R: Adding and removing nodes/edges from 'gexf' objects

add.gexf.node {rgexf}

R Documentation

Adding and removing nodes/edges from `gexf` objects

Description

Manipulates gexf objects adding and removing nodes and edges from both, its dataframe representation and its XML representation.

Usage

add.gexf.node(graph, id=NA, label=NA, start=NULL, end=NULL,
   vizAtt=list(color=NULL, position=NULL, size=NULL, shape=NULL, image=NULL),
   atts=NULL)

add.gexf.edge(graph, source, target, id=NULL, type=NULL, label=NULL, start=NULL,
   end=NULL, weight=1, vizAtt = list(color=NULL, thickness=NULL, shape=NULL),
   atts=NULL, digits = getOption("digits"))

rm.gexf.node(graph, id=NULL, number=NULL, rm.edges = TRUE)

rm.gexf.edge(graph, id=NULL, number=NULL)

add.node.spell(graph, id=NULL, number=NULL, start=NULL, end=NULL,
   digits = getOption("digits"))

add.edge.spell(graph, id=NULL, number=NULL, start=NULL, end=NULL,
   digits = getOption("digits"))

Arguments

`graph`	A gexf-class object.
`id`	A node/edge id (normaly numeric value).
`label`	A node/edge label.
`type`	Type of conection (edge).
`number`	Index number(s) of a single or a group of nodes or edges.
`weight`	Edge weight.
`vizAtt`	A list of node/edge viz attributes (see `write.gexf`).
`atts`	List of attributes, currently ignored.
`source`	Source node's id.
`target`	Target node's id.
`start`	Starting time period
`end`	Ending time period
`rm.edges`	Whether to remove or not existing edges.
`digits`	Integer. Number of decimals to keep for nodes/edges sizes. See `print.default`

Details

new.gexf.graph Creates a new gexf empty object (0 nodes 0 edges).

add.gexf.node and add.gexf.edge allow adding nodes and edges to a gexf object (graph) one at a time. rm.gexf.node and rm.gexf.edges remove nodes and edges respectively.

In the case of rm.gexf.node, by default every edge linked to the node that is been removed will also be removed (rm.edges = TRUE).

add.node.spell and add.edge.spell allow to include spells to specific nodes or edges in a gexf object.

Value

A gexf object (see write.gexf).
