C++ classes to embed R in C++ (and C) applications A C++ class providing the R interpreter is offered by this package making it easier to have "R inside" your C++ application. 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 nine 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'), 'eigen' (for 'RInside' use with 'RcppEigen'), and 'c_interface' for a basic C interface and 'Ruby' illustration. The examples 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.
