coef
Extract Model Coefficients
coef
is a generic function which extracts model coefficients
from objects returned by modeling functions. coefficients
is
an alias for it.
 Keywords
 models, regression
Usage
coef(object, ...)
coefficients(object, ...)
Arguments
 object
 an object for which the extraction of model coefficients is meaningful.
 ...
 other arguments.
Details
All object classes which are returned by model fitting functions
should provide a coef
method or use the default one.
(Note that the method is for coef
and not coefficients
.)
Class "aov"
has a coef
method that does not report
aliased coefficients (see alias
).
Value

Coefficients extracted from the model object
object
.For standard model fitting classes this will be a named numeric vector.
