is.ggplot

internal

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 http://ggplot2.org for more information,
documentation and examples.
