Make weather-icon set

Description

Make weather-icon set

Make Weather Icon

An icon can be represented as a list of the form list(icon, markerColor, ...). 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 Weather Markers

Usage

weatherIconList(...)

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

makeWeatherIcon(icon, markerColor = "red", iconColor = "white",
  extraClasses = NULL)

weatherIcons(icon, markerColor = "red", iconColor = "white",
  extraClasses = NULL)

addWeatherMarkers(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))

Arguments

`...`	icons created from `makeWeatherIcon()`
`x`	icons
`i`	offset
`icon`	the weather icon name w/o the "wi-" prefix. For a full list see https://erikflowers.github.io/weather-icons/
`markerColor`	color of the marker
`iconColor`	color of the weather icon
`extraClasses`	Character vector of extra classes.
`map`	the map to add weather 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.
`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

Examples

iconSet = weatherIconList(
  hurricane = makeWeatherIcon(icon = "hurricane"),
  tornado = makeWeatherIcon(icon = "tornado")
)

iconSet[c("hurricane", "tornado")]
leaflet() %>%
  addTiles() %>%
  addWeatherMarkers(
    lng = -118.456554, lat = 34.078039,
    label = "This is a label",
    icon = makeWeatherIcon(
      icon = "hot",
      iconColor = "#ffffff77",
      markerColor = "blue"
    )
  )
