I want you guys to know that I appreciate all the effort that you put into the Rcpp package and this list. I am obviously one of the early people to hurdle the new "lowered bar" for C++ development in R.
I have developed a function that builds a series of vectors and a matrix of undetermined size. Rather than attempt dynamic objects (which I wouldn't know how to do anyway) I have been able to initialize with row dimensions that cannot be exceeded on these objects. I expect that code that merely assigns values to these addresses will run faster than code that must allocate space for each row entry anyway. But, at the end of the process, my code realizes the true extent of these objects. It would be really nice to clean these up before return to R. I am aware of a Dimension class, but really don't know how to go about using this in this case. For the vectors it was relatively simple to execute a loop of erase() methods: // this works perfectly for(int t=newTimes.size()-1; t>row;t--) { newTimes.erase(t); } Alas, for the Rcpp::IntegerMatrix this was not so easy. Rcpp::IntegerMatrix opd (exists and has been populated) for(int v=0; v<num_opl v++) { for(int t=newTimes.size()-1; t>row;t--) { opd(_,0).erase(t); } } This results in the compiler error: 'struct Rcpp::Matrix<13>::Column' has no member named 'erase' I'm sorry, but I am stuck. _______________________________________________ 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
