Dear all, I am a beginner in R and I am trying to organize my dendrogram in a better order to vizualize our data better. I am joining months based on the occurrence of spawning of species and would like the plot in order of months: Nov-Dec, Jan-Feb-Mar and then Apr-May-Jun Jul-Aug Sept-Oct Is that possible? K?tia. setwd("I:/UFS/Bolsas/Isaac") data<-read.table("desmest16fev14.txt",header=T) data rownames(data) <-data[,1] data <-data[,-1] d <- vegdist(data, method = "bray") d clust.res<-hclust(d,method="average") plot(clust.res,hang=-1,ylab="Bray Curtis",xlab="M?s") -------------- next part -------------- An embedded and charset-unspecified text was scrubbed...
