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.
