AirSensor (version 1.0.8)

pas_staticMap: Static map of PurpleAir sensors

Description

Creates a static map of a pas object

Users can create a map using any numeric data column within the pas object:

"pm25" "temperature" "humidity" "pressure" "pm25_current" "pm25_10min" "pm25_30min" "pm25_1hr" "pm25_6hr" "pm25_1day" "pm25_1week" "pwfsl_closestDistance"

Available paletteName options include an "AQI" color palette, as well as a suite of sequential and diverging palettes from the RColorBrewer R package.

The sequential palette names are

"Blues" "BuGn" "BuPu" "GnBu" "Greens" "Greys" "Oranges" "OrRd" "PuBu" "PuBuGn" "PuRd" "Purples" "RdPu" "Reds" "YlGn" "YlGnBu" "YlOrBr" "YlOrRd"

The diverging palette names are

"BrBG" "PiYG" "PRGn" "PuOr" "RdBu" "RdGy" "RdYlBu" "RdYlGn" "Spectral"
