf="Ch1 Median",name.Rf="Ch2 Median",name.Gb=" Ch1 B 
Median",name.Rb="Ch2 B Median" command, I am wondering how marrayClass 
transformed data. Is still M vs A or what.
I want to normalize my data with this packages, then export to do further 
analysis with other software.

Any explanation is greatly appreciated about this algorithm

Thanks
