[BioC] Exploding PLASQ Inevitable : slot exprs AffyBatch

[Richard Finney]

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 ...
