pas_leaflet: Leaflet interactive map of PurpleAir sensors

In AirSensor: Process and Display Data from Air Quality Sensors

Description

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

Typical usage would be to use the parameter argument to display pm25 values from one of:

• "pm25_current"

• "pm25_10min"

• "pm25_30min"

• "pm25_1hr"

• "pm25_6hr"

• "pm25_1day"

• "pm25_1week"

Auxiliary parameter arguments can be used to display various Purple Air sensor data. Currently supported parameter arguments include:

• "humidity"

• "pressure"

• "temperature"

• "pwfsl_closestDistance"

Usage

pas_leaflet(
  pas = NULL,
  parameter = "pm25_1hr",
  paletteName = NULL,
  radius = 10,
  opacity = 0.8,
  maptype = "terrain",
  outsideOnly = TRUE
)

Arguments

pas	PurpleAir Synoptic pas object.
parameter	Value to plot, e.g. pm25_1hr.
paletteName	Predefined color palette name. Can be of the following: "AQI" "humidity "temperature "distance"
radius	Radius (pixels) of monitor circles.
opacity	Opacity of monitor circles.
maptype	Optional name of leaflet ProviderTiles to use, e.g. terrain.
outsideOnly	Logical specifying subsetting for monitors marked as 'outside'.

Details

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

1. "roadmap" – "OpenStreetMap"

2. "satellite" – "Esri.WorldImagery"

3. "terrain" – "Esri.WorldTopoMap"

4. "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(AirSensor)
setArchiveBaseUrl("http://data.mazamascience.com/PurpleAir/v1")

# California
ca <-
  pas_load() %>%
  pas_filter(stateCode == 'CA')

if ( interactive() ) {
  pas_leaflet(ca, parameter = "pm25_1hr")

  pas_leaflet(ca, parameter = "temperature")

  pas_leaflet(ca, parameter = "humidity")

  pas_leaflet(ca, parameter = "pwfsl_closestDistance", maptype = "satellite")
}
