Create Hourly Barplot

Source: R/monitor_hourlyBarplot.R

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

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)
