Overlaying shapefiles or raster over interactive maps
问题 I'm using R, and I want to overlay some raster data (e.g. a temperature map from a model) over an interactive map which allows panning and zooming. Ideally, I'd like to overlay over Google Maps or OpenStreetMaps. The input data can be in shapefiles, KML, raster data or whatever comes in handy. I know I can easily do this non-interactively using either googleVis , ggmap or RgoogleMaps . But I do not want to use tiles, I want interaction ! Zooming, panning etc., directly from the browser.
