Hi,

I repeatedly obtained meaningless results from the function 'cutree' 
in the 'mva' package, when the argument 'h' was greater or equal to 
the maximum height occuring: 

> library('mva')
> y
     [,1] [,2] [,3] [,4]
[1,]    0    1   -1    1
[2,]    0   -1    1    0
[3,]    0   -1    1    1
[4,]   -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))
> cluster
[1] 1108612352          1 1074517880          1

Best regards,

Anja
