| dg.Edge-class {dynamicGraph} | R Documentation |
A skeleton class for the classes of edges.
Objects has the methods for extracting and setting the slots for edges, and the method for drawing the edge.
vertex.indices:"numeric":
The vertex.indices of the vertices of the edge. width:"numeric":
The width of the edge. dash:"character":
The dash pattern of the edge.
From the Tcl/tk Reference Manual:
"DASH PATTERNS
Many items support the notion of an dash pattern for outlines.
The first possible syntax is a list of integers. Each element represents the number of pixels of a line segment. Only the odd segments are drawn using the "outline" color. The other segments are drawn transparant.
The second possible syntax is a character list containing only 5 possible characters $[.,-_ ]$. The space can be used to enlarge the space between other line elements, and can not occur as the first position in the string. Some examples: -dash . = -dash {2 4} -dash - = -dash {6 4} -dash -. = -dash {6 4 2 4} -dash -.. = -dash {6 4 2 4 2 4} -dash {. } = -dash {2 8} -dash , = -dash {4 4}
The main difference of this syntax with the previous is that it it shape-conserving. This means that all values in the dash list will be multiplied by the line width before display. This assures that "." will always be displayed as a dot and "-" always as a dash regardless of the line width.
On systems which support only a limited set of dash patterns, the dash pattern will be displayed as the closest dash pattern that is available. For example, on Windows only the first 4 of the above examples are available. The last 2 examples will be displayed identically to the first one. "
