`plot.igraph`

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

function.

```
# S3 method for 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 `xspline`

function, its possible
values are between -1 and 1. If it is a vector, then a different value is
used for the different vertex groups.

mark.col

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.

mark.border

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.

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.

Returns `NULL`

, invisibly.

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.

`layout`

for different layouts,
`igraph.plotting`

for the detailed description of the plotting
parameters and `tkplot`

and `rglplot`

for other
graph plotting functions.
