Hi, I am clustering objects using the agnes() function and the UPGMA clustering method (function = "average"). Everything works well, but apparently something is wrong with the dendrogram. For example:
x<-c(102,102.1,112.5,113,100.3,108.2,101.1,104,105.5,106.3) y<-c(110,111,110.2,112.1,119.5,122.1,102,112,112.5,115) xy<-cbind(x,y) library(cluster) UPGMA.orig<-agnes(x) plot(UPGMA.orig,which.plots=2,xlab="",main="",sub="") Look how the dendrogram has been drawn: all the OTUs should line up with 0.0 on the "distance" axis, but it is not the case in the dendrogram obtained here. Is it possible to obtain a traditional dendrogram? (I am using R 2.7.0 with Windows XP) Thanks and best wishes, Marcin ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
