Hi r-devel, I am working on a R extension. I am writing the function in C++, and in my function it is required a R function object from the user. This R function object will be evaluated thousand of times in my C++ code. I generated the shared library and I loaded it on R. I did several experiments in order to compare the speed of my compiled code vs the speed of the equivalent interpreted code. I was surprise!, the better was the interpreted code!. Then, I ask myself: What is the benefit of compiled code??. I think my problem is in using the function "eval(SEXP f, SEXP rho)" because it takes time!. Am I right?. Then, can someone tell me what the benefit of using compiled code is?, or can someone give me a reference to look into?.
Thanks in advanced, Patricia B. ______________________________________________ R-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-devel
