Usage
rglplot (x, layout = layout.random, layout.par = list(), labels = NULL,
label.color = "darkblue", label.font = NULL, label.degree = -pi/4,
label.dist = 0, vertex.color = "SkyBlue2", vertex.size = 15,
edge.color = "darkgrey", edge.width = 1, edge.labels = NA,
...)
Arguments
layout
A function or matrix giving the coordinates of the
vertices. See the same argument of tkplot
. layout.par
A named list specifying the optional parameters of the layout
function, only used if the layout
argument is a
function. The parameters themselves are layout function dependent,
they are discussed in the
labels
Gives the labels to use for the vertices. It can be a
numeric or character vector. If NA
the plot will have no
labels, if NULL
numeric ids starting from one will be
used. If a character vector of length one with prefi
label.color
The color of the labels. If it is a character
scalar with prefix a:
then the corresponding vertex
attribute will be used. Otherwise if it is a vector of length one
then all labels will be the same color. It can al
label.font
The font for the labels, currently not used.
label.degree
Governs the placement of the vertex labels. 0
is right, pi/2 is down, pi is left. This argument can be a constant
(for all labels) or a numeric vector. If it is a constant string
with prefix a:
then the correspond
label.dist
Numeric constant, gives the distance between the
labels and the vertices. 1 is some ideal distance,
based on the vertex and label sizes. Use 0 for drawing the labels on
the vertices.
vertex.color
The color of the vertices, either a character
constant with prefix a:
for using an attribute or
without it: a constant color for all vertices, or a numeric or
character or numeric vector giving the different color
vertex.size
The size of the vertices. Either a numeric
constant, or a numeric vector, or a string with prefix
a:
giving the vertex attribute to use.
edge.color
The color of the edges. Either a character vector
with prefix a:
naming the edge attribute to use or
one without it, or a numeric or character vector giving the colors
for each edge.
edge.width
The width of the edges. Either a numeric constant or
a numeric vector, or a string with prefix a:
giving
the edge attribute to use.
edge.labels
Labels for the edges, this will be converted to a
character vector. The default is NA
which suppresses edge
labels. The vector might contain NA
's as well to suppress
labels for some edges.
