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. |
paletteName |
RColorBrewer palette name to use when
|
radius |
Radius (pixels) of monitor circles. |
opacity |
Opacity of monitor circles. |
maptype |
Optional name of leaflet ProviderTiles to use, e.g. |
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")
}
