coef {stats} | R Documentation |
coef
is a generic function which extracts model coefficients
from objects returned by modeling functions. coefficients
is
an alias for it.
coef(object, ...) coefficients(object, ...)
object |
an object for which the extraction of model coefficients is meaningful. |

other arguments. |
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
).
Coefficients extracted from the model object object
.
For standard model fitting classes this will be a named numeric vector.
For "maov"
objects (produced by aov
) it will be a matrix.
