Hi,
Another newbie question. Once I have generated a PCA model using the princomp
command how can i use it to display a new dataset ?
Thanks for your help

It has a predict method, and ?predict points you to it.

predict() is the usual way to apply a model to new data: see `An 
Introduction to R' or any good book on S/R.
