Dear list, I really appreciate previous suggestion about self organizing map. I tried to perform SOM analyses with kohonen, som and class packages, but it's not clear to me if these packages are complete to: 1) cluster neurons according to their similarities (U-matrix); 2) assign to SOM neurons variables names; 3) define the importance of each variable, like in figures 2,3 and 5 of http://dx.doi.org/10.1016/j.ecolmodel.2005.10.044 for example. Thanks so much! Sincerely, Gianandrea -- View this message in context: http://www.nabble.com/Self-Organizing-Map-tp22778862p22778862.html Sent from the R help mailing list archive at Nabble.com.
