Place nodes on a line or circle
This layout puts all nodes on a line, possibly sorted by a node attribute. If
circular = TRUE the nodes will be laid out on the unit circle instead.
In the case where the sort.by attribute is numeric, the numeric values
will be used as the x-position and it is thus possible to have uneven spacing
between the nodes.

An |
circular |
Logical. Should the layout be transformed to a circular
representation. Defaults to |
sort.by |
The name of a node variable to sort the nodes by. |
use.numeric |
Logical. Should a numeric sort.by attribute be used as the actual x-coordinates in the layout. May lead to overlapping nodes. Defaults to FALSE |

If |
A data.frame with the columns x, y, circular as
well as any information stored as node variables in the tbl_graph object.
