Hi Freddy,
from where do you want to extract the information to which spatial
extent you want to interpolate? A shapefile with field borders? You
could also digitalize any polygon with locator(). Anyhow the borders
are not a priori in your data.

Tom

Thanks for your answer, Tom.
Yes, each geodata object is basically a list, and I can add the border
as you mention but, I haven't got these borders. I just have got a
geodata object with coordinates and data but with no borders. My
question is if I can extract or create a border with a object with
these features.
Again, thanks you.

Hi Freddy,
to add borders to an object of class geodata just add them as an
element to
the list (class geodata basically is a list):
obj$borders <- border.polygon
border.polygon here must match coordinates as described in ?
polygon, if I
remember correctly.
