[Rd] Using STL containers in R/C++

[Prof Brian Ripley]

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.
