Rで解析：インタラクティブなネットワーク図「networkD3」パッケージ

#パッケージのインストール
install.packages("networkD3")

#パッケージの読み込み
library("networkD3") #ネットワーク図作成に必要
library("magrittr") #HTMLで出力するのに必要

###シンプルなネットワーク図の作成#####

#データの準備
src <- c("A", "A", "A", "A", "B", "B", "C", "C", "D")
target <- c("B", "C", "D", "J", "E", "F", "G", "H", "I")
networkData <- data.frame(src, target)

#グラフのプロット
simpleNetwork(networkData, width = NULL, height = NULL, fontSize = 20,
              textColour = "blue", linkColour = "red",
              nodeColour = "green", opacity = 1, charge = -200)

#グラフを作業フォルダに保存
NwtworkPlot <- simpleNetwork(networkData, width = NULL, height = NULL, fontSize = 20,
                                textColour = "blue", linkColour = "red",
                                nodeColour = "green", opacity = 1, charge = -200)
saveNetwork(network = NwtworkPlot , file = 'simple.html', selfcontained = TRUE)
