Try this: x - c(2,5,9,4,5,6,7,8) u - replicate(20, sample(x, replace = TRUE)) t(u) The first argument of replicate() is the number of times to iterate the process. I believe you'll find that it does indeed do random sampling; each row represents a nonparametric bootstrap sample of x. There are

I am trying to get R to pick random integers from my dataset (i.e. bootstrapping) with replacement. However, my attempts at this have been unsuccessful. Here is a basic example of what I am doing: I have a data vector of 8 integers (data= 2,5,9,4,5,6,7,8). I used the sample function and it
