Extract Model Coefficients
Description
coef is a generic function which extracts model coefficients
from objects returned by modeling functions. coefficients is
an alias for it.
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.
