Amna, You have posted this question to the list several times now over the past few weeks.
Several of us have recommended hclust() as a starting point. However, your question about the optimal number of clusters to choose is not an R question. I recommend that you tackle the literature on this topic. If you don't have access to texts and journals then try a statistics listserv. But, even a Google search on cluster analysis will provide you plenty of direction. Best wishes. Sincerely, Jeff Miller **************************************** Jeffrey M.
