An implementation of the grammar of graphics in R. It
        combines the advantages of both base and lattice graphics:
        conditioning and shared axes are handled automatically, and you
        can still build up a plot step by step from multiple data
        sources. It also implements a sophisticated multidimensional
        conditioning system and a consistent interface to map data to
        aesthetic attributes. See the ggplot2 website for more
        information, documentation and examples.

fortify.sp: Fortify method for classes from the sp package.
