C++ classes to embed R in C++ applications The 'RInside' packages makes it easier to have "R inside" your C++ application by providing a C++ wrapper class providing the R interpreter. As R itself is embedded into your application, a shared library build of R is required. This works on Linux, OS X and even on Windows provided you use the same tools used to build R itself. Numerous examples are provided in the eight subdirectories of the examples/ directory of the installed package: standard, mpi (for parallel computing) qt (showing how to embed 'RInside' inside a Qt GUI application), wt (showing how to build a "web-application" using the Wt toolkit), armadillo (for 'RInside' use with 'RcppArmadillo') and eigen (for 'RInside' use with 'RcppEigen'). The example use GNUmakefile(s) with GNU extensions, so a GNU make is required (and will use the GNUmakefile automatically). Doxygen-generated documentation of the C++ classes is available at the 'RInside' website as well.
Easy embedding of R inside C++
Provided with the package itself are eight subdirectories with examples: from
more than a dozen basic command-line examples (in directory
graphical user-interfaces (using both Qt and
Wt), linear algebra with
computing with MPI to a sandboxed server.
The simplest example (modulo its header) is examples/standard/rinside_sample0.cpp
// for the embedded R via RInsideint
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.
