How Do I profile my functions using DrScheme?

(require profile) 
(define (factorial n)
  (cond
    ((= n 1) 1)
    (else (* n (factorial (- n 1))))))

(profile factorial)

The above code returns

Profiling results
-----------------
  Total cpu time observed: 0ms (out of 0ms)
  Number of samples taken: 0 (once every 0ms)

====================================
                        Caller
Idx  Total    Self    Name+srcLocal%
     ms(pct)  ms(pct)   Callee
====================================

I tried: - (profile (factorial 100))
- (profile factorial) (factorial 100)
But it gives me the same result. What am I doing wrong?

When would you NOT want to use functional programming? What is it not so good at?

Those answers may be correct as of now, but they deal with FP being a new concept (an… >>> More

Does R6RS or Chez Scheme v7.9.4 have a library function to check if a list contains duplicate elements? Alternatively, do either have any built in functionality for sets (which dis-allow duplicate elements)? So far, I've only been able to find an example here. The problem with that is that it doesn't… >>> More
