在R（Vennerable包装）中的维恩图上绘制重量和％

Question

我遇到一些麻烦/我需要绘制维恩图并一起打印重量值和百分比。 现在，我正在编写以下代码：

library(Vennerable)
> areas
   00    01    10    11 
38596  6024 40696  8971
VennSet <- Venn(SetNames = category, Weight = areas)
VennList <- compute.Venn(VennSet, doWeights = TRUE)
gp <- VennThemes(VennList)
plot(VennList, gpList=gp, show = list(FaceText = c("signature", "weight"), DarkMatter = TRUE))

结果：

然后，我想更改最后一行中的值。

pcentFun <- function(x) {
100 * (x /sum(x))
}
areasPcent <- round(pcentFun(areas), digits=2)
VennList@FaceLabels$Signature <- paste(areasPcent, "%", sep="")

结果：

我已经打印了百分比，但是却瘦了。 这是对象的结构：

及其输出

谁知道如何输出权重和百分比？

Answer 1

这不是我想要的。 但也有生存的权利。

areasPcent <- round(pcentFun(areas), digits=2)
VennSet <- Venn(SetNames = category, Weight = areas)
VennList <- compute.Venn(VennSet, doWeights = TRUE)
VennList_pc <- VennList
for (i in c(1:length(areasPcent))) {
    position <- grep(names(areasPcent)[i], VennList_pc@FaceLabels$Signature)
    VennList_pc@FaceLabels$Signature[position] <- paste(areasPcent[i], "%", sep="")
}
gp <- VennThemes(VennList)
pdf(file=file.path(paste("Venn Diagram between ", v2, " from ", v1, ".pdf", sep="")), width=8, height=12.76)
par(mfrow=c(1, 2))
par(mai=c(0.7, 0.7, 0.7, 0.5))
rowNumberMakevp <<- 1
plot(VennList, gpList=gp)
rowNumberMakevp <<- 2
plot(VennList_pc, gpList=gp, show = list(FaceText = c("signature"), DarkMatter = TRUE))
dev.off()

我正在使用R中的Vennerable从并排的维恩图使用多个图的解决方案

Answer 2

尽管这个问题是在几年前提出的，但我认为最好分享对我有用的答案。 实际上，我发现了一种更简单的方法（在areas和areasPcent使用换行符），如下所示：

VennList@FaceLabels$Signature <- paste0(areas, "\n", areasPcent, "%")
plot(VennList, gpList=gp, show = list(FaceText = c("signature"), DarkMatter = TRUE))

注意，您只需要在FaceText显示"signature" 。

希望能帮助到你。
