⚠️There's a newer version (3.5.2) of this package.Take me there.

ggplot2 (version 1.0.0)

An implementation of the Grammar of Graphics

Description

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.
