random number generator

I have an inquire about the RNG in R

It is known that when we use the " rnorm " function , we pass the
arguments :

1- number of variables to be generated
2- mean vector of the normal random errors.
3- standard deviation vector of the normal random errors.

my question is the following

Is the a way (a function) in R that we could specify the covariance
matrix in step 3, instead of the

standard deviation vector of the normal random errors, since we want to
generate multivariate

correlated random data.

many thanks
