Zane: This has come up several times before on the list, and unfortunately the answer is no - I don't know of any general way to do what you ask. Unless someone else has a solution, I think you'll have to manually split up your lines so they all fit in the map region. If all you lines are in one hemisphere, another potential solution is to use a polar stereographic map (projection = 'npstere' or 'spstere'). That way, you'll be looking down on the earth from above the pole, and the lines will all be within the map (never crossing an edge). > There's this function "addcyclic", but I don't think it does what I > want.
