Try this:
x1=c(0.6,0.4,.4,.4,.2,.2,.2,0,0)
x2=c(0.4,.2,.4,.6,0,.2,.4,0,.2)
x1=rep(x1,4)
x2=rep(x2,4)
temp=data.frame(x1,x2)
foo <- subset(as.data.frame(table(temp)), Freq > 0)
foo$x1 <- as.numeric(as.character(foo$x1))
foo$x2 <- as.numeric(as.character(foo$x2))
with(foo, plot(x1, x2, type = "n"))
with(foo, text(x1, x2, lab = Freq))
