pmml 2.0.0

With this release, pmmlTransformations has been merged into pmml and package development has been moved to GitHub. This was also a good opportunity to apply a style and rename many functions and parameters to make the code more uniform and easier to understand.

Breaking Changes

We used the tidyverse style guide when renaming functions, parameters, and arguments. In addition, some parameters and arguments have been renamed for clarity, and several functions were removed.

For functions that use a dots (...) parameter, the old parameters will still be accepted, even though these old parameters will not be used.

  • pmml() parameters and default arguments have been changed as follows:

    • model.name = "Rattle_Model" -> model_name = "R_Model"
    • app.name = "Rattle/PMML" -> app_name = "SoftwareAG PMML Generator"
    • unknownValue -> missing_value_replacement

  • Individual exporters had the following changes:

    • pmml.iForest()
      • parentInvalidValueTreatment -> parent_invalid_value_treatment
      • childInvalidValueTreatment -> child_invalid_value_treatment
    • pmml.lm()
      • The unused dataset argument has been removed.
    • pmml.naiveBayes()
      • predictedField - predicted_field
    • pmml.randomForest()
      • unknownValue -> missing_value_replacement
      • parentInvalidValueTreatment -> parent_invalid_value_treatment
      • childInvalidValueTreatment -> child_invalid_value_treatment
    • pmml.xgb.Booster()
      • inputFeatureNames -> input_feature_names
      • outputLabelName -> output_label_name
      • outputCategories -> output_categories
      • xgbDumpFile -> xgb_dump_file
      • parentInvalidValueTreatment -> parent_invalid_value_treatment
      • childInvalidValueTreatment -> child_invalid_value_treatment

  • The following additional functions had name and parameter changes:

    • AddAttributes() -> add_attributes()
      • xmlmodel -> xml_model
    • addDDAttributes() -> add_data_field_attributes()
    • addDFChildren() -> add_data_field_children()
    • addMSAttributes() -> add_mining_field_attributes()
      xmlmodel -> xml_model
    • addOutputField() -> add_output_field()
      • xmlmodel -> xml_model
    • makeIntervals() -> make_intervals()
    • makeOutputNodes() -> make_output_nodes()
    • makeValues() -> make_values()

  • Functions from pmmlTransformations have been merged into pmml and had the following name and parameter changes:

    • All functions had the following parameters renamed where present:
      • xformInfo -> xform_info
      • boxdata -> wrap_object (except in RenameVar)
      • mapMissingTo -> map_missing_to
    • DiscretizeXform() -> xform_discretize()
      • defaultValue -> default_value
      • mapMissingTo -> map_missing_to
    • FunctionXform() -> xform_function()
      • origFieldName -> orig_field_name
      • newFieldName -> new_field_name
      • newFieldDataType -> new_field_data_type
      • formulaText -> expression
    • MapXform() -> xform_map()
      • defaultValue -> default_value
    • MinMaxXform() -> xform_min_max()
    • NormDiscreteXform() -> xform_norm_discrete()
    • RenameVar() -> rename_wrap_var()
      • boxdata -> wrap_data
    • WrapData() -> xform_wrap()
      • indata -> data
      • useMatrix -> use_matrix
    • ZScoreXform() -> xform_z_score()

Deleted/moved functions

  • The following functions have been removed from the package:

    • pmmltoc() - empty function.
    • addLT() - unused function.
    • pmmlCanExport() - unused function.
    • pmml.survreg() - untested exporter that may be added in the future.

  • Initialize() has been made internal.

Other Changes

  • All documentation is created with roxygen.

  • Documentation is now uniform across different exporters.
