Constructor for creating modeltime models
These functions are used to construct new modeltime bridge functions that
connect the tidymodels infrastructure to time-series models containing date or date-time features.
new_modeltime_bridge(class, models, data, extras = NULL, desc = NULL)
class |
A class name that is used for creating custom printing messages |
models |
A list containing one or more models |
data |
A data frame (or tibble) containing 4 columns: (date column with name that matches input data), .actual, .fitted, and .residuals. |
extras |
An optional list that is typically used for transferring preprocessing recipes to the predict method. |
desc |
An optional model description to appear when printing your modeltime objects |
