Pass info from D3 back to [R] #272

Closed TS404 closed 4 years ago

TS404 commented 4 years ago

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);'.

(Also asked at r2d3-I79)

You'll need to look into Shiny Reactivity, which is not part of this package.

Here is one example of using Shiny Reactivity with a networkD3 plot.

Also in general, please provide a minimal reproducible example when asking for support.

Also FYI, networkD3 does not use r2d3, so they likely will not help you over there.

Ah, thank you! That makes sense. Doubly thank you for the MRD link. I'll aim to do so in future.
