pas_leaflet: Leaflet interactive map of PurpleAir sensors

In MazamaScience/AirSensor2: Process and Display Data from Air Quality Sensors

Leaflet interactive map of PurpleAir sensors

Description

This function creates interactive maps that will be displayed in RStudio's 'Viewer' tab.

When parameter is not specified, a simple map is displayed. When the user clicks on a location, site metadata is displayed.

When parameter is specified, it is assumed that a pas object has been created with measured parameters for a particular moment in time.

For a pas object that includes measurements, typical usage would be to use the parameter argument to display pm25 values from one of:

• "pm2.5_10minute"

• "pm2.5_30minute"

• "pm2.5_60minute"

• "pm2.5_6hour"

• "pm2.5_24hour"

• "pm2.5_1week"

Usage

pas_leaflet(
  pas = NULL,
  parameter = NULL,
  paletteName = NULL,
  radius = 10,
  opacity = 0.8,
  maptype = "terrain"
)

Arguments

pas	PurpleAir Synoptic pas object.
parameter	Optional parameter used to color locations, e.g. pm25_1hr.
paletteName	RColorBrewer palette name to use when parameter is something other than: "pm2.5_~" "humidity "temperature
radius	Radius (pixels) of monitor circles.
opacity	Opacity of monitor circles.
maptype	Optional name of leaflet ProviderTiles to use, e.g. terrain.

Details

The maptype argument is mapped onto leaflet "ProviderTile" names. Current mappings include:

"roadmap"

– "OpenStreetMap"

"satellite"

– "Esri.WorldImagery"

"terrain"

– "Esri.WorldTopoMap"

"toner"

– "Stamen.Toner"

If a character string not listed above is provided, it will be used as the underlying map tile if available. See https://leaflet-extras.github.io/leaflet-providers/ for a list of "provider tiles" to use as the background map.

Value

A leaflet "plot" object which, if not assigned, is rendered in Rstudio's 'Viewer' tab.

Note

The paletteName parameter can take the name of an RColorBrewer paeltte, e.g. "BuPu" or "Greens".

Examples

library(AirSensor2)

if ( interactive() ) {
  pas_leaflet(example_pas_pm25, parameter = "pm2.5_60minute")

  pas_leaflet(example_pas_pm25, parameter = "temperature")

  pas_leaflet(example_pas_pm25, parameter = "humidity")
}
