hoverOpts

From shiny v0.12.2 by Winston Chang

This generates an object representing hovering options, to be passed as the hover argument of imageOutput or plotOutput.

hoverOpts(id = NULL, delay = 300, delayType = c("debounce", "throttle"),
  clip = TRUE, nullOutside = TRUE)

id: Input value name. For example, if the value is "plot_hover", then the hover coordinates will be available as input$plot_hover.
delay: How long to delay (in milliseconds) when debouncing or throttling, before sending the mouse location to the server.
delayType: The type of algorithm for limiting the number of hover events. Use "throttle" to limit the number of hover events to one every delay milliseconds. Use "debounce" to suspend events while the cursor is moving, and wait
clip: Should the hover area be clipped to the plotting area? If FALSE, then the server will receive hover events even when the mouse is outside the plotting area, as long as it is still inside the image.
nullOutside: If TRUE (the default), the value will be set to NULL when the mouse exits the plotting area. If FALSE, the value will stop changing when the cursor exits the plotting area.
