[BioC] agi4x44kpreprocess package

[Francois Pepin]

Hi Erika,

I have never used that package, but it seems to be mostly a wrapper 
around limma for those steps. What happens if you use 
read.maimages(files, source='agilent') directly?

You might also want to make sure that you have red values if you look 
directly in your raw text file.

And please post the output from sessionInfo(). This will make it easier 
for people to understand which type of installation you have, and 
generally makes it easier to catch if the problem.
