R help - May 2011 - Bechmarking my code

Dear all,
I have written a quite big piece of code that takes like 6 hourse to execute
(measured that with system.time).

I was wondering if it is possible to try to further understand which are the
pieces of code that are more time consuming so to try to improve them.

Could you please help me understand how I can do this sort of benchmarking?

Best Regards
Alex

Use profiling. See ?Rprof and the manuals to get a first idea.
