Compare Function Values of Retained Extrema at Different Thresholds

Shows the actual extrema (with their function values) that would be retained at different threshold choices. Helps assess whether retained extrema make biological/domain sense.

Usage

# S3 method for class 'retained.extrema'
compare(extrema_df, thresholds = c(2, 3, 4, 5), sort_by = "hop_idx")

Arguments

extrema_df: Data frame with vertex, hop_idx, value, label columns
thresholds: Vector of thresholds to compare
sort_by: Character; how to sort results ("hop_idx", "value", or "vertex")

Value

List of data frames, one per threshold

Examples

extrema_df <- data.frame(
  vertex = 1:5,
  hop_idx = c(1, 3, 5, 7, Inf),
  is_max = c(0, 1, 0, 1, 1),
  label = c("m1", "M1", "m2", "M2", "M3"),
  value = c(0.2, 1.3, 0.4, 1.6, 2.0)
)
retained <- compare.retained.extrema(
  extrema_df,
  thresholds = c(2, 4),
  sort_by = "value"
)
