[R] as.dendrogram for DICE coefficient.

Hi R,



I was using 'as.dendrogram' with the DIST coefficient, where the smaller
values of the DIST coefficient, say that the objects are closer to each
other, while the larger values of the coefficient say that the objects
are far from each other.



But now, I have my coefficient as the DICE coefficient(in some sense
similar to correlation coefficient), where the larger coefficient value
indicates closer objects, while the small coefficient values indicate
farther objects. But, once I draw the dendrogram, the initial groupings
happens to the smaller DICE coefiicients and then to the larger, which
should not be the case, because, the objects with larger coefficients
are closer to each other than the smaller. How do I say the
as.dendrogram to group the objects for larger values of the DICE
coefficient?



Thanks,

Shubha
