[Deprecated]

terms_select() has been deprecated in favor of recipes_eval_select().

This function bakes the step function selectors and might be useful when creating custom steps.

terms_select(terms, info, empty_fun = abort_selection)

Arguments

terms

A list of formulas whose right-hand side contains quoted expressions. See rlang::quos() for examples.

info

A tibble with columns variable, type, role, and source that represent the current state of the data. The function summary.recipe() can be used to get this information from a recipe.

empty_fun

A function to execute when no terms are selected by the step. The default function throws an error with a message.

Value

A character string of column names or an error of there are no selectors or if no variables are selected.
