[R-sig-Geo] about global getis g

[kun17]

Thank you Roger, your professional knowledge has rebuilt my confidence in
spdep.

As to the example, I have a new understanding: when a 'cold spots' was put
in the center, the surrounding grids became 'hot spots' relatively, it
explained the result when distance was set to 1 unit. The idea of 'high' and
'low' in global G is comparative, not measured by mean value.

I will take the example to CrimeStat.

Merry Chrismas everyone!
