(each of class containing the class dg.Vertex)
created by returnVertexList
or exported from dynamicGraphMain.

created by setBlocks
or exported from dynamicGraphMain.
dg
dg is an object of class
dg.graphedges-class.

NULL, or object with the methods modifyModel
and testEdge - for respectively updating the
object when the graph is updated, and for computing the
test statistic when an edge is labeled. The returned object from
testEdge should have the methods
label and width
for extracting the label of a test for putting the label on the edge
and for extracting the width for the edge.

this name in .Global.Env when the object is updated.

Details
This is a dynamic plotting tool for handling graphs.
The lay out of the graph can be edited by moving
the vertices of the graph by the mouse, and edges can be
added by clicking vertices and dropping by clicking the edges.
The function is incremental in the sense that the user can add a method
for updating the model object of the window when the graph is updated,
and a method for computing the test of an edge when the edge is clicked
by the mouse.
Edges can be oriented, drawn by arrows.
Blocks can be used to define a causal structure of the variables
represented by vertices, and edges between blocks are then oriented.
Blocks can be given in a structure such that descendant blocks of a blocks
also are closed when a block is closed.
A secondary set of vertices, factor vertices, can be used to represent
hypergraphs.
"Slave graph windows" can be created: The windows will share vertices
and blocks, thus when a vertex is moved in one window, the position of
the vertex will also change in all slave windows. The edges are not
shared among windows, since the individual windows will typical
represent different models.
Thus factors (vertices and edges) are not shared between graph windows.
Value

(if not returnNull is TRUE)

and list of models, each (of class DynamicGraphModel-class)

The model object of the call of dynamicGraphMain
should have the methods modifyModel, testEdge,
graphEdges, and setGraphEdges.
When the graph is modified, by adding or dropping vertices or edge,
the method modifyModel is called on the argument object
of dynamicGraphMain. If an object is returned in
the list of the returned value from modifyModel then
object in dynamicGraphMain is replaced by this
object, and the object is also assigned in the top level environment,
if objectName was given to dynamicGraphMain.
The method testEdge of object should return an object with
the methods label and width for labeling edges,
see dg.Test-class.
The methods graphEdges and setGraphEdges
are used to communicate the graph components between several views
of the same model.
The method graphEdges of the model object is for
returning an object of class dg.graphedges-class
to draw in the view, depending on the viewType.
The method setGraphEdges of the model object
is called on the model object when the model is modified.
