Yes, there are a few ways to pan a track in REAPER. Like in Logic, the default pan setting is 'Stereo balance' and not a true stereo pan. To view your options for panning in REAPER, right-click the pan knob on the track that you wish to pan. As you can see, there are options for 'Stereo balance,' 'Stereo balance/mono pan,' 'Stereo pan,' 'Dual pan,' and 'REAPER 3x balance'.
