[R] how to reproduce the same sampled units?

Hi all,  

Is it possible to generate the same sample number of times in R? In SAS, using the option "seed" it is possible to reproduce exactly the same sample. Is there any such feature in R which I can use?  

For further clarity,  

for (i in 1:2)
{
samp = sample(1:1000,100,replace = FALSE) print(samp)
}  

For the above simulation, is it possible to generate the same sampled units twice?  

Any suggestion would be gratefully acknowledged. Thanks,
Santanu
