For the Ricocet, you need to press X & A at the same time, remember your combo counter needs to be yellow to be able to do this move. All the special moves can only be executed when your combo counter is yellow, which happens normally after an 8x combo (or 5x when you have the upgrade from the main game). I think the move you ask about the shocking everyone is the B & A move.
The R button is probably the Right Trigger?
