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,
loop.size = 1,
...
)
```

`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. |

`loop.size` |
A numeric scalar that allows the user to scale the loop edges of the network. The default loop size is 1. Larger values will produce larger loops. |

`...` |
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.

`layout()`

for different layouts,
igraph.plotting for the detailed description of the plotting
parameters and `tkplot()`

and `rglplot()`

for other
graph plotting functions.

Other plot:
`rglplot()`

```
g <- make_ring(10)
plot(g, layout = layout_with_kk, vertex.color = "green")
```
