hash code for arbitrary object
You can compute MD5 and SHA1 digests with the 'digest' package. -roger

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
thanks
