I use RInside and Rcpp packages to make a few R calls from C++ for a bioinformatics project I'm doing. I'm trying to get my code working on a big cluster on campus to speed up the analysis I need to do on real data now that my methodological development is done. The admins for that cluster were only able to get RInside 0.2.1, and I think Rcpp 0.7.9 (maybe 0.7.8?) compiled properly. This has meant that operator[] has disappeared.
I was setting up my R instance with the standard: RInside R(0, NULL); And then was creating Rcpp::NumericVector instances, filling them, then doing: R["var.name"] = my_numeric_vector; How do I accomplish this assignment in the older versions? I've been looking through the header files at the assign functions, but: R.assign(my_numeric_vector, "var.name"); doesn't work, as there are only assign functions defined to take standard STL vectors as the thing to be assigned to the given variable name in the R instance. Do I have to rewrite the code so the NumericVector instances are just std::vector<double> instances? Is there some other function other than the assign functions that I can use? Is there a built in function in NumericVector to cast it to a STL vector of doubles? I really appreciate the vast work you've put into this package. It's saved my butt a few times! Thanks, Matt
