Roger,
Your suggestion:
fullgrid(dem) <- FALSE
did turn dem into class type SpatialGridDataFrame, but when I tried:
z <- predict(UK_fit,newdata=dem)
I got an error:
Error in model.frame(... :
invalid variable type.
I think I should restate the problem:
I have a file 'temps' which has class

Roger,
This got me further along, but I am encountering a problem with:
z <- predict(UK_fit, newdata=BMcD_SPx)
The gstat step works for me, where I have:
UK_fit<-gstat(formula=temps$temp~dem,data=temps,model=efitted)
temps has class SpatialPointsDataFrame:
coordinates cat x
