一：利用函数draw.pairwise.venn绘制两个集合的韦恩图
draw.pairwise.venn(area1=Length_A,area2=Length_B,cross.area=Length_AB,category=c('A','B'),
lwd=rep(1,1) #边框线宽度,
lty=rep(2,2) #lty设定圆弧的线型,
col=c('red','green') #边框颜色,
alpha = 0.7 #透明度,
fill=c('red','green') #填充色 ,
cex = 1 #标签字体大小,
margin = 0.01 #边际距离,
cat.col=c('red','green') #表示集合名称的显示颜色,r
otation.degree=180) #调整图形的旋转角度。

二：利用函数 draw.triple.venn绘制三个集合的韦恩图
draw.triple.venn(
area1=Length_A, area2=Length_B, area3=Length_C #area1、area2、area3分别指第一个、第二个、第三个集合的大小,
n12=Length_AB, n23=Length_BC, n13=Length_AC, n123=Length_ABC #n12表示第一个与第二个集合的交集大小，n23、n13也是类似，n123指三个集合的交集大小,
category = c('A','B','C') #指定集合名称,col=c('red','green','blue') #边框颜色,
fill=c('red','green','blue') #填充色,
cat.col=c('red','green','blue') #表示集合名称的显示颜色,
reverse = FALSE) #指是否对图形进行反转。

三：利用函数 draw.quad.venn绘制四个集合的韦恩图
draw.quad.venn(
area1=Length_A, area2=Length_B, area3=Length_C, area4=Length_D,
n12=Length_AB, n13=Length_AC, n23=Length_BC, n14=Length_AD, n24=Length_BD , n34=Length_CD,
n123=Length_ABC, n124=Length_ABD, n234=Length_BCD, n134=Length_ACD,
n1234=Length_ABCD ,category = c('A','B','C','D') ,
col=c('red','green','blue','orange'), fill=c('red','green','blue','orange') ,
alpha = 0.7 ,
lty=rep(4), cat.col=c('pink') ,
reverse = FALSE)

area1=Length_A, area2=Length_B, area3=Length_C, area4=Length_D, area5=Length_E,
n12=Length_AB, n13=Length_AC, n14=Length_AD, n15=Length_AE, n23=Length_BC, n24=Length_BD, n25=Length_BE, n34=Length_CD, n35=Length_CE, n45=Length_DE,
n123=Length_ABC, n124=Length_ABD, n125=Length_ABE , n234=Length_BCD, n235=Length_BCE, n245=Length_BDE, n134=Length_ACD,n135=Length_ACE,n145=Length_ADE, n345=Length_CDE ,
n1234=Length_ABCD,n1235=Length_ABCE ,n1245=Length_ABDE, n1345=Length_ACDE, n2345=Length_BCDE,
n12345=Length_ABCDE, category = c('A','B','C','D','E') ,
