Subject: [Rd] dput/dget when a data frame has 2 rows (PR#9627)
Message-ID: <20070423073013.B949A5A7F4@slim.kubism.ku.dk>

It is right.

The problem is that dput() does not give a faithful representation, as its 
help says.  R 2.5.0 does a better job, since the defaults for dput() have 
been changed, enough so that your example works there.
