The collapsibleTree library allows to build interactive collapsible Reingold-Tilford tree diagrams. Click on a node to see the underlying sub-nodes. The required input is a nested data frame. If your hierarchy is presented as an edge list, the graph #338 shows how to make the transformation using the data.tree library.

Visit the GitHub page of collapsibleTree to see all the possible customization.
