How to get coefficients at any position (not only regression points) in spgwr?

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 ?t 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,

Dear list,

does anyone knows how to  get coefficients at any position (not only regression points) in spgwr?

I tried to provide a prediction object for the parameter "fit.points" of function gwr(),but it complains "new data matrix rows mismatch " because of  (nrow(predx) != nrow(fit.points)) .
Thanks and best regards,
Chen-Liang Wang
