class RGgdendro(RPackage):
    """This is a set of tools for dendrograms and tree plots using
    'ggplot2'. The 'ggplot2' philosophy is to clearly separate data
    from the presentation. Unfortunately the plot method for
    dendrograms plots directly to a plot device without exposing
    the data. The 'ggdendro' package resolves this by making
    available functions that extract the dendrogram plot data.
    The package provides implementations for tree, rpart, as well
    as diana and agnes cluster diagrams."""
