The saved structure is essentially a list of functions and arguments to 
be called in sequence.  Some of the functions take different arguments 
in different R versions.  There are likely also different behaviours for 
the same arguments in other cases.

The only real documentation on this is in the source code.

A safer strategy to achieve what you want to do is to save the code and 
data that produced each plot.  Then at least if functions change you can 
edit your saved copy and still get a plot.
