FigDraw 9. SCI 文章绘图之韦恩图 (Vennplo

这期来聊聊韦恩图，这种图形虽然简单，但是也是文章中很常见的，今天就来看看 CNS 级别文章中的Venn该怎么绘制？

前言

维恩图用于展示在不同的事物群组（集合）之间的数学或逻辑联系，尤其适合用来表示集合（或）类之间的“大致关系”，它也常常被用来帮助推导（或理解推导过程）关于集合运算（或类运算）的一些规律。一般个数在2到7组之间。

我们希望实现下面的韦恩图以及更高维度的图形。

1. 软件包安装

if (!require(VennDiagram)) install.packages("VennDiagram")
if (!require(venn)) install.packages("venn")
if (!require(UpSetR)) install.packages("UpSetR")

library(VennDiagram)
library(venn)
library(UpSetR)

2. 数据读取

该模块支持2种数据格式，下面是详细介绍:

韦恩图常用数据格式：第一行为组名，必须要有，会出现在图中。每一列都是一个分组。
定量矩阵表格式：每行是一个基因，每列是个样本。行名和列名都要有，数值是定量值。

我们使用的第一种格式，如下：

dat <- read.table("flower.txt", header = T, sep = "\t")
head(dat)
##         c1       c2       c3       c4       c5       c6       c7       c8
## 1 gene1193 gene1253 gene1236 gene1325 gene1246 gene1414 gene1259 gene1249
## 2 gene1194 gene1254 gene1241 gene1327 gene1247 gene1416 gene1260 gene1250
## 3 gene1195 gene1255 gene1243 gene1328 gene1248 gene1417 gene1261 gene1251
## 4 gene1197 gene1256 gene1244 gene1329 gene1249 gene1421 gene1262 gene1253
## 5 gene1199 gene1257 gene1246 gene1330 gene1250 gene1422 gene1263 gene1256
## 6 gene1202 gene1259 gene1247 gene1331 gene1251 gene1425 gene1265 gene1258
dim(dat)
## [1] 1662    8
venn_list = as.list(dat[, -8])
# 查看交集详情,并导出结果

3. 绘制多集合韦恩图

这里我们使用两个软件包 venn 和 VennDiagram 都是经典的绘制Venn图非常棒的软件包，其中Venn能实现2-7个集合的韦恩图绘制，而VennDiagram可以实现2-5个集合的韦恩图，两者都有自己的风格，集合过多就不适合这么做了，羡慕的例子可别适合做转录组多分组比较之后的差异基因集合个数，有想做这种分析的，一定参照这些例子，做出图形非常美观！注意：venn在做韦恩图时候自始至终都是一个函数venn；而VennDiagram每次不同的集合个数都需要变换函数，而且需要自己统计好交集的个数，2-3个集合还算好弄，但是高于4个集合，自己统计起来还是挺麻烦的，需要自己搞个脚本循环一下。另外高于7个集合的这需要另种表现形式，可以通过 UpSetR 软件包来实现。

2. 两个集合韦恩图

两个集合的韦恩图最常见也是做好理解和绘制的，我们同样使用两个软件包来实现绘制功能，如下：

A. venn {venn}

venn函数的输入数据为列表，所以我们需要将数据框转为列表，直接使用as.list()函数即可，如下：

venn2List <- as.list(dat[,1:2])

cross=venn(venn2List,
     zcolor='style', # 调整颜色，style是默认颜色，bw是无颜色，当然也可以自定义颜色
     opacity = 0.3,  # 调整颜色透明度
     box = F,        # 是否添加边框
     ilcs = 0.5,     # 数字大小
     sncs = 1        # 组名字体大小
)

B. draw.pairwise.venn {VennDiagram}

创建一个包含两个集合的维恩图。当数据集满足特定条件时创建欧拉图。

cross
##       c1 c2 counts
##        0  0      0
## c2     0  1    756
## c1     1  0    777
## c1:c2  1  1    885
venn.plot <- draw.pairwise.venn(area1 = sum(cross[cross$c1 == 1, ]$counts), area2 = sum(cross[cross$c2 ==
    1, ]$counts), cross.area = sum(cross[which(grepl("c1:c2", rownames(cross)) ==
    TRUE), ]$counts), category = colnames(dat[, 1:2]), fill = c("blue", "red"), lty = "blank",
    cex = 2, cat.cex = 2, cat.pos = c(285, 105), cat.dist = 0.09, cat.just = list(c(-1,
        -1), c(1, 1)), ext.pos = 30, ext.dist = -0.05, ext.length = 0.85, ext.line.lwd = 2,
    ext.line.lty = "dashed")

3. 三个集合韦恩图

A. venn {venn}

venn3List <- as.list(dat[,1:3])

cross=venn(venn3List,
     zcolor='style', # 调整颜色，style是默认颜色，bw是无颜色，当然也可以自定义颜色
     opacity = 0.3,  # 调整颜色透明度
     box = F,        # 是否添加边框
     ilcs = 0.5,     # 数字大小
     sncs = 1        # 组名字体大小
)

B. draw.triple.venn {VennDiagram}

创建一个包含三个集合的维恩图。当数据集满足特定条件时创建欧拉图。

cross
##          c1 c2 c3 counts
##           0  0  0      0
## c3        0  0  1    477
## c2        0  1  0    596
## c2:c3     0  1  1    160
## c1        1  0  0    581
## c1:c3     1  0  1    196
## c1:c2     1  1  0    255
## c1:c2:c3  1  1  1    630
venn.plot <- draw.triple.venn(area1 = sum(cross[cross$c1 == 1, ]$counts), area2 = sum(cross[cross$c2 ==
    1, ]$counts), area3 = sum(cross[cross$c3 == 1, ]$counts), n12 = sum(cross[which(grepl("c1:c2",
    rownames(cross)) == TRUE), ]$counts), n23 = sum(cross[which(grepl("c2:c3", rownames(cross)) ==
    TRUE), ]$counts), n13 = sum(cross[which(grepl("c1:c3", rownames(cross)) == TRUE),
    ]$counts) + cross["c1:c2:c3", ]$counts, n123 = sum(cross[which(grepl("c1:c2:c3",
    rownames(cross)) == TRUE), ]$counts), category = colnames(dat[, 1:3]), fill = c("blue",
    "red", "green"), lty = "blank", cex = 2, cat.cex = 2, cat.col = c("blue", "red",
    "green"))

4. 四个集合韦恩图

A. venn {venn}

venn4List <- as.list(dat[,1:4])
cross=venn(venn4List,
     zcolor='style', # 调整颜色，style是默认颜色，bw是无颜色，当然也可以自定义颜色
     opacity = 0.3,  # 调整颜色透明度
     box = F,        # 是否添加边框
     ilcs = 0.5,     # 数字大小
     sncs = 1        # 组名字体大小
)

B. draw.quad.venn {VennDiagram}

创建一个包含四个集合的维恩图。

cross

## c4           0  0  0  1    368

## c2           0  1  0  0    507
## c2:c4        0  1  0  1     89
## c2:c3        0  1  1  0    104
## c2:c3:c4     0  1  1  1     56
## c1           1  0  0  0    494
## c1:c4        1  0  0  1     87
## c1:c3        1  0  1  0    114
## c1:c3:c4     1  0  1  1     82
## c1:c2        1  1  0  0    159
## c1:c2:c4     1  1  0  1     96
## c1:c2:c3     1  1  1  0    179
## c1:c2:c3:c4  1  1  1  1    451
venn.plot <- draw.quad.venn(area1 = sum(cross[cross$c1 == 1, ]$counts), area2 = sum(cross[cross$c2 ==
    1, ]$counts), area3 = sum(cross[cross$c3 == 1, ]$counts), area4 = sum(cross[cross$c4 ==
    1, ]$counts), n12 = sum(cross[which(grepl("c1:c2", rownames(cross)) == TRUE),
    ]$counts), n13 = sum(cross[which(grepl("c1:c3", rownames(cross)) == TRUE), ]$counts) +
    179 + 451, n14 = sum(cross[which(grepl("c1:c4", rownames(cross)) == TRUE), ]$counts) +
    96 + 451, n23 = sum(cross[which(grepl("c2:c3", rownames(cross)) == TRUE), ]$counts),

        rownames(cross)) == TRUE), ]$counts), n1234 = sum(cross[which(grepl("c1:c2:c3:c4",
        rownames(cross)) == TRUE), ]$counts), category = colnames(dat[, 1:4]), fill = c("orange",
        "red", "green", "blue"), lty = "dashed", cex = 2, cat.cex = 2, cat.col = c("orange",
        "red", "green", "blue"))

5. 五个集合韦恩图

A. venn {venn}

venn5List <- as.list(dat[,1:5])
cross=venn(venn5List,
     zcolor='style', # 调整颜色，style是默认颜色，bw是无颜色，当然也可以自定义颜色
     opacity = 0.3,  # 调整颜色透明度
     box = F,        # 是否添加边框
     ilcs = 0.5,     # 数字大小
     sncs = 1        # 组名字体大小
)

B. draw.quintuple.venn {VennDiagram}

创建带有五个集合的维恩图。

venn.plot <- draw.quintuple.venn(area1 = 301, area2 = 321, area3 = 311, area4 = 321,
    area5 = 301, n12 = 188, n13 = 191, n14 = 184, n15 = 177, n23 = 194, n24 = 197,
    n25 = 190, n34 = 190, n35 = 173, n45 = 186, n123 = 112, n124 = 108, n125 = 108,
    n134 = 111, n135 = 104, n145 = 104, n234 = 111, n235 = 107, n245 = 110, n345 = 100,
    n1234 = 61, n1235 = 60, n1245 = 59, n1345 = 58, n2345 = 57, n12345 = 31, category = colnames(dat[,
        1:5]), fill = c("dodgerblue", "goldenrod1", "darkorange1", "seagreen3", "orchid3"),
    cat.col = c("dodgerblue", "goldenrod1", "darkorange1", "seagreen3", "orchid3"),
    cat.cex = 2, margin = 0.05, cex = c(1.5, 1.5, 1.5, 1.5, 1.5, 1, 0.8, 1, 0.8,
        1, 0.8, 1, 0.8, 1, 0.8, 1, 0.55, 1, 0.55, 1, 0.55, 1, 0.55, 1, 0.55, 1, 1,
        1, 1, 1, 1.5), ind = TRUE)

6. 六个集合维恩图

venn {venn}

venn6List <- as.list(dat[,1:6])
venn(venn6List,
     zcolor='style', # 调整颜色，style是默认颜色，bw是无颜色，当然也可以自定义颜色
     opacity = 0.3,  # 调整颜色透明度
     box = F,        # 是否添加边框
     ilcs = 0.5,     # 数字大小
     sncs = 1        # 组名字体大小
)

7. 七个集合韦恩图

venn {venn}

venn7List <- as.list(dat[,1:7])
cross=venn(venn7List,
     zcolor='style', # 调整颜色，style是默认颜色，bw是无颜色，当然也可以自定义颜色
     opacity = 0.3,  # 调整颜色透明度
     box = F,        # 是否添加边框
     ilcs = 0.5,     # 数字大小
     sncs = 1        # 组名字体大小
)

8. 多于7个集合的韦恩图

多于7个基本就实现不了这种带曲圆的方式绘制了，但是可以考虑通过UpSetR软件包中upset来实现一个热点表格的形式展现，我们先绘制8个集合的图形，如下：

require(ggplot2)
require(plyr)
require(gridExtra)
require(grid)
movies <- read.csv(system.file("extdata", "movies.csv", package = "UpSetR"), header = TRUE,
    sep = ";")
upset(movies, nsets = 8, nintersects = 30, mb.ratio = c(0.5, 0.5), order.by = c("freq",
    "degree"), decreasing = c(TRUE, FALSE))

绘制9个集合的图形，如下：

upset(movies, nsets = 9, nintersects = 30, mb.ratio = c(0.5, 0.5), order.by = c("freq",
    "degree"), decreasing = c(TRUE, FALSE))

绘制10个集合的图形，如下：

upset(movies, nsets = 10, nintersects = 30, mb.ratio = c(0.5, 0.5), order.by = c("freq",
    "degree"), decreasing = c(TRUE, FALSE))

最后看看整体炫图，还是蛮酷毙了的赶脚！
