In case there is any chance that you could turn your part of the source from
C into C++, try RcppTemplate from CRAN --- it makes interfacing R and C++ a
whole lot easier.  I cannot recommend it highly enough. 

But if you don't yet know C++ it provides yet another learning curve so you
may not want to go there quite yet...


Hell, there are no rules here - we're trying to accomplish something.
