Is a library available for R that includes algorithms for something called "archetypal analysis," a method similar to principal components analysis that is designed to find "archetypes" or "pure types" from multidimensional data. I have contacted one of the authors who has written about archetypal analysis but thought I'd check here also. Thanks.
