monitor_staticmap: Create a static map of ws_monitor object

In PWFSLSmoke: Utilities for Working with Air Quality Monitoring Data

Description

Plots a map showing ws_monitor locations and values.

See staticmap_getRasterBrick for a list of available maptype options.

If centerLon, centerMap or zoom are not specified, appropriate values will be calcualted using data from the ws_monitor$meta dataframe.

Usage

monitor_staticmap(
  ws_monitor,
  slice = get("max"),
  breaks = AQI$breaks_24,
  colors = AQI$colors,
  width = 640,
  height = 640,
  centerLon = NULL,
  centerLat = NULL,
  zoom = NULL,
  maptype = "terrain",
  grayscale = FALSE,
  rasterBrick = NULL,
  cex = par("cex") * 2,
  pch = 16,
  ...
)

Arguments

ws_monitor	ws_monitor object
slice	either a time index or a function used to collapse the time axis – defautls to get('max')
breaks	set of breaks used to assign colors
colors	a set of colors for different levels of air quality data determined by breaks
width	width of image, in pixels
height	height of image, in pixels
centerLon	map center longitude
centerLat	map center latitude
zoom	map zoom level
maptype	map type
grayscale	logical, if TRUE the colored map tile is rendered into a black & white image
rasterBrick	optional RGB rasterBrick object returned from staticmap_get~Brick)
cex	character expansion for points
pch	plotting character for points
...	arguments passed on to staticmap_plotRasterBrick() (e.g. destfile, cex, pch, etc.)

Value

A plot with a basemap and colored dots for each monitor.
