计算重叠后打印维恩图

Question

我正在尝试使用VennDiagram包中的calculate.overlap函数来首先计算并打印维恩图。我能够计算我的数据集的重叠，但寻找帮助如何打印维恩图形。有人可以提供帮助吗？我仔细阅读了文档，但没有找到。

> library('VennDiagram')

# A simple single-set diagram
cardiome <- letters[1:10]
superset <- letters[8:24]
overlap <- calculate.overlap(
x = list(
"Cardiome" = cardiome,
"SuperSet" = superset
)
);

Answer 1

功能venn.diagram()可以做到。例如在你的例子中

venn.diagram(x = list(
  "Cardiome" = cardiome,
  "SuperSet" = superset
), "plot_venn")

它保存到工作目录。输入getwd()以查看其设置的内容。

参见

?venn.diagram()

Answer 2

另一个简单示例，演示如何使用VennDiagram包打印维恩图：

library(VennDiagram)
cardiome <- letters[1:10]
superset <- letters[8:24]
overlap <- calculate.overlap(
x <- list("Cardiome"=cardiome, "SuperSet"=superset))

venn.plot <- draw.pairwise.venn(
    area1 = length(cardiome),
    area2 = length(superset),
    cross.area = length(overlap),
    category = c("Cardiome", "Superset"),
    fill = c("blue", "red"),
    lty = "blank",
    cex = 2,
    cat.cex = 2,
    cat.pos = c(180, 180),
    cat.dist = 0.05,
    cat.just = list(c(0, 1), c(1, 1))
    )
grid.draw(venn.plot)
savePlot(filename="venndiag", type="png")

在集合中带有项目标签的维恩图：

library(RAM)
vectors <- list(Cardiome=cardiome, Superset=superset)
group.venn(vectors=vectors, label=TRUE, 
    fill = c("blue", "red"),
    cat.pos = c(180, 180),
    lab.cex=1.1)

Answer 3

?venn.diagram建议这个

library('VennDiagram')
venn.plot <- venn.diagram(
  x = list(
    cardiome = letters[1:10],
    superset = letters[8:24]
  ),
  filename = NULL
);
grid.draw(venn.plot);
