Hi, I need help. I am trying to iterate this command x <- rnorm(100, 1.0, 2.0) one hundred times in R but I don't seem to have a clue.

? 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. Michael

Hi Michael, How would you do this with lapply to return a list? I can't seem to get that to work (I haven't used these much and am trying to learn). Thanks Brad Michael Weylandt 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. Maybe something like this: lapply(rep(1,6), function(x) rnorm(10,0,1)) Andrija On Sat, Dec 3, 2011 at 8:21 PM, B77S <bps0002@> wrote:

And with replicate: replicate(100, rnorm(100, 1,2), simplify = FALSE) Michael

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
