Tena koe Julien I don't use the maps package much, but I suspect par()$usr will allow you to do what you want.

When using the package MAPS, and creating a map, R will automatically adjust the plot to the region that you are plotting. for example the two command: map(regions="Morocco") or map(regions="France") will generate plots with completely different axis and scale. If I want to automatically generate a map and add a legend to it, I would need to be able to retrieve the coordinates of my axis that were automatically generated in order to give coordinate to place my legend on the map. Basically I would like to automatise the following with a function, and be able to automatically get the coordinates for my legend) map(regions="Morocco") map.axes() legend(-12,34, "blablabla") map(regions="France") map.axes() legend(-150,40, "blablabla") mapcountry <- function(country) { map(regions=country) map.axes() legend(xxxx, yyyy, "blablabla") } I want to be able to extract the xxxx and yyyy automatically to be able to generate the legend within the function.
