[R-sig-Geo] using gwr for interpolation

[Edzer Pebesma]

Can I use gwr for interpolation?

I would for example use something like

library(spgwr)
data(meuse)
coordinates(meuse) = ~x+y
data(meuse.grid)
gridded(meuse.grid) = ~x+y
x = gwr(cadmium ~ dist, meuse, bandwidth = 228, fit.points = meuse.grid)
spplot(x$SDF["gwr.e"])

But it doesn't give what I'd expected - somehow nicely interpolated
cadmium values. I probably misused fit.points, but I couldn't see any
predict method. Is this possible at all?
