For use focus() method in a shiny app. For full documentation, have a look at visDocumentation.
visFocus(
graph,
id,
scale = 2,
offset = list(x = 0, y = 0),
locked = TRUE,
animation = list(duration = 1500, easingFunction = "easeInOutQuad")
)
: a visNetworkProxy
object
: a node id
: Optional. Number. The scale is the target zoomlevel. Default value is 2.0.
: Optional. List. The offset (in DOM units) is how many pixels from the center the view is focussed. Default value is list(x = 0, y = 0).
: Optional. Boolean. Locked denotes whether or not the view remains locked to the node once the zoom-in animation is finished. Default value is true.
: Optional. List. For animation you can define the duration (in milliseconds) and easing function manually. Available are: linear, easeInQuad, easeOutQuad, easeInOutQuad, easeInCubic, easeOutCubic, easeInOutCubic, easeInQuart, easeOutQuart, easeInOutQuart, easeInQuint, easeOutQuint, easeInOutQuint. Default to list(duration = 1500, easingFunction = "easeInOutQuad")
