Hi Scott,

You may be interested in the ggmap package; see

And, I want to plot to the normal R graphics devices, not the web as package plotGoogleMaps does.  Can anyone provide an example of how to use the result of RgoogleMaps' GetMap.bbox() as a background image in a plot produced with the rasterVis version of lattice graphics?
