Generate edge information

This function generates edge information from a given triangular object, including the coordinates of the vertices and the from-to relationships between the vertices.

Usage

gen_edges(tri_object, threshold = 0)

Arguments

tri_object

The triangular object from which to generate edge information.

threshold

A numeric value to filter high-density hexagons.

Value

A tibble that contains the edge information, including the from-to relationships and the corresponding x and y coordinates.

Examples

tr1_object <- s_curve_obj$s_curve_umap_model_tr1_object
gen_edges(tri_object = tr1_object)
