Hi, I am trying to create a vector of length 10 (say), wherein each element will be average of random sample of size 100, from a distribution, say Normal. Can anyone please tell me without creating a "for" loop, how I can do that?

as a variant of Patrick Burns code, you can write: rowMeans(matrix(rnorm(1000),ncol=100)) ,and substitute another distribution for rnorm if you want. /Gustaf
