I am having trouble changing the size of labels when plotting a dendrogram created from hclust, I want to do it this way so I can use the 'horiz=TRUE' option in a dendrogram plot and rotate my chart. Can anyone help either to tell my how to rotate a plot of an hclust object or to change the size of my labels in a dendrogram plot ## CODE THAT WORKS ##x<- dataframe of observations distance <- dist(t(x)) clust <- hclust(distance, method = "ward") plot(clust,cex=0.6) ##CODE THAT DOESN'T CHANGE THE SIZE OF DATA LABELS distance <- dist(t(x)) clust <- hclust(distance, method = "ward") dend=as.dendrogram(clust,hang=-1) plot(dend, cex=0.6,edgePar = list(lty=1, col=c("black","darkgrey")), edge.root=FALSE,horiz=TRUE) Regards, Tom Joy [[alternative HTML version deleted]]
