If number is the number of points, I guess you can write 
plot(...., lwd=number)

Is there any function to show the points like this example of SPSS?

http://biostatistic.de/temp/reg.jpg

The point size should represent the number of data at this point.

plot with cex for the size and pch for solid points:
   xys=data.frame(x=c(0,0,1,2,2,3,3),y=c(0,1,1,1,2,2,3),s=c(4,1,2,1,1,1,2))

plot(xys$x,xys$y,cex=xys$s,pch=19)

or 'symbols', but you need to scale things a bit:

symbols(xys$x,xys$y,circles=xys$s/15,inches=F,bg="black")

Of course if your data is just (x,y) pairs and you want to work out the 
counts then that's another problem...

There are a couple of functions in CRAN packages I believe that will do
bubble plots.

You might want to do:

  RSiteSearch("Bubble Plot")

which should help.

A better option from a visualization perspective would be 

  ?sunflowerplot

Maybe, but I was told to search for bubbles. I will suggest the sunflowerplots.


Thank you very much
