zoom

The function LatLon2XY.centered(MyMap, lat,lon,zoom) computes the coordinate transformation from lat/lon to map tile coordinates given a map object.

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.
