sounds logical.
BTW, I read "Writing R Extensions" in HMTL form under Windows R 1.8.1, and
it doesn't mention exportClass.
Also it doesn't describe how to use S4 classes (or package "methods") and
namepaces together.
Hence, I think it is not up to date.

Now R CMD check distr runs smoothly, thanks for your help.
