[R] How do I call a masked function in a package without a namespace?

[Dirk Koschuetzki]

Hello,

I work with two packages sna and graph from CRAN resp. Bioconductor. Both  
packages have a function called "degree". Therefore one of the functions  
is masked by the other and which one gets called depends on the order of  
loading. The problem is that both package do not have a namespace,  
therefore calling the masked function with "package::degree" does not  
work. See the following transcript:

Is there a way to call the masked function via a different way?
And I wold like to create my own function degree which will of course  
masked both functions and should therefore be able to call both functions.

Thanks for any hint!
