R/Weka Classifiers

Description

R interfaces to Weka classifiers.

Details

Supervised learners, i.e., algorithms for classification and regression, are termed “classifiers” by Weka. (Numeric prediction, i.e., regression, is interpreted as prediction of a continuous class.)

R interface functions to Weka classifiers are created by make_Weka_classifier, and have formals formula, data, subset, na.action, and control (default: none), where the first four have the “usual” meanings for statistical modeling functions in R, and the last again specifies the control options to be employed by the Weka learner.

By default, the model formulae should only use the + and - operators to indicate the variables to be included or not used, respectively.

See model.frame for details on how na.action is used.

Objects created by these interfaces always inherit from class Weka_classifier, and have at least suitable print, summary (via evaluate_Weka_classifier), and predict methods.

Available “standard” interface functions are documented in Weka_classifier_functions (regression and classification function learners), Weka_classifier_lazy (lazy learners), Weka_classifier_meta (meta learners), Weka_classifier_rules (rule learners), and Weka_classifier_trees (regression and classification tree learners).
