I am a little confused by the question and have two answers depending on what you were asking:

1. You are the only person assigned to your room – it is still a double room. RPI does not change the set up of the room depending on number of people in it.
2. You believe you have a single room – there are currently no single rooms in Warren. Please see point above because you probably were just not assigned another roommate.

If this does not answer your question please resubmit a question that is clearer. Thanks so much!
