check_graph: Check input graph

In graphicalExtremes: Statistical Methodology for Graphical Extreme Value Models

Check input graph

Description

Checks that the input graph is a valid graph for an extremal graphical model. If necessary, converts the graph to an undirected graph. Removes vertex labels if present.

Usage

check_graph(
  graph,
  graph_type = c("general", "decomposable", "block", "tree"),
  check_connected = TRUE,
  nVertices = NULL
)

Arguments

graph	An [igraph::graph] object.
graph_type	"general", "decomposable", "block", "tree". The required type of graph.
check_connected	Whether to check if the graph is connected.
nVertices	The number of vertices required in the graph.

Value

The given graph, if necessary converted to undirected. If the graph is not valid an error is thrown.
