r-cran-ggplot2 2.2.1-2 (armhf binary) in ubuntu artful

 ggplot2 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.
