Hello, You can avoid the loop using lapply. f <- function(x) sample(100, 10) samp.list <- lapply(1:20, f) will choose 20 samples of 10 integers up to 100 and put them in a list. All you need is to write a function f(). f() must have an argument, even if it doesn't use it. If you need other ar

Instead of a loop you can use the replicate or lapply functions which will create lists for you. otherwise you can start with an empty list (mylist <- list() ) then add to the list in each iteration of the loop: for(i in 1:10) { mylist[[i]] <- myfunction(i) } On Sat, Jun 30, 2012 at 1:34
