Hi folks: could anyone give me some hints about plotting timezones grid using polygons over the world map in R? I use maps to get the world layout, but where to get coordinates of timezones polygons?
Ultimately, I would love to get something like this, coloring timezones according to some values from my analyses. Thank you!
If your question is just where to get time zone shapefiles for plotting, then you can get some from http://efele.net/maps/tz/world/.
