residuals.lmList: Extract lmList Residuals

Description

The residuals are extracted from each lm component of object and arranged into a list with as many components as object, or combined into a single vector.

Usage

residuals(object, type, subset, asList)

Arguments

object

an object inheriting from class lmList, representing a list of lm objects with a common model.

subset

an optional character or integer vector naming the lm components of object from which the residuals are to be extracted. Default is NULL, in which case all components are used.

type

an optional character string specifying the type of residuals to be extracted. Options include "response" for the "raw" residuals (observed - fitted), "pearson" for the standardized residuals (raw residuals divided by th

asList

an optional logical value. If TRUE, the returned object is a list with the residuals split by groups; else the returned value is a vector. Defaults to FALSE.

Value

• a list with components given by the residuals of each lm component of object, or a vector with the residuals for all lm components of object.
