# Re: [R] plot the number of replicates at the same point

You may test the following example:

```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)
temp1=table(temp)
plot(temp\$x1,temp\$x2,cex=0)
text(as.numeric(rownames(temp1)),
as.numeric(colnames(temp1)), temp1)

I actually want some plots similar to what SAS proc plot produced.

Does anybody have a clue of how to do this easily in R?
