Hello I have a loop to draw few samples and I want to but this samples in one list, how I can make this? when I use it , the list show just the last sample. I want to know the correct way to put all samples in one list. Regards Sulafah [[alternative HTML version deleted]]
I would be good if you showed us what you are doing now. There are ways of drawing samples and storing in a list, but we have to see what you are trying to accomplish. You could use 'lapply' or do it in a loop, but the solution would depend on how you are doing things now and what is the problem you are trying to solve.

Tell me what you want to do, not how you want to do it.
Hello, Please read the posting guide: to draw samples from what? A vector? Matrix? Etc... Anyway, here it goes. In all cases the result is a list with 4 elements. # Draw 4 samples of integers from 1 to 10 x <- rep(10, 4) # without replacement set.seed(1) lapply(x, sample, size=6) # with replacement set.seed(12) lapply(x, sample, size=6, replace=TRUE) # # Draw 4 samples from a vector # Make up a vector set.seed(123) (y <- sample(LETTERS, 10)) lapply(1:4, function(i) sample(y, size=6, replace=TRUE)) Hope this helps, Rui Barradas Em 18-06-2012 10:38, solafah bh escreveu:> Hello > I have a loop to draw few samples and I want to but this samples in one list, how I can make this? when I use it , the list show just the last sample.
