[R] S4 Methods with large numbers of args using memory

Thanks all to the people on the r-help list for the backtick help.

I've run into another problem. With my SWIG C++ wrapper for R, I'm finding that S4 generic functions with large numbers of argument (such as 10 or 11) seem to be taking up a lot of memory especially when a lot of the arguments are set to missing.

This happens because I'm generating S4 methods to wrapper C++ functions with optional arguments. Each wrapper can take several meg of heap causing my R program to quickly run out of heap memory.

Any ideas as to what the problem is and any possible way of working around it?
