Define a filter (lens) function on the data. 2. Perform clustering within each level set. 3. Generate a complex from the clustering results.https://github.com/r-universe/tda-r/actions/runs/25790484115Mon, 13 Apr 2026 14:21:22 GMTMapperAlgo1.1.0successhttps://tda-r.r-universe.devhttps://github.com/tda-r/mapperalgokennywang2003@gmail.com (ChiChien Wang)Provides an implementation of simplicial complexes for Topological Data Analysis (TDA). The package includes functions to compute faces, boundary operators, Betti numbers, Euler characteristic, and to construct simplicial complexes. It also implements persistent homology, from building filtrations to computing persistence diagrams, with the aim of helping readers understand the core concepts of computational topology. Methods are based on standard references in persistent homology such as Zomorodian and Carlsson (2005) <doi:10.1007/s00454-004-1146-y> and Chazal and Michel (2021) <doi:10.3389/frai.2021.667963>.https://github.com/r-universe/tda-r/actions/runs/25786367871Sun, 14 Dec 2025 07:47:55 GMTSimplicialComplex0.1.0successhttps://tda-r.r-universe.devhttps://github.com/tda-r/simplicialcomplex
