I suggest you read up a little on the search path and how R does lexical scoping (sections 6.3.5 and 10.7 in R-Intro). The short version of that is that unless you specifically name the package that the function is from, R will look inside the current function, then in the global environment, then some other places. If you have problems with names of things being hidden, a quick hack is to rename the hidden item. If you want a less abstract answer then please post a commented, minimal, self-contained, reproducible code example. Regards, Richie.
