Hi,
I experience a very strange behaviour when trying to instanciate a S4 class. A call like 'r <- new("MyClass", foo="bar")' returns apparently cleanly, but in fact a subsequent use of 'r' results in a 'r does not exist error message'. After a bit of hunting with 'debug', it seems that
the bug is in 'initialize' (or one of the functions it calls in turn).
All this while using R-devel from Nov. 16th (R-2.0.1-devel).
I did manage to make a simple example to reproduce the bug, but to do so one needs few packages from the bioconductor project. If this is not yet know and one shows interest, I can provide the few lines of code needed to reproduce it.
Two points:
a) yes, please alsways specify a simple reproducible example when talking about a "bug";
b) if this "bug" does not appear in R-2.0.1 but only in the current R-devel, it might be worth to wait a couple of days. Perhaps someone is including some new functionality and has not yet finished the updates.
