Hi Rolf,

I have a similar question. I want to test whether a point with certain
coordinates is inside 
a state, say Texas. It seems that inside.owin() only works for testing if a
point lies in a
regular region, say a polygon. Since Texas has irregular boundary, how do we
achieve this?
Or there is some alternative way we can use.
