But you also have to be able to identify if it is a S3 function or an S4 method (or an ordinary function). The reason I find this so much of a problem is that when you are teaching R, one of the first things you want to do is teach your students how to use help. However, you can't teach them to use it effectively until they know an awful lot about how the call semantics of R.
