yj_transform: Internal Functions

Description

These are not to be used directly by the users.

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

This internal function is used for printing steps.

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

This internal function 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)
ellipse_check(...)
printer(
  tr_obj = NULL,
  untr_obj = NULL,
  trained = FALSE,
  width = max(20, options()$width - 30)
)
prepare(x, ...)
is_trained(x)
sel2char(x)
print_step(
  tr_obj = NULL,
  untr_obj = NULL,
  trained = FALSE,
  title = NULL,
  width = max(20, options()$width - 30),
  case_weights = NULL
)

Value

If not empty, a list of quosures. If empty, an error is thrown.

NULL, invisibly.

A logical

A character vector

NULL, invisibly.

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.
