The RInside package provides a few classes for seamless embedding ofR inside ofC++ applications by relying onRcpp.

Provided with the package itself are nine subdirectories with examples: from more than a dozen basic command-line examples (in directorystandard) to graphical user-interfaces (using bothQt and Wt), linear algebra withArmadillo andEigen, parallel computing with MPI to asandboxed server, and (since release 0.2.16) a simple (and more limited) interface for embedding insice C applications.

The simplest example (modulo its header) isexamples/standard/rinside_sample0.cpp

#include<RInside.h>// for the embedded R via RInsideintmain(int argc,char *argv[]) {    RInsideR(argc, argv);// create an embedded R instance    R["txt"] ="Hello, world!\n";// assign a char* (string) to 'txt'    R.parseEvalQ("cat(txt)");// eval the init string, ignoring any returnsexit(0);}

TheQt example directory producesthis application for showing how to use R (to estimate densities) inside a C++ executable (providing the GUI):

The code is portable across operating systems. Similar, theWt example directorycontains this C++-based web application doing the same:
