| 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(self= "Ragraph"):
Gets default attributes of the given graph.signature(self= "Ragraph", attr="vector", value="vector"):
Sets default attributes of the given graph.signature(self= "Ragraph", attr="vector"):
Gets attributes of the given graph.signature(self= "Ragraph", attr="vector", value="vector"):
Sets attributes of the given graph.signature(self= "Ragraph", cluster="numeric", attr="vector"):
Gets attributes of a cluster for the given graph.signature(self= "Ragraph", cluster="numeric", attr="vector", value="vector"):
Sets attributes of a cluster for the given graph.signature(self= "Ragraph",attr="missing"):
Gets default attributes of the given edge.signature(self= "Ragraph", attr="vector", value="vector"):
Sets default attributes of the given edge.signature(self= "Ragraph", from="vector", to="vector", attr="vector"):
Gets attributes of the given edge.signature(self= "Ragraph", from="vector", to="vector", attr="vector", value="vector"):
Sets attributes of the given edge.signature(self= "Ragraph",attr="missing"):
Gets default attributes of the given node.signature(self= "Ragraph", attr="vector", value="vector"):
Sets default attributes of the given node.signature(self= "Ragraph", n="vector", attr="vector"):
Gets attributes of the given node.signature(self= "Ragraph", n="vector", attr="vector", value="vector"):
Sets attributes of the given node.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 and Li Long <li.long@isb-sib.ch>
