使用VennDiagram包缩放R中的三重维恩图 [英] scaling triple Venn diagram in R with VennDiagram package

问题描述

有人知道如何获取R包VennDiagram来根据集合大小缩放包含3个相交集合的Venn图的圆吗?

Does anyone know how to get the R package VennDiagram to scale the circles of a Venn diagram containing 3 intersecting sets according to set size?

我可以通过Venneular软件包实现这种缩放，但是与VennDiagram相比，在其他图形选项方面我发现这有点限制.

I can achieve such scaling with the venneular package, but I find this a bit limited in terms of other graphical options compared to VennDiagram.

VennDiagram软件包文档建议将参数"scaled"设置为TRUE应该可以解决问题，但是我发现这会产生3个相等大小的圆.

The VennDiagram package documentation suggests setting the argument 'scaled' to TRUE ought to do the trick, but I find this produces 3 circles of equal size.

软件包文档确实暗中暗示了scaled参数仅适用于某些图表:

The package documentation does cryptically suggest that the scaled argument may only work for certain diagrams:

?draw.triple.venn

显示:

已缩放: 布尔值，指示是否根据设置的大小缩放某些欧拉图中的圆的大小"

scaled: "Boolean indicating whether to scale circle sizes in certain Euler diagrams according to set sizes or not"

和

?venn.diagram

#Argument Venn Sizes    Class    Description
#scaled    2, 3         logical  Enable scaling for two-set and certain three-set Euler diagrams.

我的代码的一个玩具示例:

A toy example of my code:

require(VennDiagram)

venn.plot <- draw.triple.venn(
    area1 = 70,
    area2 = 250,
    area3 = 500,
    n12 = 30,
    n23 = 60,
    n13 = 10,
    n123 = 5,
    category = c("C1", "C2", "C3"),
    fill = c("blue", "red", "green"),
    scaled=TRUE)

tiff(filename = "test.tiff", compression = "none",type = "quartz",antialias = "none")
grid.draw(venn.plot)
dev.off()

类似地，使用"venn.diagram"功能的此代码不会产生所需的缩放比例:

Similarly this code using the 'venn.diagram' function doesn't produce the required scaling:

venn.diagram(x=list(A=c(1:15,16:20), B=c(6:15,21:30,100:150), C=c(11:30,200:300)),
         filename="test.tiff",
         fill = c("blue", "yellow", "red"), scaled=TRUE)

非常感谢

推荐答案

所以要回答我自己的问题: 对于某些配置，从数学上讲不可能创建一个 用圆按比例缩放三向维恩.

So to answer my own question: for certain configurations it is mathematically impossible to create a scaled 3-way Venn using circles.
