Hello everybody, I need to know how often every element in an hierarchical cluster was "branched" - just imagine a watering pot on the top of the hierarchical tree -> the leafs should get water according to the number of branches that lie before them. For example: a <- list() # initialize empty object a$merge <- matrix(c(-1, -2, -3, -4, 1, 2, -5,-6, 3,4), nc=2, byrow=TRUE ) a$height <- c(1, 2, 3,4,5) a$order <- c(1,2,3,4,5,6) a$labels <- 1:6 class(a) <- "hclust" plot(a) The leaf "1" has was branched three times -> it would get 1/2^3 = 0.125 of the "total water". Same for leaf 2.Leafs 3 and 4 would each get the same (0.125). Leaf 5 and 6 would get 0.25 -> Adding up to 1. Does anybody have a clue? Thanks a lot in advance! Lui
