The response variable and primary covariate in
formula(object)
are used to construct the linear model formula. This formula
and the
groupedData object are passed as the
object and
data
arguments to
lmList.formula, together with any other
additional arguments in the function call.
USAGE:
lmList(object, data, level, na.action, pool)
REQUIRED ARGUMENTS:
object
a data frame inheriting from class
groupedData.
OPTIONAL ARGUMENTS:
data
this argument is included for consistency with the generic
function. It is ignored in this method function.
other arguments
identical to the arguments in the generic
function call. See the documentation for
lmList.
VALUE:
a list of
lm objects with as many components as the number of
groups defined by the grouping factor. Generic functions such as
coef
,
fixed.effects,
lme,
pairs,
plot
,
predict,
random.effects,
summary,
and
update have methods that can be applied to an
lmList
object.
