You can also click F2~F5. If you look left in the upper corner while playing you see the portraits of your allies. F2 for the most upper ally and F5 for the lowest ally, and of course F3 and F4 for the ones in the middle. F1 is for yourself.

So in short. Hit the R key and then F2 will ultimate the first ally of the portraits.
