Dispatch prediction to the correct backend

Detects the model class and calls the appropriate prediction function:

• H2O models : converts newdata to an H2O frame, calls h2o.predict(), extracts the result back to R, then removes the temp frame

• All others : calls predict(model, newdata) via S3/S4 dispatch and coerces whatever shape is returned to a numeric vector

Usage

model_predict(model, newdata)

Arguments

model

A fitted model object (any class).

newdata

A data.table or data.frame of predictor values.

Value

   A numeric vector of predictions, one per row of newdata.
