gexf_js_config: Visualizing GEXF graph files using gexf-js (legacy)

Description

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.
