Hello,
and here is another demonstration:

And the 'Assign Closest Airports to Cities' example on this page might
be useful -

Emne: [R-sig-Geo] Smallest distance from one point feature to a pointlayer
Hi All,
I have two shapefiles with point features, A and B. I've managed to
import them into R with maptools and spatstat.
Now I would like to calculate, for each point in A, the closest
distance to any point in B.
What is the best way to do this?
Many thanks in advance,
Gustaf
