I got a hint of package ade4 and function dudi.pca. Something like this, though I can't immediately interpret those dudi.pca-pictures. I originally saw this as a more general idea, which can, if wanted, be applied with statistical methods too. If you do multidimensional scaling, you can see, how "near" all components are each other, but you can't see the connections or directions. If you have a correlation matrix, you can't see the connections graphically.
