I'm still getting used to R's scoping. I've run into the following situation

thefunction <- function() print( value ) somefunction <- function() { value=99; thefunction() } somefunction()

now, I understand that somefunction() returns 0 because thefunction() was defined with value=0 in its parent envrionment, it dosent look at all in the environment of somefunction. My question is can I re-scope thefunction in the somefunction environment?? (So that somefunction() returns 99). I've tried various uses of eval() and assign() with their keywords in the definition of somefunction and have had no luck at all.

I do see that i could define thefunction in some external file and source it inside somefunction, but that seems clumsy.
