Hi,

/I think your question should be more relevant on Rdev./
I am not sure that 'print' is called when printing an S4 object. I think 
'show' is used instead.
You might find which methods are usual: 
http://wiki.r-project.org/rwiki/doku.php?id=tips:classes-s4
may help.
Personnally I would find stuff like "names",  "$", "$<-", or "[" useful 
as these are usual operation with S3 objects.

Regards,

Thibaut.
