< Data Mining Algorithms In R‎ | Packages‎ | RWeka


Predicted values based on fitted Weka classifier models.


predict(object, newdata = NULL, type = c("class", "probability"), ...)


object, an object of class inheriting from Weka_classifier. newdata, an optional data frame in which to look for variables with which to predict. If omitted or NULL, the training instances are used. type, character string determining whether classes should be predicted (numeric for regression, factor for classification) or class probabilities (only available for classification). Further arguments passed to or from other methods.


Either a vector with classes or a matrix with the posterior class probabilities, with rows corresponding to instances and columns to classes.
