[R-sig-Geo] Creating borders.-

[Tom Gottfried]

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.

regards,
Tom
