create_clusterball_mapper_object: Run clusterball mapper

In mappeR: Construct and Visualize TDA Mapper Graphs

Run clusterball mapper

Description

Run ball mapper, but additionally cluster within the balls. Can use two different distance matrices to accomplish this.

Usage

create_clusterball_mapper_object(
  data,
  dist1,
  dist2,
  eps,
  clusterer = hierarchical_clusterer("single")
)

Arguments

data	A data frame.
dist1	A distance matrix for the data frame; this will be used to ball the data.
dist2	Another distance matrix for the data frame; this will be used to cluster the data after balling.
eps	A positive real number for your desired ball radius.
clusterer	A function which accepts a list of distance matrices as input, and returns the results of clustering done on each distance matrix.

Value

A list of two dataframes, one with node data containing bin membership, datapoints per cluster, and cluster dispersion, and one with edge data containing sources, targets, and weights representing overlap strength.

Examples

data = data.frame(x = sapply(1:100, function(x) cos(x)), y = sapply(1:100, function(x) sin(x)))
data.dists = dist(data)
eps = 1

create_clusterball_mapper_object(data, data.dists, data.dists, eps)
