monitor_hourlyBarplot: Create Hourly Barplot

In PWFSLSmoke: Utilities for Working with Air Quality Monitoring Data

Description

Creates a bar plot showing hourly PM 2.5 values for a specific monitor in a ws_monitor object. Colors are assigned to one of the following styles:

• AQI – hourly values colored with AQI colors using AQI 24-hour breaks

• brownScaleAQI – hourly values colored with brownscale colors using AQI 24-hour breaks

• grayScaleAQI – hourly values colored grayscale colors using AQI 24-hour breaks

Usage

monitor_hourlyBarplot(
  ws_monitor,
  monitorID = NULL,
  tlim = NULL,
  localTime = TRUE,
  style = "AQI",
  shadedNight = TRUE,
  gridPos = "",
  gridCol = "black",
  gridLwd = 0.5,
  gridLty = "solid",
  labels_x_nudge = 0,
  labels_y_nudge = 0,
  dayCol = "black",
  dayLwd = 2,
  dayLty = "solid",
  hourCol = "black",
  hourLwd = 1,
  hourLty = "solid",
  hourInterval = 6,
  ...
)

Arguments

ws_monitor	ws_monitor object
monitorID	monitor ID for a specific monitor in ws_monitor (optional if ws_monitor only has one monitor)
tlim	optional vector with start and end times (integer or character representing YYYYMMDD[HH])
localTime	logical specifying whether tlim is in local time or UTC
style	named style specification ('AirFire')
shadedNight	add nighttime shading
gridPos	position of grid lines either 'over', 'under' ("" for no grid lines)
gridCol	grid color
gridLwd	grid line width
gridLty	grid line type
labels_x_nudge	nudge x labels to the left
labels_y_nudge	nudge y labels down
dayCol	day boundary color
dayLwd	day boundary line width (set to 0 to omit day lines)
dayLty	day boundary type
hourCol	hour boundary color
hourLwd	hour boundary line width (set to 0 to omit hour lines)
hourLty	hour boundary type
hourInterval	interval for hour boundary lines
...	additional arguments to be passed to barplot()

Details

The labels_x_nudge and labels_y_nudge can be used to tweak the date labeling. Units used are the same as those in the plot.

Examples

library(PWFSLSmoke)

C_V <- monitor_subset(Carmel_Valley, tlim = c(2016080800,2016081023),
                      timezone = "America/Los_Angeles")

monitor_hourlyBarplot(C_V, main = "1-Hourly Average PM2.5",
                      labels_x_nudge = 1, labels_y_nudge = 0)
