Plot Regression Line — plotRegressionLine • EASI

Provides a plot of the regression line and its intervals.

Usage

# S3 method for default
plotRegression(frame, y=NULL, line=TRUE, value=NULL, range=NULL, interval="both", conf.level=.95, main=NULL, xlim=NULL, ylim=NULL, points=TRUE, cross=FALSE, col="black", values=TRUE, digits=3, add=FALSE)

# S3 method for wss
plotRegression(DescStats, CorrStats, y=NULL, line=TRUE, value=NULL, range=NULL, interval="both", conf.level=.95, main=NULL, xlim=NULL, ylim=NULL, cross=FALSE, col="black", values=TRUE, digits=3, add=FALSE)

Arguments

frame: a set of (non-empty) numeric vectors of data values
DescStats: a matrix/frame of descriptive/summary statistics
CorrStats: a matrix/frame of correlations for the data set
y: the name of the criterion
line: whether the regression line should be displayed
value: a specific regression value to display
range: the range of confidence and prediction intervals to display
interval: the type of interval to display (none, confidence, prediction, both)
conf.level: confidence level of the interval
main: a custom title for the graph
xlim: custom limits for the x axis
ylim: custom limits for the y axis
points: whether the scatterplot points should be displayed
cross: whether a cross at the mean levels should be displayed
col: color of the regression plot
values: whether the intervals should be labeled with their values
digits: the specified number of decimal places
add: whether the plot should be added to an existing plot

Value

The returned plot contains the following components:

Est: the regression line
LL: the lower limits of the intervals for the regression line
UL: the upper limits of the intervals for the regression line
