Why my circles with no overlap isolated from others? I want to show there is no overlap between them, but the triple shape of venn diagram completely have changed with mix of two circles and one. I need mixed circles together.

a1<-c("a","b")
a2<- c("a","b","c")
a3<- c("x","y")
x<-list(a1,a2,a3)
venn.diagram(x, "test.tiff",category.names=c("a1","a2","a3"))

This is my venn diagram chart: enter image description here

Instead of using the VennDiagram package, you can get the desired result with gplots. You just need to name the list.

library(gplots)

a1<-c("a","b")
a2<- c("a","b","c")
a3<- c("x","y")
x<-list(a1,a2,a3)

# New lines
names(x) = c("a1","a2","a3")
venn(x)

This will give you the following plot:
