### About
The RInside package provides a few classes for seamless embedding of [R](https://www.r-project.org) inside of
C++ applications by relying on [Rcpp](http://www.rcpp.org).
### Examples
Provided with the package itself are nine subdirectories with examples: from more than a dozen basic command-line examples (in directory
`standard`) to graphical user-interfaces (using both [Qt](http://www.qt.io) and [Wt](http://www.webtoolkit.eu/wt)), linear algebra with
[Armadillo](http://arma.sf.net) and [Eigen](http://eigen.tuxfamily.org/index.php?title=Main_Page), parallel computing with MPI to a
sandboxed server, and (since release 0.2.16) a simple (and more limited) interface for embedding insice C applications.
The simplest example (modulo its header) is [examples/standard/rinside_sample0.cpp](inst/examples/standard/rinside_sample0.cpp)
```c++
#include <RInside.h> // for the embedded R via RInside
int main(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 returns
exit(0);
}
```
The [Qt example directory](https://github.com/eddelbuettel/rinside/tree/master/inst/examples/qt) 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](https://github.com/eddelbuettel/rinside/tree/master/inst/examples/wt)
contains this C++-based web application doing the same:
