Ragraph-class {Rgraphviz} | R Documentation |
Class Ragraph
is used to handle libgraph
representations of R graph objects.
Objects can be created by calls to the function agopen
.
agraph
:"externalptr"
: A C
based structure containing the libgraph informationlaidout
:"logical"
: Whether or
not this graph has been laid out or not.layoutType
:"character"
: The
layout method used for this objectedgemode
:"character"
: The
edgemode for this graph - “directed” or “undirected”AgNode
:"list"
: A list of
AgNode
objects.AgEdge
:"list"
: A list of
AgEdge
objects.boundBox
:"boundBox"
: Defines
the bounding box of the plot.signature(object = "Ragraph")
: A brief summary of
the contentssignature(object = "Ragraph")
: Returns the
external libgraph pointersignature(object = "Ragraph")
: Returns the
laidout
slotsignature(object = "Ragraph")
: Returns the
bounding box.signature(object = "Ragraph")
: Returns the edge
list.signature(object = "Ragraph")
: Returns the node
list.signature(object = "Ragraph")
: Retrieves the
edgemode of this object.signature(object = "Ragraph")
: Retrieves the
method used for the layout of this graph.signature(object = "Ragraph")
: Returns a
vector of the names of the edges in this graph.signature(object = "Ragraph")
: Returns a two
element list, the first element contains a numerical vector with
the 'x' positions of every node in this graph, and the second
element contains a numerical vector with the 'y' positions for
every node in the graph.signature(object = "Ragraph")
: Returns a
vector with the heights of every node in the graphsignature(object = "Ragraph")
: Returns a
vector with the left width of every node in the graph.signature(object = "Ragraph")
: Returns a
vector with the right width of every node in the graph.Jeff Gentry
