coef.lmList: Extract lmList Coefficients

Description

The coefficients of each lm object in the object list are extracted and organized into a data frame, with rows corresponding to the lm components and columns corresponding to the coefficients. Optionally, the returned data frame may be augmented with covariates summarized over the groups associated with the lm components.

Usage

## S3 method for class 'lmList':
coef(object, augFrame, data, which, FUN,
   omitGroupingFactor, \dots)

Value

a data frame inheriting from class coef.lmList with the estimated coefficients for each lm component of object and, optionally, other covariates summarized over the groups corresponding to the lm components. The returned object also inherits from classes ranef.lmList and data.frame.
