[R] enhanced multidimensional scaling?

[Karen Kotschy]

Dear R list

Would anyone be able to tell me whether it is possible to do "enhanced 
multidimensional scaling" (enhanced MDS) in R? In other words, something that 
goes beyond "cmdscale" by iteratively improving the fit between observed 
dissimilarities and inter-object distances, using the KYST algorithm 
(Kruskal, 1964).

I have found several implementations of non-metric MDS in various packages but 
nothing like what I have described above.

Thanks in advance
