Hi @sgratzl ,

Thank you for your answer. Yes, I used clicked$names to fetch the names but I don't know how to get the intersection parts back. Will it come back from the upset.js instance or somewhere?

[sgratzl]

The example consists of two parts:

upsetjs_r/r_package/shiny/events.R

Lines 41 to 47 in 872c5df

	output$hovered <- renderText({
	# hover event: <id>_hover -> list(name="NAME" or NULL, elems=c(...))
	input$upsetjs1_hover$name
	})
	output$hoveredElements <- renderText({
	as.numeric(input$upsetjs1_hover$elems)
	})

the first one is about the selected intersection name, the other about the selected elements. I don't understand what else you are looking for
