Adding Two-Headed Arrow in map legend
Hi Milu, I just realized that by "the bottom of the map" you may mean "beneath the map", in which case you should use: par(xpd=TRUE) arrows(...) par(xpd=FALSE) Jim

Dear David,
Thank you very much for your replies! I didn't know about par('usr').
I get different coordinates though:
[1] -19.75966 54.75966 33.60000 71.40000
But the arrow is not at the bottom of the map. I will keep playing with
this. Thanks again!
Sincerely,
Milu
