[R] hash code for arbitrary object

Can anyone suggest a simple way to calculate a 'hash code' from an arbitrary R object?

hash(x) should return an integer or string with the property that

     if hash(x) != hash(y) then x and y are not identical and the time to compute hash(x) should be quite short.

Any suggestions welcome
