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.
layout_igraph_linear(graph, circular, sort.by = NULL, use.numeric = FALSE,
offset = pi/2)
An igraph object
Logical. Should the layout be transformed to a circular
representation. Defaults to FALSE
.
The name of a vertex attribute to sort the nodes by.
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 circular = TRUE
, where should it begin. Defaults to
pi/2
which is equivalent to 12 o'clock.
A data.frame with the columns x
, y
, circular
as
well as any information stored as vertex attributes on the igraph object.
