lmList Fit from a groupedData Object

Usage

lmList(object, data, groups, level, na.action, pool)

Arguments

object a data frame inheriting from class{groupedData}.
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 on lmList.

Description

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. See the documentation on lmList.formula for a description of that function.

Value

a list of lm objects with as many components as the number of groups defined by groups. 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.
