May I say also ask one thing?  @OP: sorry to use your post.

What would you use instead of loops?  I am aware of the apply() functions,
but they are wrapper function of for loops, so they are slower.  At one
point, I was told to go back to C for faster implementation, but I like R
much more.

In the case of repeated simulation such as Monte Carlo, what would you use
instead of for loop?
