Dear All,

I'm trying to use the gstat code which called Universal Kriging and run the
example in this page


I got some problems hope you can help me to fix it and understand the code

1- when I read the slope file I didn't get the same data structure as in
the example, the  'SpatialGridDataFrame' [package "sp"] with 4 slots instead
of 6 slots

2- thus when I  run the rest of the code I got error messages after trying
to create grid-points overlay

Can any one help me please to fix the problem

Best Regards
