Re: Auto point numbering with plot(x,y)

[Alan Zaslavsky <zaslavsk@hcp.med.harvard.edu>]

You can do something like

plot(x,y,type="n")
text(x,y,paste(1:number.of.rows))

if you want to use the row number as plotting labels.  If you want the 
points with adjacent labels then something more like
plot(x,y)
text(x+offset.x,y+offset.y,paste(1:number.of.rows))

will plot the point with the number label at some relative location you 
choose.
