[R] Can a hyperlink be placed, thorugh R programming, on a graph?

[Aldi Kraja]

Hi,
If I use 

x<-1:10
 y<-rnorm(10,0,1)
### pdf(file="c:\\aldi\\test.pdf")
 plot(x,y)
 segments(x,y,x+2,y+2)
 segments(x,y,x+0.5,y+0.5,col=3)
### dev.off()
### q()

Is there a way that I can imbed in the graph plot for each point defined 
by x to x+0.5 and y to y+0.5 (and colored in green) a different hyperlink?

For example point one (together with the green tail) will have the 
hyperlink: www.r-project.org; point 2 with the link www.google.com; 
point 3 with the link www.yahoo.com etc.

So in general, can the graph be manupulated within R?

TIA,

Aldi
