R help - May 2004 - PCA filtering

Hi,

Is there a function under R that does principal component analysis and then
use the selected eignevectors to filter the data and transform back to the
original coordinates?
If there isn't, can someone guide as to how to do this approach.

Much appreciated.

Does the "predict" function do what you want?
