Hi,
I would like to invoke an R-function from a program written in ANSI C. Assume that I have written an R script "myRexample" and I want to invoke it from C. I assume that my R script loads its data from a datafile so no arguments need to be passed between my C program and R. Following R-exts.pdf (section 4.7), I write the following main:
#include "my.h" /* includes all standard h-files */
#include <R.h> /* according to R-exts.pdf */
#include <Rinternals.h>
SEXP myRexample();
int main(int argc,char **argv) {
.External("myRexample"); /* invoking my R script */
exit(0);
} /* end of main() */
Is this a correct interpretation, given that R is properly installed in the (unix) main frame?
I'm grateful for any advice on how to proceed.
regards
Ralf Östermark
