Dear all, while writing an iterator hack for the problem encountered a few hours ago and posted here:
https://www.mail-archive.com/rcpp-devel@lists.r-forge.r-project.org/msg06810.html, I have noticed that the default behavior for the range constructor for e.g. Rcpp::NumericVector seems to be to allocate fresh memory: arma::mat obj1(5, 10, arma::fill::zeros); Rcpp::NumericVector obj2(obj1.begin(), obj1.begin() + 5); obj2 = 1.; Rprintf("obj1: %f, obj2: %f\n", obj1(0,0), obj2(0)); yields that obj1 and obj2 differ. Is there any way to tell the range constructor to reuse existing memory similarly to the (Rcpp)Armadillo feature copy_aux_mem = false or am I missing something more subtle? Thanks in advance for any hints, Gregor _______________________________________________ Rcpp-devel mailing list Rcpp-devel@lists.r-forge.r-project.org https://lists.r-forge.r-project.org/cgi-bin/mailman/listinfo/rcpp-devel
