使用DiagrammeR以编程方式生成Consort图的R代码？

Question

我想以编程方式创建一个描述患者在随机试验中流动的Consort图。

有没有人有R代码使用DiagrammeR生成此图（请参阅下面的链接）？

Answer 1

5年前在计算器以前问。答案用包图： creating tree diagram for showing case count using R

谷歌发现了一些graphviz的代码： http://blogs.sas.com/content/graphicallyspeaking/2016/10/20/outside-box-consort-diagram/

RStudio可以直接预览的Graphviz .dot文件：

另外，

library(DiagrammeR) 
consort <- file("consort.dot") 
grViz(diagram = consort) 
close(consort) 

“consort.dot”如下：

digraph g { 
start [shape = box, label = "CONSORT Graph"]; 
node0 [shape = box, label = "All Patients\nN=1000"]; 
node1 [shape = box, label = "Full Analysis Set\nN=800"]; 
node2 [shape = box, label = "Excluded\nN=100"]; 
node3 [shape = box, label = "Not Included\nN=100"]; 
node4 [shape = box, label = "Safety Set\nN=700"]; 
node5 [shape = box, label = "Not Dosed\nN=100"]; 
node6 [shape = box, label = "Treatment A\nN=200"]; 
node7 [shape = box, label = "Treatment B\nN=150"]; 
node8 [shape = box, label = "Treatment C\nN=200"]; 
node9 [shape = box, label = "Treatment D\nN=150"]; 
start -> node0 -> node1 -> node4 -> {node6 node7 node8 node9}; 
node0 -> node2; 
node0 -> node3; 
node1 -> node5; 
}
