[R] Visibility of methods in different namespaces

[Thomas Etheber]

Dear List,

I have posted my questions to the r-devel list as well, but I think this 
list is read by more users, and maybe someone from this list may point 
me in the right direction. Here is the corresponding thread:

https://stat.ethz.ch/pipermail/r-devel/2010-July/058003.html

I am sorry for the double post, but I am working on this problem now for 
quite a time and I am getting annoyed and thinking of just renaming the 
functions. Is any help available?

Thanks in advance.
Thomas
