makeGeneticDiversityHeatmap: Make a genetic diversity heat map

Description

Renders a red/yellow/green stoplight heat map of breeding-group genetic diversity metrics. Each row is a breeding group and each column is a metric; every cell is colored by its color index, where 1 is red (the problem condition), 2 is yellow (watch), and 3 is green (healthy).

Usage

makeGeneticDiversityHeatmap(stats)

Value

A ggplot object: a geom_tile heat map with metric headers across the top and group labels down the left, filled red/yellow/green from the color indices.

Arguments

stats

A data frame with one row per breeding group. The first column holds the group label; every remaining column is a metric whose values are color indices in c(1, 2, 3).

Details

This function is agnostic to the number of metric columns: it draws one tile per group-by-metric cell for whatever metric columns it is handed, preserving their input order across the top of the plot.

Examples

stats <- data.frame(
  group = c("Group_1", "Group_2"),
  Value = c(1, 3), Origin = c(2, 3),
  Production = c(3, 2), Inbreeding = c(1, 2)
)
p <- makeGeneticDiversityHeatmap(stats)
