The usual way would be to get the source code for the function you are trying to change (or, fast way, with getAnywhere(pca)), copy it to an editor, and make the changes. However, better always rename it before using, e.g. pcaKaren <- function.... If the code you are trying to change is not directly called, but indirectly, things are more complicated. In most cases, it's easiest to get the whole package, put it into a different namespace, and make the changes. Easiest does not mean not easy, though.
