# Data Mining Algorithms In R/Packages/RWeka/Predict Weka Classifier

## Description edit

Predicted values based on fitted Weka classifier models.

## Usage edit

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

## Arguments edit

*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.

## Value edit

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