A second vignette, vignette("publication-ready-correlation-plots") — a goal-oriented gallery of finished, publication-grade correlogram figures, complementing the argument-by-argument introductory vignette. Motivated by how ggcorrplot is used in the literature (e.g. module-trait heatmaps).

Contents (~8 finished figures, each with copy-paste code):

  • Clustered full correlogram; lower triangle with coefficient labels
  • Significance-masked (blank) and the significance-map (insig="stars")
  • Circle / magnitude-encoded; colorblind-safe palette + custom theme
  • A clean edgeless heatmap (outline.color=NA, reversed red/blue, top-axis labels) — the module-trait / omics-paper look
  • A rectangular predictor-by-outcome matrix (hc.order=FALSE, labels)
  • Full ggplot2 polish (title/subtitle/legend/theme + ggsave at print resolution)

Every figure was rendered and viewed; captions are true of the pixels (fixed one legend-title bug where labs(fill=) didn't override the scale name — use the native legend.title arg). Docs-only, no new dependency; R CMD check --as-cran clean (vignette build + unstated-deps checks OK), pkgdown article builds.
