# Heat map of the dissimilarity matrix ordered with the dendrogram
heatmap(
as.matrix(spe.ch),
Rowv = dend,
symm = TRUE,
margin = c(3, 3)
)
Hint Note that the hclust object has been converted to an object of class
dendrogram. This allows many advanced graphical manipulations of tree-like
structures. See the documentation file of the as.dendrogram() function,
where examples are given.
