> Dear David,
Dear R users,
Now R calculates var1.pred as a constatnt:
kriged=krige(Nmin~1,locationsDD,grid,model=fit)

> kriged["var1.pred"]

spplot(kriged["var1.pred"])
 Error: unexpected string constant in:
"
spplot(kriged[""

And it cann't give ssplot
Please if anyone can help me!


I was getting this error as well.  The cause was either not having the
> coordinates and coordinate reference system (CRS) set or having the wrong
