exp_dataset(ent_type = exp_entityType())
exp_dataFrame(ent_type = exp_entityType())exp_dataset, a GGobi dataset, see rggobi documentation.
For exp_dataFrame, a data.frame coerced from the result of
exp_dataset.
exp_dataset allows one to directly
manipulate the GGobi dataset. If only a data.frame is required,
exp_dataFrame is a more convenient path.
