Dear Tom, I suggest you look at MASS (Modern Applied Statistics With S), by Venables & Ripley. These issues are explained there (someone borrowed my copy, so I can't tell you the chapter, pages, etc). You might also want to take a look in a multivariate stats. book (e.g., Krzanowski explains these issues very well) for general differences between PCA and factor analysis.
