[R] Problem with dist (bug?)

here is the code that generates the problem:
is 1.9. I do not think it should be, because the value is usually the cos() of
the angle between the 2 vectors. If you use method="cosine" you have 1.8,
which I think it should not be.
Is there a problem with the way I use it, or is there a bug?
I have been able to reduce the scot.csv to under 200MB, but I thought of not
posting it to the list ....
