半透明的维恩图比例和颜色阴影 [英] Venn diagram proportional and color shading with semi-transparency

问题描述

我有以下类型的计数数据.

A 450乙 1800A 和 B 均为 230

我想开发一个像下面的维恩图一样的彩色(交叉点可能是半透明的).

注意:此图是在 PowerPoint 中手绘的示例，不按比例绘制.

解决方案

这是一篇讨论 .>

库(维恩图)venn.diagram(list(B = 1:1800, A = 1571:2020), fill = c("lightblue", "green"),alpha = c(0.5, 0.5), lwd =0, "venn_diagram.tiff")

I have following type of count data.

A   450
B   1800
A and B both    230

I want to develop a colorful (possibly semi-transparency at intersections) like the following Venn diagram.

Note: This figure is an example hand drawn in PowerPoint, and it is not to scale.

解决方案

Here is a post which discusses Venn diagram from list of clusters and co-occurring factors.

For easy solution use package venneuler:

require(venneuler)
v <- venneuler(c(A=450, B=1800, "A&B"=230))
plot(v)

For more advanced and customized solutions check package VennDiagram.

library(VennDiagram) 
venn.diagram(list(B = 1:1800, A = 1571:2020), fill = c("lightblue", "green"), 
             alpha = c(0.5, 0.5), lwd =0, "venn_diagram.tiff")
