# 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:
1. Nodes/edges attributes,
2. GEXF viz attributes (such as color, size, and position),
3. Network dynamics (for both edges and nodes, including spells) and
4. 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](https://github.com/raphv/gexf-js) library and interact with
the igraph package.
# Changes in rgexf version 0.16.3 (2024-06-27)
- Dynamically loaded components in the Rd files were removed to comply
with new CRAN policies.
More in the [NEWS.md](NEWS.md) file.
# Installation
To install the latest version of `rgexf`, you can use `devtools`
``` r
library(devtools)
install_github("gvegayon/rgexf")
```
The more stable (but old) version of `rgexf` can be found on CRAN too:
install.packages("rgexf")
# Citation
``` r
citation(package="rgexf")
```
To cite rgexf in publications use the following paper:
Vega Yon G (2021). "Building, Importing, and Exporting GEXF Graph
Files with rgexf." _Journal of Open Source Software_, *6*, 3456.
doi:10.21105/joss.03456 ,
.
And the actual R package:
Vega Yon G, Fábrega Lacoa J, Kunst J (????). _netdiffuseR: Build,
Import and Export GEXF Graph Files_. doi:10.5281/zenodo.5182708
, R package version 0.16.3,
.
To see these entries in BibTeX format, use 'print(,
bibtex=TRUE)', 'toBibtex(.)', or set
'options(citation.bibtex.max=999)'.
# Examples
## Example 1: Importing GEXF files
We can use the `read.gexf` function to read GEXF files into R:
``` r
# Loading the package
library(rgexf)
g <- system.file("gexf-graphs/lesmiserables.gexf", package="rgexf")
g <- read.gexf(g)
head(g) # Taking a look at the first handful
```
Gephi 0.9
...
...
Moreover, we can use the `gexf.to.igraph()` function to convert the
`gexf` object into an `igraph` object:
``` r
library(igraph)
```
Attaching package: 'igraph'
The following objects are masked from 'package:stats':
decompose, spectrum
The following object is masked from 'package:base':
union
``` r
ig <- gexf.to.igraph(g)
op <- par(mai = rep(0, 4)) # Making room
plot(ig)
```
``` r
par(op)
```
Using the `plot.gexf` method–which uses the `gexf-js` JavaScript
library–results in a Web visualization of the graph, like this:
``` r
plot(g)
```
A live version of the figure is available
[here](https://gvegayon.github.io/rgexf/lesmiserables/).
## Example 2: Static net
``` r
# Creating a group of individuals and their relations
people <- data.frame(matrix(c(1:4, 'juan', 'pedro', 'matthew', 'carlos'),ncol=2))
people
```
X1 X2
1 1 juan
2 2 pedro
3 3 matthew
4 4 carlos
``` r
# Defining the relations structure
relations <- data.frame(matrix(c(1,4,1,2,1,3,2,3,3,4,4,2), ncol=2, byrow=T))
relations
```
X1 X2
1 1 4
2 1 2
3 1 3
4 2 3
5 3 4
6 4 2
``` r
# Getting things done
write.gexf(people, relations)
```

## Example 3: Dynamic net
``` r
# Defining the dynamic structure, note that there are some nodes that have NA at the end.
time<-matrix(c(10.0,13.0,2.0,2.0,12.0,rep(NA,3)), nrow=4, ncol=2)
time
```
[,1] [,2]
[1,] 10 12
[2,] 13 NA
[3,] 2 NA
[4,] 2 NA
``` r
# Getting things done
write.gexf(people, relations, nodeDynamic=time)
```
NodosChile
A GEXF file written in R with "rgexf"
GEXF, NodosChile, R, rgexf, Gephi
## Example 4: More complex… Dynamic graph with attributes both for nodes and edges
First, we define dynamics
``` r
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
``` r
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
``` r
# 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
``` r
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
``` r
# Getting the things done
write.gexf(nodes=people, edges=relations, edgeDynamic=time.edges,
edgesAtt=edge.att, nodeDynamic=time.nodes, nodesAtt=node.att)
```
