[R] Classification tree data structure

I am growing classification trees using the 'tree' package add-on to R.
I would like to convert the 'R' output to the SAS format used by Salford Systems' commercial CART software in order to interface with some
My question is:
How can I parse the R tree data structure in order to infer the tree structure? The 'tree' class has a member '$frame' which gives the splits at
each node, but as far as I can see does not specify the daughter nodes. Is this information accessible through the interface to class 'tree' or
do I need to dive into the C code?
Alternatively, is there an existing add-on which does this? I gather functions exist to read SAS code but I haven't seen anything which writes it.
Thanks in advance,
