No, but you should be able to tell Windows to run it at a lower 
priority.  Open the Task Manager, select R among the applications and 
then use the right mouse button to "Go To Process" (or just select it 
among the processes), then use the right mouse button to set priority to

"below normal" or "low".  I'm not sure what privileges you need to do 
this; it's possible you may need to do it as an admin.
