text string: xxx-23xz-34L or can be xxx-23exv-24R0

using the formula below, how do I put it such that if it finds an R
than it puts R else if L then it puts L.

IF((MID(G6,FIND("R",G6,1),1))="R","R","L")

trying the OR function but getting confused.

and the FIND({"R","L"}.... doesn't seem to work right.

Thanks for your help
