Resolve Label Sizes

Description

Determines label sizes. Default links label cex to node size (qgraph invariant: label.cex is a function of vsize so the node-to-label ratio is locked by construction, and device compensation applied uniformly to both keeps the ratio stable across canvases).

Usage

resolve_label_sizes(
  label_size,
  node_size_usr,
  n,
  scaling = "default",
  visual_scale = NULL,
  node_size = NULL
)

Arguments

label_size	User-specified label size(s) or NULL.
node_size_usr	Node sizes in user coordinates (for legacy coupled mode).
n	Number of nodes.
scaling	Scaling mode: "default" or "legacy".
visual_scale	Optional visual-scale list (from compute_visual_scale). When non-NULL and the caller did not pass label_size, the default label cex is multiplied by visual_scale$scale so label pixel size tracks the output canvas. User-explicit label_size always wins and is returned verbatim — the precedence rule.
node_size	Raw user-supplied node_size (pre-scale-factor). When default (7), yields label cex 1.0 — backward-compatible. When the user doubles node_size, labels double too; when they halve node_size, labels halve. Falls back to the scale constant's node_default when NULL.

Value

Vector of label sizes (cex values).
