Coercion Methods for Simplicial Complex Data Structures.
interplex
This is an R package to facilitate conversion between different structures for simplicial complex data.
usage
installation
{interplex} is now on CRAN and can be installed as follows:
install.packages("interplex")
supported structures
{interplex} includes converters between the following data structures:
- complete lists of simplices, used by the {TDA} package
- simplex tree instances of class 'Rcpp_SimplexTree', provided by the {simplextree} package
- simplex trees in Python GUDHI imported using the {reticulate} package
- objects of class 'igraph', provided by the {igraph} package
- objects of class 'network', provided by the {network} package
Coercion among the graph/network classes is done using methods from the {intergraph} package. Simplicial complexes are only directly coerced between the 'igraph' class.
development
Install the development version of {interplex} from GitHub as follows:
remotes::install_github("tdaverse/interplex")
future directions
A future release should extend coercers from (unannotated) simplicial complexes to simplicial filtrations (in which simplices are annotated with real-values) and possibly arbitrary simplicial maps (with real-valued intervals).
