一、画Venn diagram
1、依赖包
library(venn)
2、安装venn包
(1)方式一:install.packages(venn)
(2)方式二:在https://cran.r-project.org/src/contrib/Archive/下载离线安装包,然后通过Rstudio->Tools->Install Packages->Browse选中本地离线安装包
3、画venn图
library(venn)
# 随机初始化数据集
rand_1 <- sample(1:1000, 400, replace = FALSE);
rand_2 <- sample(1:1000, 600, replace = FALSE);
rand_3 <- sample(1:1000, 350, replace = FALSE);
rand_4 <- sample(1:1000, 550, replace = FALSE);
rand_5 <- sample(1:1000, 375, replace = FALSE);
rand_6 <- sample(1:1000, 200, replace = FALSE);
dataForVennDiagram <- list(
rand_1,
rand_2,
rand_3,
rand_4,
rand_5,
rand_6
)
# 画venn diagram
venn(
dataForVennDiagram,
snames = c("r-1", "r-2", "r-3", "r-4", "r-5", "r-6"), # 重命令
zcolor = "style", # add color
opacity = 0.25,
ellipse = F
)
4、Venn效果图
注意:画出这种效果一般要求集合至少6个,如果集合小于5个,美观度没有这个好
