plotDiagnosticsLMER: Plot Diagnostics for an lmer model
Description
This function creates a number of diagnostic plots
from lmer models. It relies heavily on the testdistr
function.
Usage
plotDiagnosticsLMER(object, plot = TRUE, ev.perc = 0.001, ask = TRUE,
ncol = 1)
Arguments
object
A fitted model object, either of class merMod from
the lme4 package or merModLmerTest from the lmerTest package.
plot
A logical value whether or not to plot the results or
simply return the graaphical objects.
ev.perc
A real number between 0 and 1 indicating the
proportion of the theoretical distribution beyond which
values are considered extreme values (possible outliers).
Defaults to .001.
ask
A logical whether to ask before changing plots.
Only applies to interactive environments.
ncol
The number of columns to use for interactive plots
Must be either 1 or 2. Defaults to 1.
Value
a list including plots of the residuals,
residuals versus fitted values, and one list for
plots of all random effects and finally a data table with
any extreme values identified
