Usage

graphviz.plot(x, highlight = NULL, layout = "dot", shape = "circle",
    main = NULL, sub = NULL)

Arguments

x

an object of class bn.

highlight

a list, see below.

layout

a character string, the layout parameter to be passed to Rgraphviz. Possible values are dots, neato, twopi, circo and fdp. See Rgraphviz documentation for d

shape

a character string, the shape of the nodes. Can be either circle or ellipse.

Details

The highlight parameter is a list with at least one of the following elements:

• arcs: the arcs to be highlighted (a two-column matrix, whose columns are labeledfromandto).

and optionally one or more of the following formatting parameters:

• col: an integer or character string (the highlight colour). The default value isred.
• fill: an integer or character string (the colour used as a background colour for the nodes). The default value iswhite.
• lwd: a positive number (the line width of highlighted arcs). It overrides the line width settings instrength.plot. The default value is to use the global settings ofRgraphviz.
