Dear helpers I'm sorry to insist but I still think there is something wrong with the function kmeans. For instance, let's try the same small example: > dados<-matrix(c(-1,0,2,2.5,7,9,0,3,0,6,1,4),6,2)
I will choose observations 3 and 4 for initial centers and just one iteration. The results are > A<-kmeans(dados,dados[c(3,4),],1) > A $cluster [1] 1 1 1 1 2 2 $centers [,1] [,2] 1 0.875 2.75 2 8.000 2.50 $withinss [1] 38.9375 6.5000 $size [1] 4 2 If I do it by hand, after one iteration, the results are $cluster [1] 1 2 1 2 1 2 So I think that something is wrong with the function kmeans; probably the initial centers given by the user are not being taken into account. ______________________________________________ [EMAIL PROTECTED] mailing list https://www.stat.math.ethz.ch/mailman/listinfo/r-help
