Pass info from D3 back to [R]

[TS404]

Could data be passed back from the visualisation to an object in [R]?

For example. on this simple shiny app I'd ideally like to be able to populate a list in [R] based on nodes that are clicked. Currently, I have to do it via a checkbox list and clicking the nodes just calls a basic 'alert("You clicked " + d.name);'.
