Visualizing GEXF graph files using gexf-js (legacy)

Source: R/plot.R
plot_gexfjs.Rd

Uses the gexf-js JavaScript viewer by copying static files to a directory and optionally launching a local web server via the servr package. For the modern htmlwidget-based renderer, use plot.gexf or sigmajs.

Usage

gexf_js_config(
  dir,
  graphFile = "network.gexf",
  showEdges = TRUE,
  useLens = FALSE,
  zoomLevel = 0,
  curvedEdges = TRUE,
  edgeWidthFactor = 1,
  minEdgeWidth = 1,
  maxEdgeWidth = 50,
  textDisplayThreshold = 9,
  nodeSizeFactor = 1,
  replaceUrls = TRUE,
  showEdgeWeight = TRUE,
  showEdgeLabel = TRUE,
  sortNodeAttributes = TRUE,
  showId = TRUE,
  showEdgeArrow = TRUE,
  language = FALSE
)

plot_gexfjs(
  x,
  graphFile = "network.gexf",
  dir = tempdir(),
  overwrite = TRUE,
  httd.args = list(),
  copy.only = FALSE,
  ...
)

Arguments

dir

Directory where files are copied (tempdir() by default).

graphFile

Name of the GEXF file written to dir.

showEdges

Logical scalar. Default state of the "show edges" button (nullable).

useLens

Logical scalar. Default state of the "use lens" button (nullable).

zoomLevel

Numeric scalar. Default zoom level. At zoom = 0, the graph should fill a 800x700px zone

curvedEdges

Logical scalar. False for curved edges, true for straight edges this setting can't be changed from the User Interface.

edgeWidthFactor

Numeric scalar. Change this parameter for wider or narrower edges this setting can't be changed from the User Interface.

minEdgeWidth

Numeric scalar.

maxEdgeWidth

Numeric scalar.

textDisplayThreshold

Numeric scalar.

nodeSizeFactor

Numeric scalar. Change this parameter for smaller or larger nodes this setting can't be changed from the User Interface.

replaceUrls

Logical scalar. Enable the replacement of Urls by Hyperlinks this setting can't be changed from the User Interface.

showEdgeWeight

Logical scalar. Show the weight of edges in the list this setting can't be changed from the User Interface.

showEdgeLabel

Logical scalar.

sortNodeAttributes

Logical scalar. Alphabetically sort node attributes.

showId

Logical scalar. Show the id of the node in the list this setting can't be changed from the User Interface.

showEdgeArrow

Logical scalar. Show the edge arrows when the edge is directed this setting can't be changed from the User Interface.

language

Either FALSE, or a character scalar with any of the supported languages.

x

An object of class gexf.

overwrite

Logical scalar. Overwrite existing files in dir.

httd.args

Further arguments passed to servr::httd.

copy.only

Logical. When TRUE, skip launching the server.

...

Further arguments passed to gexf_js_config.

Details

Currently, the only languages supported are: German (de), English (en), French (fr), Spanish (es), Italian (it), Finnish (fi), Turkish (tr), Greek (el), Dutch (nl)

The server is launched only when interactive() == TRUE and copy.only == FALSE.
