pulseMarkers: Make pulse-icon set
In leaflet.extras: Extra Functionality for 'leaflet' Package

Make pulse-icon set

Make Pulse Icon

An icon can be represented as a list of the form list(color, iconSize, ...). This function is vectorized over its arguments to create a list of icon data. Shorter argument values will be re-cycled. NULL values for these arguments will be ignored.

Add Pulse Markers

## S3 method for class 'leaflet_pulse_icon_set'
x[i]

makePulseIcon(color = "#ff0000", iconSize = 12, animate = TRUE,
  heartbeat = 1)

pulseIcons(color = "#ff0000", iconSize = 12, animate = TRUE,
  heartbeat = 1)

addPulseMarkers(map, lng = NULL, lat = NULL, layerId = NULL,
  group = NULL, icon = NULL, popup = NULL, popupOptions = NULL,
  label = NULL, labelOptions = NULL, options = leaflet::markerOptions(),
  clusterOptions = NULL, clusterId = NULL,
  data = leaflet::getMapData(map))

`...`	icons created from `makePulseIcon()`
`x`	icons
`i`	offset
`color`	Color of the icon
`iconSize`	Size of Icon in Pixels.
`animate`	To animate the icon or not, defaults to TRUE.
`heartbeat`	Interval between each pulse in seconds.
`map`	the map to add pulse Markers to.
`lng`	a numeric vector of longitudes, or a one-sided formula of the form `~x` where `x` is a variable in `data`; by default (if not explicitly provided), it will be automatically inferred from `data` by looking for a column named `lng`, `long`, or `longitude` (case-insensitively)
`lat`	a vector of latitudes or a formula (similar to the `lng` argument; the names `lat` and `latitude` are used when guessing the latitude column from `data`)
`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.
`icon`	the icon(s) for markers;
`popup`	a character vector of the HTML content for the popups (you are recommended to escape the text using `htmlEscape()` for security reasons)
`popupOptions`	options for popup
`label`	a character vector of the HTML content for the labels
`labelOptions`	A Vector of `labelOptions` to provide label options for each label. Default `NULL`
`options`	a list of extra options for tile layers, popups, paths (circles, rectangles, polygons, ...), or other map elements
`clusterOptions`	if not `NULL`, markers will be clustered using Leaflet.markercluster; you can use `markerClusterOptions()` to specify marker cluster options
`clusterId`	the id for the marker cluster layer
`data`	the data object from which the argument values are derived; by default, it is the `data` object provided to `leaflet()` initially, but can be overridden

  red = makePulseIcon(color = "#ff0000"),
