I would like to adjust the x-axis in a dendrogram where all the labels are seen, for large data sets. As example, I use iris data here:
> iris.data=subset(iris,select=-Species)
> d <- dist(iris.data, method="euclidean")
> hc <- hclust(d, "ward")
> plot(hc, hang=-1, main="Dendrogram of Ward's Method", label=iris$Species)
After the plot function is used, the dendrogram will be like this:
So, how I'm going to adjust the x-axis so then all the species are all clear seen.
