Usage

## S3 method for class 'residualDiagnostics'
plot(x, y, plot = TRUE, ask = TRUE, ncol, ...)

Arguments

y	Included to match the generic. Not used.
plot	A logical value whether or not to plot the results or simply return the graphical objects.
ask	A logical whether to ask before changing plots. Only applies to interactive environments.
ncol	The number of columns to use for plots. Missing by default which means individual plots are created. If specified, plots are put together in a grid.
...	Included to match the generic. Not used.

Value

a list including plots of the residuals, residuals versus fitted values

Examples

testm <- stats::lm(mpg ~ hp * factor(cyl), data = mtcars)
testm <- stats::lm(mpg ~ factor(cyl), data = mtcars)

md <- residualDiagnostics(testm, ev.perc = .1)

plot(md, plot = FALSE)$ResFittedPlot
plot(md, ncol = 2)

## clean up
rm(testm, md)
