The DatasetRef class is used not only to create a reference to a dataset but also to initially create a dataset.

A DatasetRef can be initialized as a class with the name of the dataset a parameter, or using the rgg library function dataset(“DS_name”). If no dataset with this name exists an empty one is created.

To delete all data from a dataset using rgg:

dataset("DS_name").clear();

dataset("DS_name").addRow().set(0,11.4).set(1,23.5);
dataset("DS_name").addRow().set(0,18.2).set(1,2.73);
