Shiny interactive graph and dygraphs

[Shi Yu]

Is there anyway to combine shiny interactive plot options wiht dygraphs plot? Say, using 

plotOutput("plot1", click = "plot_click", dblclick = "plot_dblclick", hover = "plot_hover", brush = "plot_brush" )

for

dygraphOutput("plot1")

Look at the shiny dygraphs demo, it is easy to see how dygraph_date_window is returned to shinyServer, but it is not intuitive to me how I can obtain other information, such nearest data points using "plot_click" or "plot_hover" with dygrpha. 

Thanks,
