[R] help about random generation of a Normal distribution of several variables

[Arnau Mir Torres]

Hello.

Somebody knows how can I generate a set of n random vectors  of a  
normal distribution of several variables?
For example, I want to generate n=100 random vectors of two dimensions  
for a normal with mean c(0,1)  and  variance matrix:   
matrix(c(2,1,1,3),2,2).

Thanks in advance,

Arnau.
