韦恩图
韦恩图主要用于集合的计算，计算不同集合之间的交集，并集，补集等。可以绘制 2-7 个集合的运算，图形可以用圆形或者椭圆形表示。library(venn)
listA <- read.csv("genes_list_A.txt",header=FALSE)

venn(list(A,B,C,D,E,F,G,H),zcolor = rainbow(6))#画不了，只能画7个，一般5个最多了
#这个时候可以百度下花瓣图，聚焦交集。
venn(list(A,B,C,D),zcolor = rainbow(4))
h <- venn(list(A,B,C,D),zcolor = rainbow(4))
