orbital_r_fun: Turn orbital object into a R function

In orbital: Predict with 'tidymodels' Workflows in Databases

Turn orbital object into a R function

Description

Returns a R file that contains a function that output predictions when applied to data frames.

Usage

orbital_r_fun(x, name = "orbital_predict", file)

Arguments

x	An orbital object.
name	Name of created function. Defaults to '"orbital_predict"“.
file	A file name.

Details

The generated function is only expected to work on data frame objects. The generated function doesn't require the orbital package to be loaded. Depending on what models and steps are used, other packages such as dplyr will need to be loaded as well.

Value

Nothing.

Examples

library(workflows)
library(recipes)
library(parsnip)

rec_spec <- recipe(mpg ~ ., data = mtcars) %>%
  step_normalize(all_numeric_predictors())

lm_spec <- linear_reg()

wf_spec <- workflow(rec_spec, lm_spec)

wf_fit <- fit(wf_spec, mtcars)

orbital_obj <- orbital(wf_fit)

file_name <- tempfile()

orbital_r_fun(orbital_obj, file = file_name)
