In rgexf: Build, Import, and Export GEXF Graph Files
rgexf: Build, Import and Export GEXF Graph Files 
The first R package to work with GEXF graph files (used in Gephi and
others). rgexf allows reading and writing graph files, including:
-
Nodes/edges attributes,
-
GEXF viz attributes (such as color, size, and position),
-
Network dynamics (for both edges and nodes, including spells) and
-
Edges weighting.
Users can build/handle graphs element-by-element or through data-frames,
visualize the graph on a web browser through ~~sigmajs javascript~~
gexf-js library and interact with
the igraph package.
Changes in rgexf version 0.16.4
New features and changes
-
plot.gexf() now renders graphs as an interactive htmlwidget powered
by sigma.js v3 and
graphology. Node positions, colours,
and sizes are read from the viz:* attributes in the GEXF document.
-
New sigmajs() function creates a sigma.js htmlwidget from a gexf
object or a path to a .gexf file. Shiny helpers sigmajsOutput()
and renderSigmajs() are also available.
-
The legacy gexf-js file-server renderer is preserved as
plot_gexfjs(). The gexfjs() htmlwidget (inline iframe approach) is
likewise kept for backward compatibility.
-
gexfjs() now accepts a gexf object in addition to a file path,
matching sigmajs().
-
gexfjs() has an explicit sizing policy: the widget now defaults to
the full available width and a height of 600px (50% taller than
before) in knitr documents, the browser, and Shiny alike. Both
gexfjs() and sigmajs() honor user-supplied width/height, and
their documented defaults were clarified.
Bug fixes
-
The gexfjs() widget rendered an empty main canvas: the bundled
config.js (which sets zoomLevel, showEdges, and other gexf-js
defaults) was never loaded into the iframe, making every screen
coordinate NaN.
-
Icons and images in the gexfjs() widget (zoom, lens, edge buttons,
search icon, Gephi logo) did not display: relative url(...)
references in the CSS cannot resolve inside a srcdoc iframe, so
images are now inlined as base64 data URIs.
-
The gexfjs() widget’s node-attribute panel was blank and search did
not work: the generated DOM was missing the #leftcontent element,
the search form id had a typo (reacherche), and the autocomplete
list was clipped by the title bar.

Moreover, we can use the gexf.to.igraph() function to convert the
gexf object into an igraph object:
library(igraph)
Attaching package: 'igraph'
The following objects are masked from 'package:stats':
decompose, spectrum
The following object is masked from 'package:base':
union
ig <- gexf.to.igraph(g)
op <- par(mai = rep(0, 4)) # Making room
plot(ig)
par(op)
Using the plot.gexf method–which uses the gexf-js JavaScript
library–results in a Web visualization of the graph, like this:
plot(g)

Example 4: More complex… Dynamic graph with attributes both for nodes and edges
First, we define dynamics
time.nodes<-matrix(c(10.0,13.0,2.0,2.0,12.0,rep(NA,3)), nrow=4, ncol=2)
time.nodes
[,1] [,2]
[1,] 10 12
[2,] 13 NA
[3,] 2 NA
[4,] 2 NA
time.edges<-matrix(c(10.0,13.0,2.0,2.0,12.0,1,5,rep(NA,5)), nrow=6, ncol=2)
time.edges
[,1] [,2]
[1,] 10 5
[2,] 13 NA
[3,] 2 NA
[4,] 2 NA
[5,] 12 NA
[6,] 1 NA
Now we define the attribute values
# Defining a data frame of attributes for nodes and edges
node.att <- data.frame(letrafavorita=letters[1:4], numbers=1:4, stringsAsFactors=F)
node.att
letrafavorita numbers
1 a 1
2 b 2
3 c 3
4 d 4
edge.att <- data.frame(letrafavorita=letters[1:6], numbers=1:6, stringsAsFactors=F)
edge.att
letrafavorita numbers
1 a 1
2 b 2
3 c 3
4 d 4
5 e 5
6 f 6

Moreover, we can use the gexf.to.igraph() function to convert the
gexf object into an igraph object:
library(igraph)
Attaching package: 'igraph'
The following objects are masked from 'package:stats':
decompose, spectrum
The following object is masked from 'package:base':
union
ig <- gexf.to.igraph(g)
op <- par(mai = rep(0, 4)) # Making room
plot(ig)
par(op)
Using the plot.gexf method–which uses the gexf-js JavaScript
library–results in a Web visualization of the graph, like this:
plot(g)

Example 4: More complex… Dynamic graph with attributes both for nodes and edges
First, we define dynamics
time.nodes<-matrix(c(10.0,13.0,2.0,2.0,12.0,rep(NA,3)), nrow=4, ncol=2)
time.nodes
[,1] [,2]
[1,] 10 12
[2,] 13 NA
[3,] 2 NA
[4,] 2 NA
time.edges<-matrix(c(10.0,13.0,2.0,2.0,12.0,1,5,rep(NA,5)), nrow=6, ncol=2)
time.edges
[,1] [,2]
[1,] 10 5
[2,] 13 NA
[3,] 2 NA
[4,] 2 NA
[5,] 12 NA
[6,] 1 NA
Now we define the attribute values
# Defining a data frame of attributes for nodes and edges
node.att <- data.frame(letrafavorita=letters[1:4], numbers=1:4, stringsAsFactors=F)
node.att
letrafavorita numbers
1 a 1
2 b 2
3 c 3
4 d 4
edge.att <- data.frame(letrafavorita=letters[1:6], numbers=1:6, stringsAsFactors=F)
edge.att
letrafavorita numbers
1 a 1
2 b 2
3 c 3
4 d 4
5 e 5
6 f 6
# Getting the things done
write.gexf(nodes=people, edges=relations, edgeDynamic=time.edges,
edgesAtt=edge.att, nodeDynamic=time.nodes, nodesAtt=node.att)
