Add values to a biomarker performance heatmap — add_biomarker

Adds numeric cell labels to the heatmap returned by ScreenBiomarkerPerformance(). This helper is intended for downstream annotation of SciDataReportR biomarker heatmaps while keeping the default heatmap uncluttered and hover-friendly.

Usage

add_biomarker_values(
  plot,
  value_var = "HeatmapValue",
  digits = 2,
  size = 3,
  color = "black"
)

Arguments

plot: A biomarker heatmap ggplot, typically ScreenBiomarkerPerformance(...)$Plots$Heatmap.
value_var: Column in plot$data used for labels. Default is "HeatmapValue".
digits: Number of decimal places. Default is 2.
size: Text size. Default is 3.
color: Text color. Default is "black".

Value

A ggplot with numeric values added to each non-missing heatmap cell.

Examples

if (FALSE) { # \dontrun{
screen$Plots$Heatmap %>% add_biomarker_values()
} # }
