Resolve Donut Parameters

Description

Normalizes donut/pie overlay parameters into the canonical format expected by render_nodes_splot(). Handles donut_fill auto-enable, list conversion, empty-value NA replacement, color encoding (1/2/n-color), shape inheritance, and border vectorization.

Usage

resolve_donut_params(
  donut_fill,
  donut_values,
  donut_color,
  donut_colors,
  donut_bg_color,
  donut_shape,
  donut_border_color,
  donut_outer_border_color,
  donut_line_type,
  donut_empty,
  shapes,
  n_nodes
)

Arguments

donut_fill	User-specified donut fill values.
donut_values	Raw donut values (deprecated path).
donut_color	Donut color specification (1, 2, or n colors).
donut_colors	Deprecated donut colors (list).
donut_bg_color	Background color.
donut_shape	Donut base shape override.
donut_border_color	Border color.
donut_outer_border_color	Outer border color.
donut_line_type	Line type.
donut_empty	Logical: render empty rings?
shapes	Resolved node shapes vector.
n_nodes	Number of nodes.

Value

Named list of effective_* parameters.
