Hi All, I have a few queries regarding Random Number generation in R. according to the help(Random.User) i defined my own functions for user_unif_rand and user_norm_rand (uniform and normal distribution)But what i figured out was even when i call rexp,rpois,rgeom and other distributions they were routed via user_unif_rand. 1. Does this mean that for all types of distribution it generates an Uniform distribution and transforms to the requested type? Also surprisingly even rnorm which i hoped to route via user_norm_rand was calling user_unif_rand...rnorm(1)inside user_unif_rand//printf and inside user_unif_rand [1] 0.5973648 Please help me out understanding this... 2. Our goal is to link with an vectorized Random number generator library for our multi-core architecture. So is it enough if we define user_unif_rand function alone and will it take care of all distributions? Thanks in Anticipation, R.
