[GRASS-user] kriging with GRASS 6.2 and R

[Dr. Manuel Seeger]

Hallo all,

I'm trying to generate a DEM with kriging and trying the workout given 
in the wiki.
When generating the R SpatialGridDataFrame I get this error:
Fehler in validObject(.Object) : invalid class "SpatialGridDataFrame" 
object: invalid object for slot "data" in class "SpatialGridDataFrame": 
got class "list", should be or extend class "data.frame"

I know, its not really a GRASS issue, but perhaps someone can help, what 
I'm doing wrong!

Thanks

Manuel
