In the context of the SSC library, maybe. Note that the example below uses C language code (and there is a reason) But what you are overlooking is that in general you CANNOT mix code from Visual Studio and MinGW for purposes of Rcpp -- and in general you CANNOT mix C++ code from different compilers. So unless you get the source code for SSC and learn how to build an Rcpp package __from sources__ ie without an external library you will be out of luck. This is all stated in the Rcpp-FAQ.
