[R] question about random variable generating function

[xt_wang@cs.concordia.ca]

Hello, everybody,

I have questions about functions in chapter 5: The R API:entry points for c 
code in "writing R Extensions".
They are :

1. double rnorm(double mu, double sigma)
2. double norm_rand()

question is: which of the above two functions can be used to generate a random 
variable of normal distribution?

If norm_rand() is the function, how can I generate random variables whose 
mean=0 and standard deviation=5? As I know, it is used to generate a random 
variable which mean=0,std=1.

I will appreciate very much if anybody can help me.

Thanks in advance!

Maggie
