CoverRef: Cover abstract class
In peekxc/Mapper: Topological Data Analysis using Mapper

Description Usage Format Fields Author(s)

Reference Class (R6) implementation of a Cover. This class is meant to act as an abstract class to derive other types of covering generators with. Minimally, a derived covering class must implement the 'construct_cover' method to populate the 'level_sets' list with point indices, and any parameters that the derived class requires.

Additional methods may also be added to improve the efficiency of the cover. See the vignette on creating a custom cover for details.

An R6Class generator object

The following is a list of the fields available for derived classes. Each may be accessed by the self environment. See ?R6 for more details.

level_sets: named list, indexed by index_set, whose values represent indices in the original data set to cluster over.
index_set: character vector of keys that uniquely index the open sets of the cover.
typename: unique string identifier identifying the covering method.
