This is what I'm used to while working with compiled code for R.
Two cautious words of advice: Don't. I did that too (which is how you copied it from the HPC Tutorial notes) but using things like inline is just so much easier. Now, it's a little tricky with RcppArmadillo and the ordering of the header files but that's why we gave you the corresponding RcppArmadillo.package.skeleton() -- Regards, Dirk _______________________________________________ Rcpp-devel mailing list [email protected] https://lists.r-forge.r-project.org/cgi-bin/mailman/listinfo/rcpp-devel
