IM programs will have ZERO R positions. R positions are only for programs that normally use the match to fill advanced spots, which then have open spots for the year of the match. Since IM only fills PGY-1 spots, they will not use R positions to fill PGY-2 spots (although nothing stops them from doing so, most will simply sign people outside the match).
Anesthesia will have R positions, but they don't need to lock them in until January. Chances are, most programs might not even know they have an open spot yet (since applicants have until January to request a waiver), and even those that do may simply wait to change their quotas until later.
I just logged into the NRMP system, and there are around 35 programs in anesthesia with R positions listed. Most programs have 1 spot. One program has listed 6 spots, and has withdrawn their Advanced match spots. I wonder if this is a mistake, or if they have decided to get out of the Advanced match business and only match R positions.
