Right rudder will turn the nose of the plane to the right on the vertical axis(yaw). Doing this will in turn move the actual rudder to the right of the aircraft, forcing the air current to move the tail to the left, moving the nose to the right along this axis. Its like holding a sharpened pencil in the middle of it and saying that you want the pointed end to move right by a certain force exerted on the eraser end...so, you would move the back end left in order to move the pointed end right. Of course, there are more factors to this in the air, duh, but the principle is the same for the question.
Let me know if you have any other questions...I'd love to help.
