Makes multiple predictions on test set using resampled variations of data set. Uses randomForest as the weak classifier and expects a multinomial character outcome variable. Returns a final test set prediction with each forest having an equal vote. Implementation of Breiman's ensemble bagging classifier as described by Obitz & Maclin (1999).

formula |
A formula expression for the classifier model. Expects the form outcome ~ predictors with a single outcome variable. The outcome variable is expected to be of type character. |
data |
A data frame consisting of the training data set. Must include all variables described in the formula including the outcome variable. |
test |
A data frame consisting of the test set to be predicted. Must include all predictor variables. May include outcome variable. |
m |
Number of classifiers to vote on final prediction. Defaults to 5. |
ntree |
Number of trees for each randomForest to grow. Defaults to 500. |
mtry |
Number of variables randomForest randomly samples as candidates at each split. Defaults to the square root of the number of variables in data. |
trace |
Setting for randomForest do.trace. Defaults to TRUE. |
Character vector consisting of a final prediction for each test set sample.
