What are the advantages of using STL vectors over STL deque?

This web site has some information on the differences between a vector and deque.

Thanks for the prompt reply. I have already gone through the above link.
However was not able to get any advantage of using vectors over dequeue. So was wondering what could be situation where vectors can be more efficient than dequeue?

the relevant part from the linked page is :
On the drawback side, unlike vectors, deques are not guaranteed to have all its elements in contiguous storage locations, eliminating thus the possibility of safe access through pointer arithmetics.
