...e a multi-color silhouette plot (each cluster a different color) from clusters created by trimkmeans. This works straighforwardly on an object created from pam however my colors are interwoven when I try the same approach on clusters from trimkmeans. I also tried sorting the silhouette object using sortSilhouette which did not solve the problem. If anyone has a suggestion, please let me know. I'm using R 2.4.0 on an XP based PC. Thanks very much, Joe Retzer [[alternative HTML version deleted]]

...ster, and the cluster that should be black is actually yellow? plot(si3, nmax = 80, cex.names = 0.5, col=c("red","blue","yellow","black","green")) # 3. Check sorting by writing out sorted results to a file, then plotting from the file si3.sorted<-sortSilhouette(si3) write.table(si3.sorted,"/...myPath.../si3.sorted.txt",sep="\t") Inspecting the si3.sorted.txt file, cluster numbers are ordered as expected (1's then 2's then...), and sil_width's within each cluster appear correctly sorted (descending). Given this, if I load...

Dear R users, I am mailing you about the graphical output of silhouette (cluster package) From the example of silhouette in help(silhouette): > ar <- agnes(ruspini) > si3 <- silhouette(cutree(ar, k = 5), # k = 4 gave the same as pam() above + daisy(ruspini)) > plot(si3, nmax = 80, cex.names = 0.5) from which one may conclude that group 1 is composed by
