%description
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.
