ng_graph: Create an NG_data object to be used by a navGraph session

Description

NG_graph objects wrap the transition graphs and additional information such as graph name and graph layout.

The node names of the graph split by the chosen sep character sting must match either the variable names- or the short names of the NG_data object.

Usage

ng_graph(name, graph, sep = ":", layout = "circle")

Arguments

name

Name of graph. This name will be displayed in the pull down menu within a navGraph session.

graph

Undirected graph objects of class graph. See the package graph.

sep

Node names represent a set of variables whose name are separated by the character string sep (containing no spaces).

layout

One of the following strings: "circle", "kamadaKawaiSpring", "fruchtermanReingold" or "random".

• NG_graph object.

LG <- linegraph(G, sep = "++")

ng.lg <- ng_graph("3d transition", LG, "++", "fruchtermanReingold" )
plot(ng.lg)
