Ok, I'd like the date an object was saved.  Here's what I used to do in S-PLUS:
 
> dataset.date('my.dataframe')
[1] "Tue May  4 10:16:00 2004"

What do you mean by `a permanently stored version of a dataset'?
If you mean a save()d version, use file.info() on the saved file.

R does not store objects `permanently' as S-PLUS (sic) does, so your exact 
phrasing is meaningless.
