  1. I have no experience in dynamic programming (so you may want to ignore the rest of this message)
  2. Your message is vague (to me) -- more specifics about what you want to do might result in a better answer.
  3. R has become **much** better at loop management since 2002
  4. Nevertheless, there are undoubtedly still situations where R may require an unacceptably large amount of memory overhead. Recursion is one, I believe.

Usually the best advice is: try it and see.
