Extract Model Residuals
Description
residuals is a generic function which extracts model residuals
from objects returned by modeling functions.
resid is an alias for residuals,
abbreviated to encourage users to access object components through
an accessor function rather than by directly referencing an object
slot.
All object classes which are returned by model fitting functions
should provide a residuals method. (Note that the method is
for ‘residuals’ and not ‘resid’.)
Methods can make use of naresid methods to compensate
for the omission of missing values. The default, nls and
smooth.spline methods do.
Usage
residuals(object, ...)
resid(object, ...)
Arguments
object |
an object for which the extraction of model residuals is meaningful. |
... |
other arguments. |
Value
Residuals extracted from the object object.
