1. Do variables sometimes need to be cast in a different way for R to operate correctly, for example, converting from integer to floating point?
2. How does R partition (and how can we tell R to partition) computations across different SPUs so things can execute in parallel? I don’t know if I have the right terminology here, but my understanding is that one of the key values of running R on Netezza is to accelerate processing by running certain functions in parallel.
