[Rcpp-devel] Method with default params using RCPP_MODULE

I am exposing a c++ class using Rcpp. It works fantastic, but my problem is
how to implement a method which has default params. I have the class:

class myClass {


        int myMethod(int param1, int param2 = 0);

and I config the module:

RCPP_MODULE(mymodule) {
        .method("myMethod", &myClass::myMethod)

When I try to execute the function in R passing only the mandatory param I
get an error because R does not recognize the function, but if I execute it
with both params, it works great. So, how can I define the method in order
to be able to execute it without informing the optional params?

Thank you,
