Rcpp 0.8.0 on CRAN
...the "R side" as an R condition.
For example :
SEXP foo( ) {
try {
// user code here
} catch( std::exception& __ex__){
forward_exception_to_r( __ex__ ) ;
}
// return something here
}
Alternatively, functions can enclose the user code with the macros BEGIN_RCPP
and END_RCPP, which provides for a more compact way of programming. The
function above could be written as follows using the macros:
SEXP foo( ) {
BEGIN_RCPP
// user code here
END_RCPP
// return something here
}

Rcpp with OpenMP - Need example Makevars
...ently I started developing a Rcpp package "OpenMPTest".
Within that package I want to use OpenMP, as in the following code example:
// header file
#include <omp.h>
using namespace Rcpp ;
RcppExport SEXP testOpenMP( SEXP nThreads ) ;
// cpp file
SEXP testOpenMP( SEXP nThreads ) {
BEGIN_RCPP
NumericVector numberThreads = NumericVector( nThreads );
omp_set_num_threads( numberThreads(0) );
#pragma omp parallel
{
// Code inside this region runs in parallel.
printf("Hello!\n");
}
END_RCPP
}
As I am an absolute newbie with writing C++ extensions and have not...

Help with integrating R and c/c++
Hi,
I have been using R for close to two years now and have grown quite
comfortable with the language. I am presently trying to implement an
optimization routine in R (Newton Rhapson). I have some R functions that
calculate the gradient and hessian (pre requisite matrices) fairly
efficiently. Now, I have to call this function iteratively until some
convergance criterion is reached. I think the
