hierarhical cluster analysis of groups of vectors
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. (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

It seems that you have already groups defined. Discriminant analysis would probably be more appropriate for what you want. Best regards, Rafael Duarte Anders Malmendal wrote:
I want to do hierarchical cluster analysis to compare 10 groups of vectors with five vectors in each group (i.e. I want to make a dendogram showing the clustering of the different groups). I've looked into using dist and hclust, but cannot see how to compare the different groups instead of the individual vectors. I am thankful for any help. Anders
