help about random generation of a Normal distribution of several variables

Hi, Arnau,

  mvrnorm() in MASS library is what you need.
  ? mvrnorm to see the detail but first you need to load the MASS  
library, i.e,library(MASS)
  regards/

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.
