Overview

About

Maintained by Jason Cory BrunsonCRAN page ↗GitHub ↗

Computational topology, which enables topological data analysis (TDA), makes pervasive use of abstract mathematical objects called simplicial complexes; see Edelsbrunner and Harer (2010) doi:10.1090/mbk/069. Several R packages and other software libraries used through an R interface construct and use data structures that represent simplicial complexes, including mathematical graphs viewed as 1-dimensional complexes. This package provides coercers (converters) between these data structures. Currently supported structures are complete lists of simplices as used by 'TDA'; the simplex trees of Boissonnat and Maria (2014) doi:10.1007/s00453-014-9887-3 as implemented in 'simplextree' and in Python GUDHI (by way of 'reticulate'); and the graph classes of 'igraph' and 'network', by way of the 'intergraph' package.

Changes in 0.1.2

Per updated CRAN requirements, this patch moves several packages that are used in converters from Suggests: to Imports:.

It relieves the previously imposed conditions on tests (though not on examples) that use them. The exceptions are {TDA} and {igraphdata}, which are not used by any converters.

The patch also removes the @docType {roxygen2} tag in favor of "_PACKAGE" and fixes a broken code link and several URLs.

Finally, it uses utils::getFromNamespace() to invoke commands from {simplextree} v0.9.1 that were discontinued it v1.0.0.

Install

R (source archive)pak (dev)

url <- "https://cran.r-project.org/src/contrib/Archive/interplex/interplex_0.1.2.tar.gz"
pkgFile <- "interplex_0.1.2.tar.gz"

install.packages(pkgFile, type = "source", repos = NULL)

This package is no longer on CRAN, so install.packages() cannot fetch it by name. This downloads the last archived source (0.1.2) and builds it locally. Install its dependencies first, and note that building from source needs the usual compiler toolchain.

if (!requireNamespace("pak", quietly = TRUE))
  install.packages("pak", repos = "https://cloud.r-project.org/")
pak::pak("tdaverse/interplex")

Development version from tdaverse/interplex. Installs pak first if it is not already available.
