R:plot and dots

Here is an example :

   x <- rnorm(20)
   y <- rnorm(20)
   plot(x, y, type="n")
   text(x, y, labels=as.character(1:20))

Also look into help(identify) if you want to point out specific points.

hi all

a very simple question.

i have plot(x,y)

but i would like to add in on the plot the observation number associated
with each point.

how can this be done?
