RGB2GRAY

rgb image matrix, usually array with 3 dimensions

myTile

This function translates the rgb values of the array myTile into a scalar matrix with just one gray value per pixel.

This package serves two purposes: (i) Provide a
        comfortable R interface to query the Google server for static
        maps, and (ii) Use the map as a background image to overlay
        plots within R. This requires proper coordinate scaling.
