[R] Iteration in R

2011-12-03 Thread Martin Zonyrah
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.

? 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.

Hi. One approach is using replicate. See ?replicate:

replicate(3,rnorm(100,1,2))

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

Hi Brad. Maybe something like this:

lapply(rep(1,6), function(x) rnorm(10,0,1))

lapply(rep(1,6), FUN=rnorm, n=10, mean=1.0, sd=1)

Re: [R] Iteration in R

2011-12-03 Thread R. Michael Weylandt
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)
