If you're going to use a version which is that antiquated
then you can expect a great many things not to work.
Version 2.10.1 is about to be released, for crying out loud!
Are are package installations backward compatible?
Mostly.
Will R code that works in order installations work in the new
installations?
Mostly.
R-core go to a great deal of effort to make new releases backward
compatible and to make sure that old code doesn't get broken.
Sometimes, however, there's just no help for it, and things get
broken. Usually there are plenty of warnings in the ``news'',
and the breaks can of course always be fixed. This is R, after all.
cheers,
Rolf Turner

Here is my sessionInfo(). BTW, it is generally not a good idea to top
post in mailing list or newsgroup, because it breaks the message flow.

No documentation for 'anyDuplicated' in specified packages and libraries:
you could try 'help.search("anyDuplicated")'

See ?duplicated.
