Thank you very much, this certainly helps.
I'm still curious, though, to know how to
write the expression of my function
immediately as the argument f.
I can define it outside of the function
> aap <- function(x) -x^3
and use it as argument
> iterate(aap,3,256),
but I seem not to be clever enough
to write a function that receives
the following as input
> iterate(-x^3,3,256)
Thanks again,
Tobias
