Direct labels for multicolor plots in lattice or ggplot2
An extensible framework
 for automatically placing direct labels onto multicolor lattice or
 ggplot2 plots.
 Label positions are described using Positioning Methods
 which can be re-used across several different plots.
 There are heuristics for examining "trellis" and "ggplot" objects
 and inferring an appropriate Positioning Method.
