[R] hierarhical cluster analysis of groups of vectors

[Anders Malmendal]

Thanks.
The vectors are produced by PLS-discriminant analysis between groups and 
the vectors within a group are simply different measurements of the same 
thing. What I need is a measure of how the different groups cluster 
(relative to each other). (I assume that I can do some averaging after 
applying dist, but I can not  find the information on how to do it.)
Best regards
Anders
