ggplot.ggready: Create a New ggplot for a GGready Data Frame
Description
Creates a new ggplot object for a ggready data.frame.
This is the ggplot() method for class 'ggready';
it tries to implement automatic labels and units in axes and legends
in association with print.ggready_ggplot.
This approach is deprecated in favor of a cleaner
object hierarchy for classes 'decorated' and 'resolved'.
See ggplot.decorated.
