Plot a random.effects.lmList Object
Usage
plot(object, outer, ...)
Arguments
object
|
an object inheriting from class
random.effects.lmList , representing the estimated coefficients or
estimated random effects for the lmList object from which it was
produced.
|
outer
|
an optional one-sided formula specifying the grouping
structure to be used for displaying the random effects
(coefficients). Single factors (~g ) or crossed factors
(~g1*g2 ) are allowed. Default is NULL , in which case
the row names of the random effects (coefficients) are used.
|
...
|
optional arguments passed to the Trellis dotplot
function.
|
Description
A Trellis dot-plot of the random effects is generated, with a different
panel for each random effect (coefficient). Rows in the dot-plot are
determined by the outer
argument (if not missing) or by the row
names of the random effects (coefficients). If a single factor is
specified in outer
, its levels determine the dot-plot rows
(with possibly multiple dots per row); otherwise, if outer
specifies a crossing of factors, the dot-plot rows are determined by
all combinations of the levels of the individual factors in the
formula. The Trellis function dotplot
is used in this method
function.Value
a Trellis dot-plot of the estimated random-effects (coefficients).Note
This function requires the trellis
library.Author(s)
