Plot sensitivity heatmap for SPR outputs — plot_sensitivity

Heatmap based on spr_sensitivity() output for a two-parameter sweep with the base values overlayed. Uses viridis by default when available.

Usage

plot_sensitivity_heatmap(
  sens_df,
  x,
  y,
  fill,
  facet = NULL,
  title = NULL,
  fill_scale = c("viridis", "base"),
  base_marker = TRUE,
  base_point_size = 5,
  base_point_color = "#D55E00",
  base_point_stroke = 1.4,
  base_label = FALSE
)

Arguments

sens_df: Data frame returned by spr_sensitivity().
x: Name of the column to use for the x-axis (character).
y: Name of the column to use for the y-axis (character).
fill: Name of the column to use for tile fill (character).
facet: Optional column name to facet by (character).
title: Optional plot title.
fill_scale: Character, either "base" or "viridis" (default).
base_marker: Logical. If TRUE, overlays a base-case marker when base values are available.
base_point_size: Numeric, size of base case mark (X).
base_point_color: Outline color for base case mark, defaults to a colorblind-friendly orange.
base_point_stroke: Stroke width for base case mark.
base_label: Logical. If TRUE, labels the base marker with "Base".

Value

A ggplot object.

Details

This function is intended for visualization of structured parameter sweeps where x and y are numeric columns in the sensitivity table and fill is a numeric output (for example "F40_total", "F40_total_constrained", "YPR_at_F40", or "plus_share_RE_Ftarget").

Examples

if (FALSE) { # \dontrun{
# Heatmap of unconstrained F40 across (M, a50)
plot_sensitivity_heatmap(out, x = "M", y = "maturity_a50", fill = "F40_total")
} # }
