plot.TwoRegression: Create summary plots for TwoRegression objects

In TwoRegression: Develop and Apply Two-Regression Algorithms

Create summary plots for TwoRegression objects

Description

Four plots are generated: a threshold plot for both cut-points, and a model plot for both regression models

Usage

## S3 method for class 'TwoRegression'
plot(
  x = NULL,
  object = NULL,
  sed_cp_activities,
  sed_activities,
  sed_cpVar = NULL,
  activity_var,
  met_var,
  walkrun_activities,
  walkrun_cpVar,
  x_sed = NULL,
  y_sed = NULL,
  x_walkrun = NULL,
  y_walkrun = NULL,
  print = TRUE,
  ...
)

Arguments

x	passed from generic function but not used in the method
object	the TwoRegression object
sed_cp_activities	Character vector. Activities to be included in the process of forming the sedentary classifier
sed_activities	Character vector. Actual sedentary activities
sed_cpVar	character scalar. The name of the variable on which the cut-point is based
activity_var	Character scalar. Name of the variable defining which activity is being performed
met_var	character scalar. The name of the variable containing energy expenditure values, in metabolic equivalents
walkrun_activities	Character vector. Actual ambulatory activities
walkrun_cpVar	character scalar giving the name of the variable on which the walk/run cut-point is based
x_sed	numeric scalar giving x coordinate for label placement in sedentary cut-point plot
y_sed	numeric scalar giving y coordinate for label placement in sedentary cut-point plot
x_walkrun	numeric scalar giving x coordinate for label placement in walk/run cut-point plot
y_walkrun	numeric scalar giving y coordinate for label placement in walk/run cut-point plot
print	logical. Should the plot be arranged in a grid? If false, the panels will be returned in a list of gg/ggplot objects.
...	further arguments passed to plotting calls

Value

A two-by-two grid of summary plots
