  model_version = NULL,
  transforms = NULL,
  missing_value_replacement = NULL,
  parent_invalid_value_treatment = "returnInvalid",
  child_invalid_value_treatment = "asIs",
  ...
)

Arguments

model: A randomForest object.
model_name: A name to be given to the PMML model.
app_name: The name of the application that generated the PMML.
description: A descriptive text for the Header element of the PMML.
copyright: The copyright notice for the model.
model_version: A string specifying the model version.
transforms: Data transformations.
missing_value_replacement: Value to be used as the 'missingValueReplacement' attribute for all MiningFields.
parent_invalid_value_treatment: Invalid value treatment at the top MiningField level.
child_invalid_value_treatment: Invalid value treatment at the model segment MiningField level.
...: Further arguments passed to or from other methods.

Value
