rgexf (version 0.15.3)

rgexf Methods: S3 methods for gexf objects

Description

Methods to print and summarize gexf class objects

Usage

"print"(x, file=NA, replace=F, ...) "summary"(object, ...) "plot"(x, EdgeType = c("curve", "line"), output.dir = NULL, ...)

Arguments

x

An gexf class object.

object

An gexf class object.

file

String. Output path where to save the GEXF file.

replace

Logical. If file exists, TRUE would replace the file.

EdgeType

For the visualization

output.dir

String. The complete path where to export the sigmajs visualization

...

Ignored

Value

print.gexf

None (invisible NULL).

summary.gexf

List containing some gexf object statistics.

plot.gexf

None (invisible NULL).

Details

print.gexf displays the graph (XML) in the console. If file is not NA, a GEXF file will be exported to the indicated filepath. summay.gexf prints summary statistics and information about the graph. plot.gexf plots the graph object in the web browser using sigma-js javascript library. Generated files are stored at the OS's “temp” folder. If output.dir is not NULL, then all files required to display the graph in the web browser will be saved in the output.dir. Users must note that plot.gexf starts a server using the Rook package, otherwise it will not be possible to see the visualization (sigmajs requires this). to
