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.For standard model fitting classes this will be a named numeric vector.
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).
fitted.values and residuals for related methods;
glm, lm for model fitting.
x <- 1:5; coef(lm(c(1:3, 7, 6) ~ x))
