Examples of deleteAttributeAt()

org.integratedmodelling.riskwiz.learning.data.Instance.deleteAttributeAt()
Deletes an attribute at the given position (0 to numAttributes() - 1). Only succeeds if the instance does not have access to any dataset because otherwise inconsistencies could be introduced. @param position the attribute's position @throws RuntimeException if the instance has access to adataset
org.integratedmodelling.riskwiz.learning.data.Instances.deleteAttributeAt()
Deletes an attribute at the given position (0 to numAttributes() - 1). A deep copy of the attribute information is performed before the attribute is deleted. @param position the attribute's position (position starts with 0) @throws IllegalArgumentException if the given index is out of range or the class attribute is being deleted
