Question

我使用DiagrammeR软件包创建了以下工作流程图。

library(DiagrammeR)
grViz(
  "digraph{
  graph[layout='dot',outputorder=edgesfirst,overlap=T,rankdir=LR]

  b[label='population=BARI_POP4_5_PRIMARY_CN.csv']
  c [label='timepoint=12']
  d[label='endpoint=ACR50']
  b->c[label='']
  c->d[label='']
  }")

我想知道如何将variable_x[1]的{{1}}的{{1}}而不是像下面的“人口”插入

variable_x <- c("population", "timepoint","endpoint")

Answer 1

这是您的主意吗？

variable_x <- c("population", "timepoint", "endpoint")

cat(sprintf("digraph{
  graph[layout='dot',outputorder=edgesfirst,overlap=T,rankdir=LR]

  b[label='%s=BARI_POP4_5_PRIMARY_CN.csv']
  c [label='timepoint=12']
  d[label='endpoint=ACR50']
  b->c[label='']
  c->d[label='']
  }", variable_x[1])
)

输出：

digraph{
  graph[layout='dot',outputorder=edgesfirst,overlap=T,rankdir=LR]

  b[label='population=BARI_POP4_5_PRIMARY_CN.csv']
  c [label='timepoint=12']
  d[label='endpoint=ACR50']
  b->c[label='']
  c->d[label='']
  }
