default.ahull

Calculate the default alpha parameter for ashape based on the
average size of label boxes.

The directlabels package provides an extensible framework
        for automatically placing direct labels onto multicolor lattice
        or ggplot2 plots. The directlabels package includes heuristics
        for examining "lattice" and "ggplot" objects and inferring an
        appropriate Positioning Method for placing the labels.
        Furthermore, the design of directlabels makes it simple to
        create Positioning Methods for specific plots or libraries of
        portable Positioning Methods that can be re-used.
