new_modeltime_bridge function

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)

Arguments

• 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

Examples

library(dplyr)
library(lubridate)
library(timetk)

lm_model <- lm(value ~ as.numeric(date) + hour(date) + wday(date, label = TRUE),
               data = taylor_30_min)

data = tibble(
    date        = taylor_30_min$date, # Important - The column name must match the modeled data
    # These are standardized names: .actual, .fitted, .residuals
    .actual     = taylor_30_min$value,
    .fitted     = lm_model$fitted.values %>% as.numeric(),
    .residuals  = lm_model$residuals %>% as.numeric()
)

new_modeltime_bridge(
    class  = "lm_time_series_impl",
    models = list(model_1 = lm_model),
    data   = data,
    extras = NULL
)
