[BioC] Exploding PLASQ Inevitable : slot exprs AffyBatch

[pingzhao Hu]

   Hi Richard,
   You need to change a little bit the code.
round(ReadAffy(filenames = paste(celFolder,
i, sep = "/"))@exprs) 

   to
   round(exprs(ReadAffy(filenames = paste(celFolder,i, sep = "/")))))
   in
   celExtNorm and celExtract functions.
   Thanks for Ben told me this before.

   -------------------------------------
I'm getting a mysterious error message 
"no slot of name "exprs" for this object of class
"AffyBatch""

Anybody got any ideas on what crime I committed?

I got the latest greatest Bioconductor stuff
yesterday.

The gory details ...
