[R-sig-Geo] krig.image beyond data points

[Paul Hiemstra]

Dear Micheal,

I think you can also use the spplot command. It is not present in the 
gstat package but in the sp package. The most recent version of gstat 
(0.9-34)  needs sp present, so I think you already have this package. 
For more info on spplot use:

?spplot

I think that the ylim and xlim options will suit your needs, just 
overwrite the default values (xlim = bbox(obj)[1, ], ylim = bbox(obj)[2, ]).

hth,

Paul

Is there a way to force krig.image to extrapolate just a little beyond the range of the data points? Thank you for any suggestions.
