Calling R functions from VC ++

I need to run aggregate functions from R in my C ++ code. Is there a way to call them from my C ++ code? I am using VS 2005, do I need to include any header files or link any libraries? I installed R using the standard Windows installer provided on their website.

Yours faithfully,

Short:

  • As was said quite often, R does not build VS * by itself; it makes a reference to C-code rigidly, but it is also possible to C ++ - code is impossible (since the function header information is not standardized).

  • Rcpp RInside Windows,  Windows toolchain. ( RInside , .)

    Rcpp VS * (..  , R )

  • VS *,   Rserve.

    , Rcpp/RInside;   R API .
