grof is not mentioned in any of the R manuals, so what are your referring to? (R-admin talks about `to compile a profiling version of R', not of shared libraries.) > I'd very much appreciate pointers as well. You need to use sprof rather than gprof. Here's one relevant thread: http://tolstoy.newcastle.edu.au/~rking/R/devel/05/02/2351.html and I am pretty sure there have been others. Linux has very sketchy info on sprof. However, http://people.redhat.com/drepper/dsohowto.pdf has some.
