visNetwork: Network visualization

Description

Network visualization using vis.js library. For full documentation, have a look at visDocumentation.

Usage

visNetwork(
  nodes = NULL,
  edges = NULL,
  dot = NULL,
  gephi = NULL,
  width = NULL,
  height = NULL,
  main = NULL,
  submain = NULL,
  footer = NULL,
  background = "rgba(0, 0, 0, 0)",
  ...
)

Arguments

nodes

: data.frame or a list with nodes informations. Needed at least column "id". See visNodes

• "id" : id of the node, needed in edges information

• "label" : label of the node

• "group" : group of the node. Groups can be configure with visGroups

• "value" : size of the node

• "title" : tooltip of the node

• ...

edges

: data.frame or a list with edges informations. Needed at least columns "from" and "to". See visEdges

• "from" : node id of begin of the edge

• "to" : node id of end of the edge

• "label" : label of the edge

• "value" : size of the node

• "title" : tooltip of the node

• ...

dot

: Character DOT language.

gephi

: Json export gephi path file.

width

: Width (optional, defaults to automatic sizing)

height

: Height (optional, defaults to automatic sizing)

main

: For add a title. Character or a named list.

• "text" : Character. Title.

• "style" : Optional. Character. HTML style of title. Default to 'font-family:Georgia, Times New Roman, Times, serif;font-weight:bold;font-size:20px;text-align:center;'.

submain

: For add a subtitle. Character or a named list.

• "text" : Character. Subtitle.

• "style" : Optional. Character. HTML style of submain. Default to 'font-family:Georgia, Times New Roman, Times, serif;font-size:12px;text-align:center;'.

footer

: For add a footer. Character or a named list.

• "text" : Character. footer.

• "style" : Optional. Character. HTML style of footer. Default to 'font-family:Georgia, Times New Roman, Times, serif;font-size:12px;text-align:center;'.

background

: Background color. Default to 'rgba(0, 0, 0, 0)' (transparent). Can be a valid color name ("red"), a HEX value ("#ff0000") or rgb/rgba ("rgb(255,0,0)")

...

: Don't use.
