Psych grad student here, R user for 3 years. Using R for experiments  
is likely not advisable as it has no fine control of display timing  
(ex synching stimuli to the screen refresh, etc). On recommendation  
of colleagues I'm learning the Python language, which has a module  
called 'pygame' that is fantastic for psych experiments.
