(2) As the OO design of R is different to that of C++, some isses exist when creating an interface between these two systems. (I said these two are 'different', I didn't say which one is better or which one is uglier. So please save the posts on criticising the designs for somewhere else. I am trying to make these two designs talk to each other without judging them.)
(3) One of these issues is about handling overloaded member functions in C++ in the form of R classes. Following the discussion followed by my previous post, I have decided to wrap the C++ in the form of S4 classes.
(4) Some more assumptions:
(a) A C++ class may have any arbitrary number of overloaded functions each of them have some arbitrary number of arguments.
(b) To create the equivalent 'overloaded functions' in R, we need to have a generic function with several methods. The arguments (signature) of each of these methods are determined by the generic function.
(c) In order to make the automatic wrapper as general as possible, it should not know about the arguments of the overloaded functions.
(5) And finally the question: How to define the generic function so that it covers any unknown arguments of its methods? Apparently simply using '...' does not work.
