Hello, I just created a little package, RcppProgress, to display a progress bar to monitor the execution status of a C++ code loop, possibly multihreaded with OpenMP. I also implemented the possibility to check for user interruption, using the work-around by Simon Urbanek. I just uploaded the package on my R-forge project, so you should be able to g...

Dear R experts, recently 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 );

Hi, I was wondering if anybody knew how to trap SIGINTs (ie Ctrl-C) in backend C++ code for R extensions? I'm writing a package that uses the GPU for some hefty matrix operations in a tightly coupled parallel algorithm implemented in CUDA. The problem is that once running, the C++ module cannot apparently be interrupted by a SIGINT, leaving the user sat waiting even if they realise
