Plotting of graphs

plot.graph is able to plot graphs to any R device. It is the non-interactive companion of the tkplot function.

Keywords
graphs
Usage
plot.igraph(x, layout = layout.random, layout.par = list(), 
    labels = NULL, label.color = "darkblue", label.font = NULL, 
    label.degree = -pi/4, label.dist = 0, vertex.color = "SkyBlue2", 
    vertex.size = 15, edge.color = "darkgrey", edge.width = 1,
    edge.labels = NA, axes = FALSE, xlab = "", ylab = "", ...)
Arguments
x
The graph to plot.
layout
The coordinates of the vertices, or the method to calculate them. See the same argument of tkplot.
layout.par
List, the parameters of the layout function. See the same argument of tkplot.
labels
The labels of the vertices. See the same argument of tkplot.
label.color
The color(s) of the labels. See the same argument of tkplot.
label.font
The font to be used for the labels. Right now all labels use the same font.
label.degree
Specifies the placement of the labels of the vertices. See the same argument of tkplot.
label.dist
Specifies the placement of the vertex labels. See the same argument of tkplot.
vertex.color
The color(s) of the vertices. See the same argument of tkplot.
vertex.size
The size(s) of the vertices. See the same argument of tkplot.
edge.color
The color(s) of the edges. See the same argument of tkplot.
edge.width
The width(s) of the edges. See the same argument of tkplot.
edge.labels
Labels for the edges, this will be converted to a character vector. The default is NA which suppresses edge labels. The vector might contain NA's as well to suppress labels for some edges.
axes
Logical, whether to plot axes, defaults to FALSE.
xlab
The label of the horizontal axis. Defaults to the empty string.
ylab
The label of the vertical axis. Defaults to the empty string.
...
Additional arguments, passed to plot.
Details

One convenient way to plot graphs is to plot with tkplot first, handtune the placement of the vertices, query the coordinates by the tkplot.getcoords function and use them with plot to plot the graph to any R device. The additional arguments specified are passed to the plot function.

Value

  • Returns NULL, invisibly.

layout for different layouts, tkplot for the better description of the parameters and an interactive version.
