Easy embedding of R inside C++

The RInside package provides a few classes for seamless embedding of R inside of C++ applications by relying on Rcpp.

Provided with the package itself are eight subdirectories with examples: from more than a dozen basic command-line examples (in directory standard) to graphical user-interfaces (using both Qt and Wt), linear algebra with Armadillo and Eigen, parallel computing with MPI to a sandboxed server.

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

#include<RInside.h>// for the embedded R via RInsideintmain(int argc, char *argv[]){RInside R(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)}

The Qt example directory produces this 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, the Wt example directory contains this C++-based web application doing the same:

The RInside web page has some more details.
