[R] Numbers as Points in Graphs

Actually Ted,

Mark's code worked perfectly although I am not really sure why. I am fairly
confused by Ted'scode anyways, even though I'm sure it is right. Here is
what it amounted to for my case:

plot(Length ~ Width, data=infiltration1, col="blue", xlab = "Width (cm)",
ylab = "Length (m)", xlim=c(0,200), ylim=c(0,30), type="n")
text(infiltration1$Width, infiltration1$Length, infiltration1$Bag.Number)

I don't really understand why I am specifying the x.y coordinates twice.
Also is it always the third component of the text argument that specifies
the point "label"? Anyways, if anyone is inclined I love a little
explanation of this. Otherwise, thanks for the help.
