plot.igraph | R Documentation |
plot.igraph
is able to plot graphs to any R device. It is the
non-interactive companion of the tkplot
function.
## 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, ... )
x |
The graph to plot. |
axes |
Logical, whether to plot axes, defaults to FALSE. |
add |
Logical scalar, whether to add the plot to the current device, or delete the device's current contents first. |
xlim |
The limits for the horizontal axis, it is unlikely that you want to modify this. |
ylim |
The limits for the vertical axis, it is unlikely that you want to modify this. |
mark.groups |
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 “under” it. See the arguments below to control the look of the polygons. |
mark.shape |
A numeric scalar or vector. Controls the smoothness of the
vertex group marking polygons. This is basically the ‘shape’
parameter of the |
mark.col |
A scalar or vector giving the colors of marking the
polygons, in any format accepted by |
mark.border |
A scalar or vector giving the colors of the borders of
the vertex group marking polygons. If it is |
mark.expand |
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 tkplot
first, handtune the placement of the vertices, query the coordinates by the
tk_coords
function and use them with plot
to
plot the graph to any R device.
Returns NULL
, invisibly.
