tidy_select_variables: 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))

Value

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

Arguments

x

(data.frame)
A tidy tibble as produced by tidy_*() functions.

include

(tidy-select)
Variables to include. Default is everything(). See also all_continuous(), all_categorical(), all_dichotomous() and all_interaction().

model

(a model object, e.g. glm)
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.
