ng_graph: Create an NG_data object to be used by a navGraph session
In RnavGraph: Using Graphs as a Navigational Infrastructure

Description Usage Arguments Details Value Author(s) See Also Examples

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.

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

`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".

The number of sep occurrences in each node name of the graph must be the same.

NG_graph object.
