如何在R中使用draw.pairwise.venn更改维恩图的背景色？

install.packages("VennDiagram")

library(VennDiagram)

# 创建示例数据
set.seed(123)
group1 <- sample(1:100, 50)
group2 <- sample(1:100, 50)
group3 <- sample(1:100, 50)

# 绘制维恩图
venn.diagram(
  x = list(A = group1, B = group2, C = group3),
  filename = NULL,
  col = "transparent",  # 设置背景色为透明
  fill = c("cornflowerblue", "green", "yellow"),  # 设置区域颜色
  alpha = 0.5,  # 设置区域透明度
  label.col = c("orange", "white", "darkblue"),
  cex = 1.5,
  fontfamily = "serif",
  fontface = "bold",
  cat.col = c("cornflowerblue", "green", "yellow"),
  cat.cex = 1.2,
  cat.fontfamily = "serif",
  cat.fontface = "bold",
  margin = 0.05
)
