Thank you

Here is an executable version of Anja's example:
library('mva')
y <-
rbind(c( 0, 1, -1, 1),
c( 0, -1, 1, 0),
c( 0, -1, 1, 1),
c(-1, -2, 1, 0))
d <- dist(y, method="manhattan")
hc <- hclust(d, method = "complete")
hc$height
## [1] 1 3 7
( cluster <- cutree(hc, h=max(hc$height)))
## Anja got
## [1] 1108612352 1 1074517880 1
## Martin: I get
## [1] 0 0 0 0
even though I don't get random results, it's still wrong.
I'll look at a fix.
