construct_recipes: Construct a sequence of model recipes for sequential synthesis

Description

Construct a sequence of model recipes for sequential synthesis

Usage

construct_recipes(
  roadmap,
  default_regression_steps = NULL,
  default_classification_steps = NULL,
  custom_steps = NULL
)

Value

A list of formulas

Arguments

roadmap

A roadmap object

default_regression_steps

A list containing one or more recipes::step_*()

default_classification_steps

A list containing one or more recipes::step_*()

custom_steps

A list of lists containing one or more recipes::step_*()

Examples

rm <- roadmap(
  conf_data = acs_conf_nw,
  start_data = acs_start_nw
)

construct_recipes(rm)


# construct_recipes() can create a sequence of recipes using a fully-default 
# approach, a hybrid approach, or a fully-customized approach. All approaches
# require a roadmap and steps. 

rm <- roadmap(
  conf_data = acs_conf_nw,
  start_data = acs_start_nw
)

step1 <- function(x) {
x |>
  recipes::step_center(recipes::all_predictors(), id = "center")
}

# Fully-default approach

construct_recipes(
  roadmap = rm, 
  default_regression_steps = step1, 
  default_classification_steps = step1
)

# Hybrid approach

step2 <- function(x) {
  x |>
    recipes::step_scale(recipes::all_predictors(), id = "scale")
}

construct_recipes(
  roadmap = rm, 
  default_regression_steps = step1,
  default_classification_steps = step1,
  custom_steps = list(
    list(vars = "age", step = step2)
  )
)

# Fully-customized approach

construct_recipes(
  roadmap = rm, 
  custom_steps = list(
    list(vars = c("hcovany", "empstat", "classwkr"), step = step1),
    list(vars = c("age", "famsize", "transit_time", "inctot"), step = step1)
  )
)
