Add Velocity Animation

Description

Add velocity animated data to leaflet. Based on the leaflet-velocity plugin

Usage

addVelocity(
  map,
  layerId = NULL,
  group = NULL,
  content = NULL,
  options = velocityOptions()
)

Arguments

map	a map widget object created from leaflet()
layerId	the layer id
group	the name of the group the newly created layers should belong to (for clearGroup and addLayersControl purposes).

Any number of layers and even different types of layers (e.g. markers and polygons) can share the same group name.
content	the path or URL to a JSON file representing the velocity data or a data.frame which can be transformed to such a JSON file. Please see the demo files for some example data.
options	List of further options. See velocityOptions
