I found this to be quite the challenge also. See pg_tuple_get_r_frame() 
in the file pg_conversion.c from PL/R. You can grab a copy here:

If you have any questions after looking through that, contact me off 
list and I'll try to help. That said, there's no guarantee my code is 
correct, but at least it seems to work in all of my use-cases so far ;-)
