tidy_select_variables {broom.helpers}

Select variables to keep/drop

Description

Will remove unselected variables from the results. To remove the intercept, use tidy_remove_intercept().

Usage

tidy_select_variables(x, include = everything(), model = tidy_get_model(x))

Arguments

x

a tidy tibble

include

variables to include. Accepts tidyselect syntax. Use - to remove a variable. Default is everything(). See also all_continuous(), all_categorical(), all_dichotomous() and all_interaction()

model

the corresponding model, if not attached to x

Details

If the variable column is not yet available in x, tidy_identify_variables() will be automatically applied.

Value

The x tibble limited to the included variables (and eventually the intercept), sorted according to the include parameter.
