[R-sig-Geo] How to get coefficients at any position (not only regression points) in spgwr?

[Danlin Yu]

Chen-Liang:

Did you check on your fit.points object? It shall be a new set of 
coordinates that you intend to do prediction upon. According to the 
online help manual, the fit.points object shall be "an object containing 
the coordinates of fit points; often an object from package sp; if 
missing, the coordinates given through the data argument object, or the 
coords argument are used."

Hope this helps.

Cheers,
Dr. Danlin Yu
