Problems with randomly generating samples

Dear R users,
Can anyone please tell me how to generate a large number of samples in
R, given certain distribution and size.
For example, if I want to generate 1000 samples of size n=100, with a
N(0,1) distribution, how should I proceed? 
(Since I dont want to do "rnorm(100,0,1)" in R for 1000 times)
 
Thanks for help
Debbie

One possibility is

  nsamples <- 1000
  sampsize <- 100
  Samples <- matrix(rnorm(nsamples*sampsize,0,1),nrow=nsamples)

Then each row of the matrix Samples will be a sample of size 'sampsize',
the i-th can be accessed as Samples[i,], and there are 'nsamples' rows
to choose from.

Ted.
