addVelocity: 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). Human-friendly group names are permitted--they need not be short, identifier-style names. 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

Value
