\title{Assign Values to Coefficients}
\usage{
coef(object, ...) <- value

coefficients(object, ...) <- value
}
\alias{coef<-}
\alias{coefficients<-}
\arguments{
 \item{object}{any object representing a fitted model, or, by default,
   any object with a \code{coef} component.}
 \item{...}{some methods for this generic function may require
   additional arguments.}
 \item{value}{a value to be assigned to the coefficients associated with
   \code{object}.}
}
\description{
  This function is generic; method functions can be written to handle
  specific classes of objects. Classes which already have methods for
  this function include all \code{"\link{pdMat}"},
  \code{"\link{corStruct}"} and \code{"\link{varFunc}"} classes,
  \code{"\link{reStruct}"}, and \code{"modelStruct"}.
  
  \code{coefficients<-} is an \emph{alias} for \code{coef<-}.
}
\value{
  will depend on the method function; see the appropriate documentation.
