[R] Copula in R 2.4.0

[Prof Brian Ripley]

As there is no function normalCopula in R 2.4.0, your example is 
incomplete.  Please see the footer of this message (and perhaps contact 
the maintainer of the package involved).

Please don't send messages repeatedly: if you don't get an answer the 
first time study the posting guide and work out what the problem might be.
