Using Rccp as a C++ STL without using using R

Question

I understand that Rcpp is an R package for integration between C++ and R. I have a code which uses Rcpp for this. But I am looking to use the C++ code directly. Is it possible to get Rcpp as any usual C++ STL so that I can use the functions of Rcpp as it is (eg: the as in Rcpp)?

Answer 1

Sure:

R> cppFunction("double mysum(std::vector<double> x) { \
                   double s = std::accumulate(x.begin(), x.end(), 0.0); return s;}")
R> mysum(c(0.1, 0.2, 0.3))
[1] 0.6
R> 

There are plenty of STL examples in the documentation, the Rcpp Gallery and other places as e.g. my talks. Or of course the Rcpp book.
