[R] Efficiency of for-loop in R

2007-12-27 Thread Tong Wang
Hi, I just realized that in Matlab, as long as memory is pre-allocated, doing for-loop doesn't cost more time than doing things in vector form. But it seems in R, it still cost a lot to do for-loop. Is there any improvement in R that I missed. Thanks a lot. Merry Xmas Everyone ! __
