R help - Feb 2011 - please hep in uniform distribution

Hi 

I have generate two variable with uniform disrtribution A and B

and I want to calculate the number of cases where B<A^2

So I done it by sum(B<A^2), but I'm not sure if there is anther way to
calculate the number of cases in the distribution or what I have done is
fine 


thanks for helping me 
Woo

What you have done is fine.

You are comparing B[1] to A[1]^2, then B[2] to A[2]^2 etc.  so for the AB pairs
you are doing the comparison.  If that is what you want, then it is fine.

But if you want to compare the 1st B to all the A's, then the 2nd B to all
the A's, etc.  Then it does not do this (but the expand.grid function may
help you.
