> library (VennDiagram)

具體畫(huà)法可通過(guò)help（VennDiagram）學(xué)習(xí)

例如：

##生成四個(gè)不同的組合

> A<- sample(LETTERS, 18, replace = FALSE)

> B<- sample(LETTERS, 20, replace = FALSE)

> C<- sample(LETTERS, 22, replace = FALSE)

> D<- sample(LETTERS, 19, replace = FALSE)

##使用venn.diagram功能繪圖

> venn.diagram(x =list(A = A,D = D,B = B,C = C), filename = "My5.png", height = 450, width= 450, resolution =300, imagetype="png", lwd=0.6, fill =c("cornflowerblue","green","yellow","darkorchid1"),cex=0.45, cat.cex=0.45)
