compute_pd: Compute persistent diagram from point cloud.

In hosscine/phacm: The R Package for Analyzing Persistent Homology and Cycles of Manifold

Description

Uses TDA::ripsDiag() to compute persistent diagram. Then keeps diagram to avoid to recomputing. The keeped diagram can be took out by last_pd().

Usage

compute_pd(X, maxdimension, maxscale)

Arguments

X	target data.
maxdimension	max dimension to compute. Lower value makes computatin time to short. In case of computing on the general computer, 'maxdimension = 1“ is recomended firstly to avoid freeze your computer.
maxscale	max scale to compute.

Value

persistent diagram.
