tidy_group_by: Group results by selected columns

In broom.helpers: Helpers for Model Coefficients Tibbles

Group results by selected columns

Description

Indicates that results should be grouped. By default (group_by = auto_group_by()), results will be grouped according to the y.level column (for multinomial models) or the component column (multi-components models) if any.

Usage

tidy_group_by(
  x,
  group_by = auto_group_by(),
  group_labels = NULL,
  model = tidy_get_model(x)
)

auto_group_by()

Arguments

x	(data.frame) A tidy tibble as produced by ⁠tidy_*()⁠ functions.
group_by	(tidy-select) One or several variables to group by. Default is auto_group_by(). Use NULL to force ungrouping.
group_labels	(string) An optional named vector of custom term labels.
model	(a model object, e.g. glm) The corresponding model, if not attached to x.

Value

The x tibble with, if relevant, an additional group_by column.
