Additional functions

The following functions in pmml allow additional operations, such as creating specific nodes and adding attributes. For more information, check the documentation for each function.

• AddAttributes: add attribute values to an existing element in a given PMML file.
• AddDDAttributes: add attribute values to an existing DataField element in a given PMML file.
• addDFChildren: add ‘Interval’ and ‘Value’ child elements to a given DataField element in a given PMML file.
• addLT: add a LocalTransformations element to a given PMML file.
• addMSAttributes: add attribute values to an existing MiningField element in a given PMML file.
• addOutputField: add Output nodes to a PMML object.
• fileToXMLNode: read in a file and parse it into an object of type XMLNode.
• functionToPMML: convert an R expression to PMML.
• makeIntervals: create Interval elements to add to a DataDictionary element.
• makeOutputNodes: add Output nodes to a PMML object.
• makeValues: create Values element to add to a DataDictionary element.
