Short answer:  Try using "predict" instead of "predict.ssr".  I think
you're meant to quietly use the predict and plot methods provided, and not
mention their inner names.

Long answer:
Namespaces.  This means that a method for an object isn't visible to R as
a whole.  This avoids conflics should another package pick the same names.

Does this work?
