Description Objects from the Class Slots Extends Methods Note Author(s) See Also Examples

A skeleton class for the classes of vertices.

Objects has the methods for extracting and setting the slots for vertices.

`name`

:Object of class

`"character"`

with the`name`

of the vertex. Should be a valid name on variables for your model object.`index`

:Object of class

`"numeric"`

with the`index`

of the vertex, the position of the vertex in a vertex list.`position`

:Object of class

`"numeric"`

with the`position`

of the vertex. Vertices in the same dynamic graph should have the same number of coordinates.`blockindex`

:Object of class

`"numeric"`

with the`blockindex`

of the vertex.`stratum`

:Object of class

`"numeric"`

with the`stratum`

of the vertex.`constrained`

:Object of class

`"logical"`

: If TRUE, then the vertex can not be dragged out of the block of the vertex.`color`

:Object of class

`"character"`

with the`color`

of the vertex.`label`

:Object of class

`"character"`

with the`label`

of the vertex.`label.position`

:Object of class

`"numeric"`

with the`label.position`

of the vertex. Labels of vertices in the same dynamic graph should have the same number of coordinates.

Class `"dg.Node"`

, directly.

The `dg.Vertex`

class has the methods
`name`

, `label`

, `labelPosition`

,
`position`

, `stratum`

,
`blockindex`

,
`constrained`

,
`color`

, and `index`

for extracting values of the object and the replacement methods
`name<-`

, `label<-`

, `labelPosition<-`

,
`position<-`

, `stratum<-`

,
`blockindex<-`

,
`constrained<-`

,
`color<-`

, and `index<-`

.
The method `draw`

is used to draw a vertex,
and items can be added to the pop up menu of the vertex
by the method `addToPopups`

.

Some of these methods also applies for
edges (`dg.Edge`

),
blocks (`dg.Block`

),
block edges
(`dg.BlockEdge`

),
factor vertices (`dg.FactorVertex`

)
and edges from vertices to factors (`dg.FactorEdge`

).
