There is no walkthrough or tutorial -- because there are six example directories with a large number of examples.
Look at the ones in the standard/
directory, which should take you from very simple to more advanced.
Here is for example the simplest hello-world example, rinside_sample0.cpp
:
#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 init string, ignoring returns
exit(0);
}
Just say 'make rinside_sample0' (or make -f Makefile.win rinside_sample0
on Windows). (Note that on Windows you need to get several DLLSs into your path etc pp -- Linux is easier that way._
Also look at earlier questions here in the [rinside]
tag.
