r - 在R中创建组织结构图

Question

我需要在R中绘制公司的组织结构图。我有一个示例，但我希望箭头也指向同一点。

我的期望（来自PowerPoint）：



我得到的（在R中）：



码：

grViz("
  digraph {

  graph[splines=ortho, nodesep=1]

  node[shape=box]
  President;Fun1;Fun2;Fun3;

  President->{Fun1,Fun2,Fun3}
  }
  ")

Answer 1

您需要利用空白/空节点，类似这样（如果您不希望箭头将[dir = none]添加到最后一行，例如（blank_3 -> Fun1 [dir = none]）：

library(DiagrammeR)

grViz("
  digraph {

  node[shape=box, width = 4, height = 1]

  blank_1 [label = '',color = white];
  President;
  blank_2 [label = '',color = white];

  blank_3[label = '', width = 0.01, height = 0.01];
  blank_4[label = '', width = 0.01, height = 0.01];
  blank_5[label = '', width = 0.01, height = 0.01];

  Fun1;
  Fun2;
  Fun3;

  {rank = same; blank_1 President blank_2}
  {rank = same; blank_3 blank_4 blank_5}
  {rank = same; Fun1 Fun2 Fun3}

  blank_1 -> President [dir = none, color = White]
  President -> blank_2 [dir = none, color = White]
  President -> blank_4 [dir = none]
  blank_1 -> blank_3 [dir = none, color = White]
  blank_2 -> blank_5 [dir = none, color = White]
  blank_3 -> blank_4 [dir = none]
  blank_4 -> blank_5 [dir = none]
  blank_3 -> Fun1
  blank_4 -> Fun2
  blank_5 -> Fun3

   }
 ")
