VietorisRipsComplex: Construct a Vietoris–Rips Complex (1-skeleton + maximal simplices)
Description
Construct a Vietoris–Rips Complex (1-skeleton + maximal simplices)
Usage
VietorisRipsComplex(points, epsilon)
Value
A list with:
network
An igraph object representing the 1-skeleton.
simplices
A list of integer vectors, each the vertex indices of a maximal simplex.
Arguments
points
A numeric matrix or data.frame with one point per row (columns are coordinates).
epsilon
A positive numeric threshold; connect points with distance < \(\epsilon\).
Details
The Vietoris–Rips complex at scale \(\epsilon\) includes a simplex for every
finite set of points with pairwise distances < \(\epsilon\). This function
constructs the 1-skeleton (edges only) and then uses maximal cliques in that
graph as the maximal simplices.
