[Rd] On RObjectTables

[Duncan Temple Lang]

Hi Jeroen

 I am restoring the packages on the Omegahat site as people
ask for them.

 I just put the RObjectTables package up in in its current form at
   http://www.omegahat.org/RObjectTables/
 and am happy to enhance it as needed.

 We can chat off-list, if you want.
