Dear all, good morning,
I have a population, let say members are tagged with some simple
number like
1,2,3,...20. I want to draw a sample with replacement of size 4
(say, can be
more than 20 also).
Already answered on the list.
Is there any R function which will show me all such
possible samples?
?expand.grid
> nrow(expand.grid(1:20, 1:20, 1:20, 1:20))
