Ok,
Here is a simple solution:
One can apply the text step (within a loop) for any other points and the
hyperlinks are functional in the pdf format, and not viewable unless the
mouse is over the link.
If you have a better solution, let me know.
x<-1:10
y<-rnorm(10,0,1)
pdf(file="c:\\aldi\\test.pdf")
plot(x,y)
segments(x,y,x+2,y+2)
text(x[3],y[3],c("http://www.r-project.org"),cex=0.1,col="white")
segments(x,y,x+0.5,y+0.5,col=3)
dev.off()
Thanks,
Aldi
