Avoiding Biplot Labels Overllaping

Dear Rodrigo

The best thing to do is to label manually the points in the biplot. To do so
you have to use the following comand:

text(location, "text to place")

*location* can be an x,y coordinate. Alternatively, the text can be placed
interactively via mouse by specifying location as *locator(1)*. See more
detailed description at http://www.statmethods.net/advgraphs/axes.html.
