如何在r中使用calculate.overlap函数查找与维恩图的哪些部分相关的元素? [英] How to find which elements related to which parts of venn diagram using calculate.overlap function in r?

问题描述

calculate.overlap的输出不清楚. 维恩图的每个位置都有一些名称，例如:$ a1，$ a2，... 当我们画出五个清单时，它变得如此复杂. 如何识别哪些名称($ a1，$ a2，...)与哪些列表的重叠有关?

The output of calculate.overlap is not clear. There are some names for each position of venn diagram such as: $a1 , $a2 , ... It becomes so complicated when we draw it for five list. How to recognize which names ($a1 , $a2 , ...) related to the overlap of which lists?

library(VennDiagram)

overlap=calculate.overlap(
    x=list(
        "A"=c("a","b","c"),
        "B"=c("a","b","c","d"),
        "C"=c("a","c","d")
    )
)

这是输出:

$a5
[1] "a" "c"

$a2
[1] "b"

$a4
character(0)

$a6
[1] "d"

$a1
character(0)

$a3
character(0)

$a7
character(0)

如何用我的列表名称替换这些名称?

How to replace these names with the names of my list?

我的预期输出是:

$A,B,C
[1] "a" "c"

$A,B
[1] "b"

$A,C
character(0)

$B,C
[1] "d"

$A
character(0)

$B
character(0)

$C
character(0)

There is an answer here. However, I do not claim to understand it. The general rule to order the regions in a Venn diagram is to use a binary representation of it. My nVennR package uses that representation and can give you a quick answer for any number of sets:

> library(nVennR)
> myV <- plotVenn(list("A"=c("a","b","c"), "B"=c("a","b","c","d"), "C"=c("a","c","d")), showPlot = F)
> listVennRegions(myV)
$`0, 1, 1 (B, C)`
[1] "d"

$`1, 1, 0 (A, B)`
[1] "b"

$`1, 1, 1 (A, B, C)`
[1] "a" "c"

> listVennRegions(myV, na.rm = F)
$`0, 0, 0 ()`
[1] NA

$`0, 0, 1 (C)`
[1] NA

$`0, 1, 0 (B)`
[1] NA

$`0, 1, 1 (B, C)`
[1] "d"

$`1, 0, 0 (A)`
[1] NA

$`1, 0, 1 (A, C)`
[1] NA

$`1, 1, 0 (A, B)`
[1] "b"

$`1, 1, 1 (A, B, C)`
[1] "a" "c"
