Dissimilarity matrix and number clusters determination
Hi,
I already have a dissimilarity matrix and I am submitting the results to
the elbow.obj method to get an optimal number of clusters. Am I reading

, stand = TRUE
, type = list(symm = 1))
}
dist.obj <- dist(cluster1)
hclust.obj <- hclust(dist.obj)
css.obj <- css.hclust(dist.obj,hclust.obj)
elbow.obj <- elbo...
