R help - Aug 2009 - select one function from two of them in another function

Hi all,      I have two functions called test1() and test2(). Now how do I
select one of them in test3()??

Say
  test3<-function(func="test1"){
        if (func=="test1"){
               now.func<-test1()
       }
       else now.func<-test2()
 }

I know this function I wrote does not right. Do anyone can tell me how to do
that for real?

Thanks a million

S.H.

Is this what you want -- this returns a function that you can then call:
> test1 <- function() 1
> test2 <- function() 2
> test3 <- function(func='test1'){  # return the function to call
+     if (func == 'test1') return(test1)
+     return(test2)
+ }
>
> # test it
> test3()()  # default -- notice the second set of parens
[1] 1
>
> test3('test1')()
[1] 1
>
> test3('test2')()
[1] 2
