[R-sig-Geo] Leader lines for inset map

[Barry Rowlingson]

I don't think you'll get a complete solution from this mailing list until
you tell us how you are drawing your maps in the first place.

Are you using base graphics plotting, or ggplot, or ggmap, or lattice?
Could you throw us a few lines of code that show how you make your base and
insert maps? Otherwise you're going to get a bunch of "just draw lines"
