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 arguments to be processed by
f(), define it and call it as, for instance using the example above,
f <- function(x, ...) sample(100, 10, ...)
lapply(1:20, f) # the same
lapply(1:20, f, replace=TRUE) # a second argument
See ?lapply
Hope this helps,
