The simplest if you just type R or R1 or R2 and you will get an R, R1, R2 atom correspondingly.Many abbreviated groups are also available in this way, try typing Tos, Ph or ring10 for example. R-atoms are also available in the right-click pop-up menu on an atom. They can be specified from the buttons of the Advanced page of the Periodic System as well, but that location is probably the least convenient.
