pat_multiPlot: Display multiple plots on one page

In AirSensor: Process and Display Data from Air Quality Sensors

Description

A plotting function that uses ggplot2 to display multiple ggplot objects in a single pane. Can either be passed individual ggplot objects OR a pat object and a plot type. Typical usage would be to supply pat and use the plottype argument to quickly display preformatted plots.

Available plottype options include:

• "all" – pm25_A, pm25_B, temperature, humidity

• "pm25_a" – PM2.5 from channel A only

• "pm25_b" – PM2.5 from channel B only

• "pm25" – PM2.5 from channels A and B in separate plots

• "pm25_over" – PM2.5 from channels A and B in the same plot

• "aux" – auxiliary data (temperature, humidity)

Usage

pat_multiPlot(
  pat = NULL,
  plottype = "all",
  sampleSize = 5000,
  columns = NULL,
  ylim = NULL,
  a_size = 1,
  a_shape = 15,
  a_color = rgb(0.9, 0.25, 0.2),
  b_size = 1,
  b_shape = 15,
  b_color = rgb(0.2, 0.25, 0.9),
  t_size = 1,
  t_shape = 15,
  t_color = "black",
  h_size = 1,
  h_shape = 15,
  h_color = "black",
  alpha = 0.5,
  timezone = NULL
)

pat_multiplot(
  pat = NULL,
  plottype = "all",
  sampleSize = 5000,
  columns = NULL,
  ylim = NULL,
  a_size = 1,
  a_shape = 15,
  a_color = rgb(0.9, 0.25, 0.2),
  b_size = 1,
  b_shape = 15,
  b_color = rgb(0.2, 0.25, 0.9),
  t_size = 1,
  t_shape = 15,
  t_color = "black",
  h_size = 1,
  h_shape = 15,
  h_color = "black",
  alpha = 0.5,
  timezone = NULL
)

Arguments

pat	PurpleAir Timeseries pat object.
plottype	Quick-reference plot types: "all", "aux", "pm25".
sampleSize	Either an integer or fraction to determine sample size.
columns	Number of columns in the plot layout. Use NULL for defaults.
ylim	Vector of (lo,hi) y-axis limits.
a_size	Size of pm25_A points.
a_shape	Symbol to use for pm25_A points.
a_color	Color of pm25_A points.
b_size	Size of pm25_B points.
b_shape	Symbol to use for pm25_B points.
b_color	Color of pm25_B points.
t_size	Size of temperature points.
t_shape	Symbol to use for temperature points.
t_color	Color of temperature points.
h_size	Size of humidity points.
h_shape	Symbol to use for humidity points.
h_color	Color of humidity points.
alpha	Opacity of points.
timezone	Olson timezone used for the time axis. (Defaults to pat local time.)

Value

A ggplot object.
