Update a ggWebGL Timeline from Shiny — updateGgWebGLTimeline • ggWebGL

Send a timeline update message to a rendered ggWebGL widget. The browser applies the update to the widget identified by outputId and emits the updated state back as input$<outputId>_timeline.

  index = NULL,
  playing = NULL,
  speed = NULL,
  loop = NULL
)
