I have inherited a legacy S-plus system with about 10,000 lines of S and 10,000 lines of Fortran. It's now running under R. However, I would like to profile the fortran code with gprof or prof for performance tuning. I've successfully linked the .so file into a simple C driver program and profiled, but I can't seem to get profiling to work when using dyn.load() to use it from R. Do I have to use .C() to call some monitor initialization procedure explicitly? The /var/tmp/foo.so.profile file is never created.
I'm using R 1.6.2 and I have the same problem under both SunOS 5.8 and under Red Hat Linux 7.3 with 2.4.18-openmosix4smp kernel. Has anyone had any success with this sort of profiling?
