rnaturalearth: detail by degrees
Hi Ferri, One way is to snip out a Google Maps image of the area you want, then using the "maps" package, start a plot bounded by the corner coordinates of your Google Maps image. You can get those by clicking on the corners of the area that you selected. Then use the "readbitmap" package to create a raster object of your GM image and display it on the plot made by "map". Finally, use either "points" or "lines" to display the coordinates of your path. Jim

Dear all, I have the graph of a path, walking a number of places specified by name, logitude and latitude ? thanks to Don MacQueen. xliam and ylim define a certain section of the earth. How can I put this section of a political map into the background? Thank you in advance. Yours, Ferri
