[R] Problem with dist (bug?)

Dear list,

using package "proxy".

In one situation, the dissimilarity between two vectors based on 
method=correlation returns a value of 1.9. That should not happen, should it?

The correlation is normally the cos() of the angle between the two vectors 

That dissimilarity

Any clue?

Package dist 0.4-3 on R 2.9.2 on Kubuntu 904 64 bit.
