The predict() function computes predictions from each of the
models in the ensembles and returns a single aggregated value
for each sample in new_data.
Usage
# S3 method for bagger
predict(object, new_data, type = NULL, ...)Arguments
- object
An object generated by
bagger().- new_data
A data frame of predictors. If a recipe or formula were originally used, the original data should be passed here instead of a preprocessed version.
- type
A single character value for the type of predictions. For regression models,
type = 'numeric'is valid and'class'and'prob'are valid for classification models.- ...
