Competently with R Shiny - Client for communication with the server

Question

I would like to use plotly in a brilliant application, but I need information on plot interaction in R. Is there any way to make it intricate to send information / coordinates from hover, brush, etc. back to R

There is an earlier question - Can I return information such as: “location of the hover” and “Location of the brush”. or “click location,” but this API seems useful for client-side interaction. I have the feeling that being onInputChangebrilliant can help me achieve this, but I probably need to do some javascript encoding, which I'm not very good at (simple examples of this are also welcome). If there is a pure R + Shiny approach, that would be the best.
