Perhaps the post at http://www.codesofmylife.com/2012/06/07/plotting-pca-results-with-ggplot2/ would help? (as would googling "biplot in ggplot2", which is how I found it...) Incidentally, if you want base graphics biplots with points and colour coding, you'd need to modify the biplot code a bit or roll your own.
