Plotting of graphs
plot.igraph is able to plot graphs to any R device. It is the
non-interactive companion of the
## S3 method for class 'igraph': plot(x, axes = FALSE, add = FALSE, xlim = c(-1, 1), ylim = c(-1, 1), mark.groups = list(), mark.shape = 1/2, mark.col = rainbow(length(mark.groups), alpha = 0.3), mark.border = rainbow(length(mark.groups), alpha = 1), mark.expand = 15, ...)
- The graph to plot.
- Logical, whether to plot axes, defaults to FALSE.
- Logical scalar, whether to add the plot to the current device, or delete the device's current contents first.
- The limits for the horizontal axis, it is unlikely that you want to modify this.
- The limits for the vertical axis, it is unlikely that you want to modify this.
- A list of vertex id vectors. It is interpreted as a set
of vertex groups. Each vertex group is highlighted, by plotting a colored
smoothed polygon around and
underit. See the arguments below to control the look of the polygons.
- A numeric scalar or vector. Controls the smoothness of the
vertex group marking polygons. This is basically the
shapeparameter of the
xsplinefunction, its possible values are betw
- A scalar or vector giving the colors of marking the
polygons, in any format accepted by
xspline; e.g. numeric color ids, symbolic color names, or colors in RGB.
- A scalar or vector giving the colors of the borders of
the vertex group marking polygons. If it is
NA, then no border is drawn.
- A numeric scalar or vector, the size of the border around the marked vertex groups. It is in the same units as the vertex sizes. If a vector is given, then different values are used for the different vertex groups.
- Additional plotting parameters. See igraph.plotting for the complete list.
One convenient way to plot graphs is to plot with
first, handtune the placement of the vertices, query the coordinates by the
tk_coords function and use them with
plot the graph to any R device.
g <- ring(10) plot(g, layout=layout_with_kk, vertex.color="green")
