Overview

About

Maintained by Pawel GajerCRAN page ↗GitHub ↗Issues ↗

Constructs data-derived graphs from numerical observations using mutual, shared-neighbor, intersection, geodesic, radius, adaptive-radius, and minimum-spanning-tree completion methods. Provides graph conversion, pruning, diagnostics, spectral embedding, endpoint detection, and path utilities. The implemented graph constructions include methods described by Jarvis and Patrick (1973) doi:10.1109/T-C.1973.223640, Brito et al. (1997) doi:10.1016/S0167-7152(96)00213-1, Berry and Sauer (2019) doi:10.3934/fods.2019001, and Gower and Ross (1969) doi:10.2307/2346439.

Changes in 0.2.0

Breaking API changes

Removes the deprecated create.radius.graph() and create.adaptive.radius.graph() compatibility wrappers. Use create.rknn.graph() with type = "fixed" or type = "adaptive.radius", respectively.
Removes the temporary public backend entry point cpp.create.rknn.graphs(). Use create.rknn.graphs(backend = "cpp").
Internalizes the low-level dist.to.knn(), euclidean.distance(), and graph.adj.mat() helpers.
Removes the superseded adjlist.to.igraph() conversion function. as_igraph() now accepts bare adjacency lists and an optional aligned weight.list argument.

Removes the unused graph-edit workflow comprising graph.edit.distance(), load.graph.data(), calculate.edit.distances(), and create.distance.plot().

Other changes

Fixes a C++ One Definition Rule violation reported by CRAN's special link-time-optimization check. The minimum-spanning-tree implementation now uses a privately scoped edge type, and an unused conflicting intersection-kNN helper type has been removed. This does not change the R API or graph semantics.
Fixes an ANN fixed-radius boundary issue that could omit adaptive-radius edges lying exactly at a local-scale threshold. In particular, the adaptive maximum-radius rule with factor one now reproduces symmetric-kNN edges for exact, tie-free searches.
Clarifies that the historical rel_geodesic_stress diagnostic is a target-normalized graph-geodesic relative RMSE, not Kruskal's Stress-1.
Adds a full workflow vignette covering graph construction, lifecycle diagnostics, connectivity repair, parameter sequences, conversion to igraph, and geodesic-isometry diagnostics.
Expands examples across the exported API in preparation for an R Journal package paper.
Extends as_igraph() to current dgraphs graph objects while preserving support for legacy basin graph objects.

From NEWS.md in the release

Install

R (CRAN)pak (dev)Ubuntu (r2u)Fedora (COPR)openSUSE (OBS)

install.packages("dgraphs", repos = "https://cloud.r-project.org/")

Installs the current CRAN release. Prebuilt binaries on Windows and macOS.

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

Development version from pgajer/dgraphs. Installs pak first if it is not already available.

Release

# enable cranapt (r2u) if it is not already set up, then install
grep -rqs r2u.stat.illinois.edu /etc/apt/sources.list /etc/apt/sources.list.d/ \
  || curl -fsSL https://raw.githubusercontent.com/eddelbuettel/r2u/master/inst/scripts/add_cranapt_noble.sh | sudo bash
sudo apt install -y r-cran-dgraphs

Fast Ubuntu binaries via r2u (no compilation). The cranapt setup runs once and is skipped when it is already enabled. We list this channel from recorded r2u download activity rather than from a live index of the repository, so treat it as last known rather than guaranteed.

bspm (used by r2u) also needs make: sudo apt install make

# enable the iucar/cran COPR if it is not already present, then install
ls /etc/yum.repos.d/*iucar*cran*.repo >/dev/null 2>&1 \
  || sudo dnf copr enable -y iucar/cran
sudo dnf install -y R-CRAN-dgraphs

RPMs from the iucar/cran COPR, rebuilt from CRAN.

For install.packages() integration in R, also: sudo dnf install R-CoprManager

# add the autoCRAN OBS repo (Tumbleweed) if it is missing, then install
zypper -q lr | grep -qi autoCRAN \
  || sudo zypper addrepo https://download.opensuse.org/repositories/devel:/languages:/R:/autoCRAN/openSUSE_Tumbleweed/devel:languages:R:autoCRAN.repo
sudo zypper install -y R-dgraphs

RPMs auto-built from CRAN on openSUSE OBS (Tumbleweed). We list this channel from recorded autoCRAN download activity rather than from a live index of the repository, so treat it as last known rather than guaranteed.
