as.function parameters

Hello,

I'm not completely sure if I understand, but maybe using environments.
If each function copy in the list has a different environment, you can set
the parameters values in that environment.
Something like


f <- as.function(alist(y=,x=tmp,y+x))

env <- list(
	e1=new.env(),
	e2=new.env()
)
fun <- list(
	f1=f,
	f2=f
)

environment(fun$f1) <- env$e1
environment(fun$f2) <- env$e2
env$e1$tmp <- 2
env$e2$tmp <- 4
fun$f1(1)
fun$f2(1)


Also, a code example would be nice, like this I'm just guessing.

Hope this helps,

Thanks for the fast answer..

The problem with your "free" definition of f is, that it does not
really fit my task.

I have to build a tree where each node contains the same function
just with adjusted parameters. Setting the parameters in the function call
is not really an option.

Is there another way to do so?

thanks ahead
