I am currently using the dendextend R package to export the data from an R dendrogram. I am specifically looking to extract the coordinates of each of the nodes in a dendrogram and also the start and stop position of each of the branches.
Getting the coordinates of the nodes seem to be fairly simple by using the dentextend::get_nodes_xy() function. However, I am not able to find any function that outputs the start and stop position of each of the branches in the dendrogram. Alternatively, if for each of the derived nodes (non-leaf nodes), if I could get the child nodes, I could calculate the start/stop position of the branches on my own.
In principle, a command like dend %>% unclass %>% str will print out the dendrogram, but this format is too cumbersome to parse especially for dendrograms with a very large number of nodes. So, I was wondering is there any way to get information about the child nodes for every node (not just leaves) in the dendrogram. It seems only the leaves have a label and non-leaf nodes do not have labels.
Looking for a function that prints start/stop position of branches of a dendrogram, or at least outputs the child nodes for every node in the dendrogram.
