⚠️There's a newer version (1.5.3) of this package.Take me there.

RgoogleMaps (version 1.2.0.6)

Overlays on Google map tiles in R

Description

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.
