Calculate Intraspecific Pairwise Colony Distances as sf LINESTRINGs — calculate_intraspecific_allee

Computes intraspecific pairwise distances between coral colony centroids and derives edge-to-edge and maximum distances. Results are returned as sf LINESTRINGs connecting colony centroids.

Usage

calculate_intraspecific_allee_dist(subset, label, ...)

Arguments

subset: An sf object with polygon geometries, and columns species, id, and width (diameter in cm).
label: A character label (e.g. "bleached", "unbleached") to annotate each line.

Value

An sf object of LINESTRINGs with columns:

species: Species name.
id_from: ID of origin colony.
id_to: ID of target colony.
centroid_distance: Distance between colony centroids (in CRS units).
colony_distance: Edge-to-edge distance (centroid distance minus radii).
max_distance: Maximum distance including both radii.
status: Label passed to label argument.

Examples

if (FALSE) { # \dontrun{
calculate_intraspecific_allee_dist(coral_sf, label = "unbleached")
} # }
