Followup question: How does one invoke the cpu-profiler? You need to give a path to the binary, which is actually something like /usr/lib/R/bin/exec/R but that needs several environment variables to be set. Do you get around this by using littler? _______________________________________________ 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
