[R] labelling plots with ancillary data in data.frame

Hi Wesley,

You can use the text() function to add text to an existing plot.   See  
?text.

I would now like to label my points using data stored in the data.frame used for the regression analysis. For example each of my data points is made up of a field measured forest volume value and a remotely sensed vegetation estimate (NDVI). Each point is an enumeration plot and I would like to label each the points in the xy-scatterplot with their respective plot numbers. Is this possible in R, if so how do I go about doing it?
