Re: [R] how to profile R interpreter?
Thanks for your quick reply, David. Let me make myself more clear. I tried Rprof, which only gives profiling information at script level. My intention is to identify hot spots in R interpreter. I compiled R interpreter with -pg for gprof. However, I couldn't generate gmon.out when I ran the R interpreter with a script.

My intention is to identify hot spots in R interpreter. I compiled R interpreter with -pg for gprof. However, I couldn't generate gmon.out when I ran the R interpreter with a script. Could this possibly be handled better in R-devel? Doesn't sound like typical R usage.
