Thanks for your explanation. callbackFunction will be prefect in my case.<br>Just wondering can I pass an R function like below to a c++ function in a separate cpp file (e.g., in src folder of my package)? <br><br>funx <- cfunction(signature(N = "integer" , xvec = "numeric",<b> fun = "function"</b> ),<br>
cpp, , Rcpp = TRUE, include = "using namespace Rcpp; ")<br><br><br>thanks<br><br>-- Ariful<br><br><div class="gmail_quote">On Wed, Mar 21, 2012 at 9:00 PM, Dirk Eddelbuettel <span dir="ltr"><<a href="mailto:edd@debian.org">edd@debian.org</a>></span> wrote:<br>

</div>Then you do /not/ start with the package skeleton generator, which is for<br>
use with _packages loaded into R_.<br>
<br>
RInside extends standalone C++ program with their own main() function.<br>
<br>
<br>
If what you want is to call back into R from a loadable package, do not look<br>
at RInside but rather look at the examples/ directory of Rcpp, particularly<br>
callbackFunctions/ which has a working example.<br>

</div>I can't speak to that, but folks have used Rcpp and RInside merrily on OS X<br>
in both 32 and 64 bit.<br>
<br>
Then again, maybe you don;t even want RInside.<br>

</div>No, that is not how it used. You misunderstand.<br>
