I am trying to get R to randomly select values 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 values (i.e. data= 2,5,9,4,5,6,7,8).  I used the
sample function and it worked.  However, it only repeated my values in the
exact same order as the dataset.  It did not randomly sample them.  Here the
code for what I did:  

sample(data, replace=TRUE)

Any advice to randomly select data from my dataset would be greatly
appreciated.
