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.

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.

Value

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

NULL, invisibly.

A logical

A character vector
