Adding node labels to dendrogram plot in dendextend

Question

I have a dendrogram with leaf and node labels (class=phylo, read in using read.tree). After converting this to dendrogram class the node labels are not there anymore. However, I would like to plot the dendrogram by showing labels on top of some nodes (ie in the form NODE_1 etc. on top of the selected clusters).

Does anyone know how can I get node labels to dendrogram class and add them to the plot? Something similar like this, but instead of numbers there are id-s or labels and only some selection of nodes have the labels.

I would convert your dendrogram to phylo class with as.phylo . When plotting you can do plot(phylo, show.node.label = TRUE) .
