好看的五套维恩图

Question

在本文中，我最近碰到一个漂亮的5套维恩图来：

我在想，可能是用什么软件来画这个？这可以在R中完成吗？

大多数我看着包似乎产生较少的清晰版

有什么想法？

编辑：似乎使用本网站的工具性质的文章： http://bioinformatics.psb.ugent.be/webtools/Venn/ 仍然可能是不错的它移植到一些[R包，尤其是不对称Venns，这是目前不在，我知道任何封装

Answer 1

对于阿德里安DUSA制成一个非常好的新的R包venn使得维恩如上图，长达7个将记录：

library(venn) 
venn(5, ilab=TRUE, zcolor = "style") 

venn(7, ilab=TRUE, zcolor = "style") 

感谢阿德里安的酷包！

Answer 2

我还在根特生物信息学大学网站上使用了在线维恩图发生器，并且想要我自己的功能。当然，想法是让每个交叉区域的大小合理，以便计数的文本都可以是相同的大小。这里是我的尝试：

fiveCellVenn <- function(colorList=col2rgb(rainbow(5)), 
         cellCounts=seq(1,31,1), 
         cellLabels=c("one","two","three","four","five"), 
         saturation=.25){ 
    rotateVec <-function(vec,amount){ 
    return(c(vec[(amount+1):length(vec)], vec[1:amount])) 
    } 
    n=70 
    xhull <- c() 
    yhull <- c() 
    for (i in 1:n){ 
    xhull <- c(xhull, cos((i*2*pi)/n)) 
    yhull <- c(yhull, sin((i*2*pi)/n)) 
    } 
## The Venn cells begin as a 70-sided regular polygon 
## plot(xhull, yhull) 
## polygon(xhull, yhull) 
## Multiply each unit vector in the hull by a scalar, arrived at by 
## iterative adjustment. 
    adjust <-c(10,10.35,10.6,10.5,10.4,10.3,10.1,9.6,9,8.5, 
      8,7.625,7.25,7.125,7,6.875,6.75,6.875,7,7.125, 
      7.25,7.625,8.1,9.125,10.25,11.375,12.5,13.15,13.8,14.3, 
      14.6,14.725,14.7,14.7,14.7,14.4,14.1,13.8,13.5,12.8, 
      12.1,11.15,10.2,9.6,8.95,8.3,7.7,7,6.25,5.6, 
      5,4.75,4.5,4.25,4,3.8,3.6,3.45,3.45,3.45, 
      3.5,3.625,3.75,3.825,4,4.25,4.5,5.75,7.25,8.5) 
    newxhull <- xhull*adjust 
    newyhull <- yhull*adjust 
## Text location was also done by hand: 
    textLocationX <- c(-13,-3,8,9,-4,-7.5,7.5,-9,-8,4,6.5,-2,9,-4,1.4,4,-7.5,-3.5,7.5,-6,-6.5,6,1.5,4,-0.5,4.5,0,-5,-3.5,3.5,0) 
    textLocationY <- c(1,12,8,-8,-12,6.5,4.5,1,-4,8.5,-6,8.5,-1.5,-8,-9,5,3.5,6,1.5,-6,-1.5,-2,8,-7,-6.5,2,5.5,2,-3.5,-4,0) 
    textLocationMatrix <- matrix(cbind(textLocationX,textLocationY),nrow=31,ncol=2) 
    plot(newxhull, newyhull, pch=".", xlim=c(-16,16), ylim=c(-16,16), 
     axes=FALSE,xlab="",ylab="") 
    newAdjust<-adjust 
    for (i in 1:5){ 
    newxhull <- xhull*newAdjust 
    newyhull <- yhull*newAdjust 
    polygon(newxhull, newyhull, 
      border=rgb(colorList[1,i]/255, colorList[2,i]/255, colorList[3,i]/255, 1), 
      lwd=2, 
      col=rgb(colorList[1,i]/255, colorList[2,i]/255, colorList[3,i]/255,saturation)) 
    newAdjust <- rotateVec(newAdjust,14) 
    } 
    text(textLocationMatrix[,1], textLocationMatrix[,2],labels=as.character(cellCounts)) 
    text(textLocationMatrix[c(17,2,3,24,14),1]*c(2,1.25,1.5,2,2), 
     textLocationMatrix[c(17,2,3,24,14),2]*c(2,1.35,1.5,2,2), 
     labels=cellLabels) 
## uncomment and run to get points and grid for adjusting text location 
## points(textLocationMatrix[,1], textLocationMatrix[,2]) 
## for (i in -16:16){ 
## if (i%%5==0){ 
##  color="black" 
## }else{ 
##  color="lightblue" 
## } 
## abline(v=i,col=color) 
## abline(h=i, col=color) 
## } 
} 

然后

fiveCellVenn() 

产生类似你的第一个维恩。我没有代表发布图片。您可能想要制作颜色并移动单元格名称。
