pat_scatterPlotMatrix: Draw a matrix of PurpleAir Timeseries data scatter plots

In AirSensor: Process and Display Data from Air Quality Sensors

Description

Creates a multi-panel scatterPlot comparing all variables in the pat object. If any variables have no valid data, they are omitted from the plot.

The list of available parameters include:

• datetime – measurement time

• pm25_A – A channel PM2.5 (ug/m3)

• pm25_B – B channel PM2.5 (ug/m3)

• temperature – temperature (F)

• humidity – humidity (%)

Usage

pat_scatterPlotMatrix(
  pat = NULL,
  parameters = c("datetime", "pm25_A", "pm25_B", "temperature", "humidity"),
  sampleSize = 5000,
  sampleFraction = NULL,
  size = 0.5,
  shape = 15,
  color = "black",
  alpha = 0.25
)

Arguments

pat	PurpleAir Timeseries pat object.
parameters	Vector of parameters to include.
sampleSize	Integer to determine sample size.
sampleFraction	Fractional sample size.
size	Size of points.
shape	Symbol to use for points.
color	Color of points.
alpha	Opacity of points.

Value

Multi-panel ggplot comparing all parameters.

Examples

library(AirSensor)

pat <- 
  example_pat %>% 
  pat_filterDate(20180811,20180818)
  
# NOTE:  Warnings are generated when the pat contains NA values
pat_scatterPlotMatrix(pat, sampleSize = 1000)
