dgraphs

dgraphs constructs and analyzes graphs derived from numerical observations. It includes mutual and shared-neighbor graphs, intersection and geodesic nearest-neighbor graphs, radius and adaptive-radius graphs, and minimum-spanning-tree completion. Utilities for conversion, pruning, diagnostics, spectral embedding, endpoints, and paths are also provided.

Installation

Once the package is available from CRAN, install it with:

install.packages("dgraphs")

Example

library(dgraphs)

set.seed(1)
x <- matrix(rnorm(80), ncol = 2)
graph <- create.mknn.graph(x, k = 4)

length(graph$adjacency.list)
