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.
