You could also put the call to system.time inside the function itself: f = function(x) { system.time({ ... #function's code ret_val = ... }); flush.console(); return ret_val; }
i s'pose you'd miss out on the time taken to jump to the function code, return the value, etc, but for functions that are heavy at all, that wouldn't trip you up. allie On 5/17/2010 2:06 PM, Barry Rowlingson wrote: > On Mon, May 17, 2010 at 6:24 PM, Peter Ehlers <ehl...@ucalgary.ca> wrote: > > >> Try >> system.time(y <- f(x)) >> >> and see ?"=". >> >> -Peter Ehlers >> > Ah ha.
