我正在尝试使用R和DiagrammeR制作SEM图。我已经设置好图表,但是我试图在图表底部设置一些节点(CSEW,ONS和Police),以使其更易于阅读。
这是我到目前为止所拥有的。欢迎提出任何有关将三个圆圈移至底部的建议。
library(DiagrammeR)
grViz("
digraph MTMM {
subgraph {
node [shape = box, fixedsize = true, width = 1]
rank = same; bike_c; bike_p; bike_o
burg_c; burg_p; burg_o
theft_c; theft_p; theft_o
viol_c; viol_p; viol_o
}
subgraph {
node [shape = circle, fixedsize = true, width = 1]
Bicycle; Burglary; Theft; Violence
}
subgraph {
node [shape = circle, fixedsize = true, width = 1]
CSEW; ONS; Police
}
Bicycle -> {bike_c bike_p bike_o}
Burglary -> {burg_c burg_p burg_o}
Theft -> {theft_c theft_p theft_o}
Violence -> {viol_c viol_p viol_o}
CSEW -> {bike_c burg_c theft_c viol_c} [label = '1']
ONS -> {bike_o burg_o theft_o viol_o} [label = '1']
Police -> {bike_p burg_p theft_p viol_p} [label = '1']
{rank = same; CSEW; ONS; Police}
{rank = same; Bicycle; Burglary; Theft; Violence}
}
")
答案 0 :(得分:1)
如果要在节点A
上方有节点B
,则必须从A -> B
指向,这是graphviz的基本逻辑。如果希望箭头指向另一个方向,可以通过告诉graphviz:A -> B[ dir = back]
。
在您的情况下,将三行替换为
{bike_c burg_c theft_c viol_c} -> CSEW [dir = back, label = '1']
{bike_o burg_o theft_o viol_o} -> ONS[dir = back, label = '1']
{bike_p burg_p theft_p viol_p} -> Police[dir = back, label = '1']
给你
