Extract Model Coefficents

Usage

coef(x, ...)
coefficients(x, ...)

Arguments

x an object for which the extraction of model coefficients is meaningful.
... other arguments.

Description

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

All object classes which are returned by model fitting functions should provide a coef method. (Note that method is `coef' and not `coefficients'.)

Value

Coefficients extracted from the model object x.

See Also

fitted.values and residuals for related methods; glm, lm for model fitting.

Examples

x <- 1:5; coef(lm(c(1:3,7,6) ~ x))
