Internal Functions

ellipse_check() is deprecated. Instead, empty selections should be supported by all steps.

printer() is used for printing steps.

is_trained() is a helper function that returned a single logical to indicate whether a recipe is traine or not.

sel2char() takes a list of selectors (e.g. terms in most steps) and returns a character vector version for printing.

print_step() is used for printing steps.

Usage

yj_transform(x, lambda, ind_neg = NULL, eps = 0.001)

estimate_yj(
  dat,
  limits = c(-5, 5),
  num_unique = 5,
  na_rm = TRUE,
  call = caller_env(2)
)

ellipse_check(...)

printer(
  tr_obj = NULL,
  untr_obj = NULL,
  trained = FALSE,
  width = max(20, options()$width - 30)
)

is_trained(x)

sel2char(x)

print_step(
  tr_obj = NULL,
  untr_obj = NULL,
  trained = FALSE,
  title = NULL,
  width = max(20, options()$width - 30),
  case_weights = NULL
)

Arguments

x: A list of selectors
...: Arguments pass in from a call to step.
tr_obj: A character vector of names that have been resolved during preparing the recipe (e.g. the columns object of step_log()).
untr_obj: An object of selectors prior to prepping the recipe (e.g. terms in most steps).
trained: A logical for whether the step has been trained.
width: An integer denoting where the output should be wrapped.
title: A character, shortly describing the action the step takes.

Value

ellipse_check(): If not empty, a list of quosures. If empty, an error is thrown.

printer(): NULL, invisibly.

is_trained(): A single logical.

sel2char(): A character vector.

print_step(): NULL, invisibly.
