hi.
i'm a statistics student and studying bootstrap in R.

i'm trying to draw bootstrap samples from a sample, using the following R
code:

> *boot = numeric(200)*
*> {for (i in 1:200)*

*  boot [i] = (sample(data,replace=T))}*



i obtain 200 samples but all of them are the same.

i want to obtain different samples. what should i do? can you please help me
if possible.



thank you.
