Re: [R] Iteration in R
Because lapply() tries to pass an argument to FUN and there's none that it can receive. This would work however: lapply(rep(100, 6), rnorm, mean = 1, sd = 2) Michael On Sat, Dec 3, 2011 at 2:42 PM, B77S wrote: > Interesting and thank you; I'm confused as to why this doesn't work with: > > lapply(rep(1,6), FUN=rnorm, n=10, mean=1.0, sd=1) > > > > andrija djurovic wrote >> >> Hi Brad.

? replicate or a for loop or do all one hundred simulations at once x <- matrix(rnorm(100^2, 1, 2), 100) It's going to depend on what you want to do with the numbers.
