Dear R-users, I was wondering if it possible to produce clustergrams in R (further information about clustergrams in the references below). Schonlau, M. Visualizing Hierarchical and Non-Hierarchical Cluster Analyses with Clustergrams. Computational Statistics: 2004; 19(1): 95-111. Schonlau M. "The clustergram: a graph for visualizing hierarchical and non-hierarchical cluster analyses." The Stata Journal, 2002; 2 (4):391-402. Any help would be greatly appreciated. Best regards, Tormod B?e
