| residuals.lmList {nlme} | R Documentation |
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.
## S3 method for class 'lmList': residuals(object, type, subset, asList, ...)
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 the estimated
residual standard error) using different standard errors for each
lm fit, and "pooled.pearson" for the standardized
residuals using a pooled estimate of the residual standard
error. Partial matching of arguments is used, so only the first
character needs to be provided. Defaults to "response".
|
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.
|
... |
some methods for this generic require additional arguments. None are used in this method. |
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.
