[R] Iteration in R
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. Can anyone help? Your help is very much appreciated.

Re: [R] Iteration in R
? 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.

Re: [R] Iteration in R
Hi. One approach is using replicate. See ?replicate: replicate(3,rnorm(100,1,2)) Andrija On Sat, Dec 3, 2011 at 7:10 PM, Martin Zonyrah martin20...@yahoo.comwrote: Hi, I need help.

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).

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.

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 bps0...@auburn.edu 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.
