contract_brainGraph: Contract graph vertices based on brain lobe and hemisphere
In brainGraph: Graph Theory Analysis of Brain MRI Data

Description Usage Arguments Details Value Author(s) See Also

Create a new graph after merging vertices within specified groups. By default, groups are brain lobe and hemisphere membership.

1	contract_brainGraph(g, vgroup = "lobe.hemi")

`g`	A `brainGraph` graph object
`vgroup`	Character string; the name of the vertex attribute to use when contracting the graph. Default: `'lobe.hemi'`

The size vertex-level attribute of the resultant graph is equal to the number of vertices in each group. The x-, y-, and z-coordinates of the new graph are equal to the mean coordinates of the vertices per group. The new edge weights are equal to the number of inter-group connections of the original graph.

A new brainGraph graph object with vertex-level attributes representing the mean spatial coordinates, and vertex- and edge-level attributes of color names
