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: > > lapp

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 wrote: > 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). > T

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 > > ? replicate > > or a for loop > > or do all one hundred simulations at once > > x <- matrix(rnorm(100^2,

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 wrote: > 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 anyo

? 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 On Sat, Dec 3, 2011 at 1:10 PM, Martin Zonyrah wrote: > Hi, > I need help. I am trying to iterate this command  x <-
