pat_externalFit: Linear model fitting of PurpleAir and federal PWFSL time...

In MazamaScience/AirSensor: Process and Display Data from Air Quality Sensors

Linear model fitting of PurpleAir and federal PWFSL time series data

Description

Produces a linear model between data from PurpleAir and data from the closest PWFSL monitor.

A diagnostic plot is produced if 'showPlot = TRUE'.

Usage

pat_externalFit(
  pat = NULL,
  showPlot = TRUE,
  size = 1,
  pa_color = "purple",
  pwfsl_color = "black",
  alpha = 0.5,
  lr_shape = 15,
  lr_color = "black",
  lr_lwd = 1.5,
  lr_lcolor = "tomato",
  lr_lalpha = 0.45,
  ts_shape = 1,
  xylim = NULL,
  channel = "ab",
  replaceOutliers = TRUE,
  qc_algorithm = "hourly_AB_01",
  min_count = 20
)

Arguments

pat	PurpleAir Timeseries pat object.
showPlot	Logical specifying whether to generate a model fit plot.
size	Size of points.
pa_color	Color of hourly points.
pwfsl_color	Color of hourly points.
alpha	Opacity of points.
lr_shape	Symbol to use for linear model points.
lr_color	Color of linear model plot points.
lr_lwd	Width of linear regression line.
lr_lcolor	Color of linear regression line.
lr_lalpha	Opacity of linear regression line.
ts_shape	Symbol to use for time series points.
xylim	Vector of (lo,hi) limits used as limits on the correlation plot axes – useful for zooming in.
channel	Data channel to use for PM2.5 – one of "a", "b or "ab".
replaceOutliers	Logical specifying whether or not to replace outliers.
qc_algorithm	Named QC algorithm to apply to hourly aggregation stats.
min_count	Aggregation bins with fewer than 'min_count' measurements will be marked as 'NA'.

Value

A linear model, fitting the 'pat' PurpleAir readings to the closest PWFSL monitor readings.
