R help - Jul 2005 - plot the number of replicates at the same point

Dear R-helper,
  I want to plot the following-like data:

x y
1 1
1 1
1 2
1 3
1 3
1 4
......

In the plot that produced, I don't want to show the
usual circles or points. Instead, I want to show the
number of replicates at that point. e.g. at the
position of (1,1), there are 2 obsevations, so a
number '2' will be displayed in the plot.
Is my narrative clear? Is there a way to make the plot
in R?

You can do the following (don't know it this is the most efficient way but
it works)

temp<-read.table("your file to read the data", header=T)
temp1<-table(temp)
plot(temp$x, temp$y, cex=0)
text(as.numeric(rownames(temp1)), as.numeric(colnames(temp1)), temp1)

See ?sunflowerplot for a graphic indication of 
the number of replications at each point.

Hi all,

This is nowhere near as elegant as Deepayan's solution, but I read the 
spec as plotting symbols except where there were overlays. You are 
welcome to improve the following...
