Build Many Element With data.frame • shinyCyJS

If small amount of nodes / edges are needed to be plotted, using buildNode and buildEdge will fine. However in most case, almost ~ 100 element or more should be plotted.

Which is not efficient with repetitive using of buildNode and buildEdge.

buildElem is function for that case, which build uniform elements(only node or only edge).

library(shinyCyJS)

These 2 code will return same results. (nevermind layout, it contains randomness)

  shinyCyJS(list(
    buildNode('a'),
    buildNode('b', width = 20),
    buildNode('c', width = 30),
    buildNode('d', width = 40),
    buildEdge('a','b'),
    buildEdge('a','c'),
    buildEdge('c','d'),
    buildEdge('b','d')
    ))

  a = data.frame(
    id = c('a','b','c','d'),
    width = c(15,20,30,40)
  )

  b = data.frame(
    source = c('a','a','c','b'),
    target = c('b','c','d','d')
  )

  nodes = buildElems(a,'Node')
  edges = buildElems(b,'Edge')

  shinyCyJS(c(nodes, edges))
