| coef | 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, ...) ## Default S3 method: coef(object, complete = TRUE, ...) ## S3 method for class 'aov' coef(object, complete = FALSE, ...)
object |
an object for which the extraction of model coefficients is meaningful. |
complete |
for the default (used for |
... |
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.)
The "aov" method does not report aliased coefficients (see
alias) by default where complete = FALSE.
The complete argument also exists for compatibility with
vcov methods, and coef and aov methods for
other classes should typically also keep the complete = *
behavior in sync. By that, with p <- length(coef(obj, complete = TF)),
dim(vcov(obj, complete = TF)) == c(p,p) will be fulfilled for both
complete settings and the default.
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.
