[R] Mantel test!

Dear Gavin,

What is the interpretation of a simulated p-value of 1 in a mantel  
test and how is the p-value derived?  When we run two highly  
negatively correlated matrices we get this result:  r: -1, simulated p  
value: 1

I would expect the high p-value of 1 to mean not significant.  Could  
you clarify?

Thank you,

Jason
