tidy_add_variable_labels: Add variable labels

In larmarange/broom.helpers: Helpers for Model Coefficients Tibbles

Add variable labels

Description

Will add variable labels in a var_label column, based on:

1. labels provided in labels argument if provided;

2. variable labels defined in the original data frame with the label attribute (cf. labelled::var_label());

3. variable name otherwise.

Usage

tidy_add_variable_labels(
  x,
  labels = NULL,
  interaction_sep = " * ",
  model = tidy_get_model(x)
)

Arguments

x	(data.frame) A tidy tibble as produced by ⁠tidy_*()⁠ functions.
labels	(formula-list-selector) An optional named list or a named vector of custom variable labels.
interaction_sep	(string) Separator for interaction terms.
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.

It is possible to pass a custom label for an interaction term in labels (see examples).
