coef is a generic function which extracts model coefficients
from objects returned by modeling functions.
an alias for it.
coef(object, …) coefficients(object, …) # S3 method for default coef(object, complete = TRUE, …) # S3 method for aov coef(object, complete = FALSE, …)
an object for which the extraction of model coefficients is meaningful.
Coefficients extracted from the model object
For standard model fitting classes this will be a named numeric vector.
"maov" objects (produced by
aov) it will be a matrix.
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
"aov" method does not report aliased coefficients (see
alias) by default where
complete = FALSE.
complete argument also exists for compatibility with
vcov methods, 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.
