plot.grass_card: Plot a 'grass_card' Report Card object

In grassr: Context-Conditioned Reporting for Binary Rater Reliability

Plot a grass_card Report Card object

Description

Six views of a Report Card returned by grass_report(). The default "surface" view places the study on its DGP-calibrated reference surface; the other views are for cross-coefficient comparison, the asymmetry diagnostic, observed-coefficient confidence intervals, per-rater Se/Sp from the latent-class fit (only valid when card$delta$flag == "divergent"), and a patchwork composite of the most useful at-a-glance panels.

Usage

## S3 method for class 'grass_card'
plot(
  x,
  type = c("surface", "panel", "thermometer", "intervals", "per_rater", "pairwise",
    "diagnostic"),
  ...
)

Arguments

x	A grass_card object.
type	One of: "surface" (default) – 2D heatmap of the expected primary metric over (M_1, q) at the study's (k, N), with the observation pinned and dotted band contours at q in {0.5, 0.625, 0.75, 0.875, 1.0}. "panel" – forest plot of all panel coefficients on the percentile axis (0-100), so the cross-coefficient spread is visible. "thermometer" – colored gauge for delta_hat with the aligned/caution/divergent thresholds shown. "intervals" – forest plot of observed coefficients with 95% Wilson-logit CIs. "per_rater" – forest plot of per-rater Se-hat and Sp-hat (latent-class bootstrap CIs). Errors when card$per_rater is NULL. "pairwise" – k x k tile heatmap of pairwise surface percentiles (cell label = percentile; parenthetical label = PABAK_ij). Only available when card$delta$flag == "divergent" (auto-populated by grass_report() via pairwise_agreement()). "diagnostic" – patchwork composite of "panel" + "thermometer" + "pairwise" (under divergent) / "per_rater" / "intervals".
...	Currently unused.

Value

A ggplot object (or a patchwork composite for type = "diagnostic").
