monitor_dailyBarplot: Create Daily Barplot

In PWFSLSmoke: Utilities for Working with Air Quality Monitoring Data

Description

Creates a bar plot showing daily average PM 2.5 values for a specific monitor in a ws_monitor object. Each bar is colored according to its AQI category.

This function is a wrapper around base::barplot and any arguments to that function may be used.

Each 'day' is the midnight-to-midnight period in the monitor local timezone. When tlim is used, it is converted to the monitor local timezone.

Usage

monitor_dailyBarplot(
  ws_monitor,
  monitorID = NULL,
  tlim = NULL,
  minHours = 18,
  gridPos = "",
  gridCol = "black",
  gridLwd = 0.5,
  gridLty = "solid",
  labels_x_nudge = 0,
  labels_y_nudge = 0,
  ...
)

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] or POSIXct)
minHours	minimum number of valid data hours required to calculate each daily average
gridPos	position of grid lines either 'over', 'under' (” for no grid lines)
gridCol	color of grid lines (see graphical parameter 'col')
gridLwd	line width of grid lines (see graphical parameter 'lwd')
gridLty	type of grid lines (see graphical parameter 'lty')
labels_x_nudge	nudge x labels to the left
labels_y_nudge	nudge y labels down
...	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)

N_M <- monitor_subset(Northwest_Megafires, tlim = c(20150715, 20150930))
main <- "Daily Average PM2.5 for Omak, WA"
monitor_dailyBarplot(N_M, monitorID = "530470013_01", main = main,
                         labels_x_nudge = 1)
addAQILegend(fill = rev(AQI$colors), pch = NULL)
