Loops are not massively efficient within R. Look into using the apply() family of functions (eapply()/lapply()/mapply/rapply()/tapply()).
Didn't someone post not too long ago that apply is internally represented as a for-loop? Or am I not remembering this correctly? The reason for apply was that it was more concise but not necessarily more efficient.
