Using C++ will reduce portability of your code. Using C++'s STL (not R's stl, so it is a good idea to spell out jargon) will reduce the portability further.
R itself does not use C++, and although a C++ compiler is found, it is only very mininally tested (and in particular its headers and libraries are not checked). Some of us have only rather old C++ compilers on commercial Unixen.
