[R] Using if statement on function

Hello everybody,

I'm trying to use a if-statment on a function. For a better understanding I want to present a small example:

    FUN=mean                             # could also be median,sd or 
any other function

    if (FUN == mean)

       plot(...)
    if (FUN == median)

       plot(...)
    ...

This doesn't work, because FUN is a function. I've already tried to coerce the type of FUN with as.character( ), but that's also not possible. I'm stuck with this task and it is absolutely necessary to give FUN the class of a function.
I'm looking forward for any hints, clues or solutions for my problem.

So much thanks in advance

Etienne
