An implementation of the Grammar of Graphics
Hadley Wickham <h.wickham@gmail.com>, Winston Chang <winston@stdout.org>
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.
