\title{Extract gnls Coefficients}
\usage{
\method{coef}{gnls}(object, \dots)
}
\alias{coef.gnls}
\arguments{
 \item{object}{an object inheriting from class \code{"\link{gnls}"}, representing
   a generalized nonlinear least squares fitted model.}
 \item{\dots}{some methods for this generic require additional
    arguments.  None are used in this method.} 
}
\description{
  The estimated coefficients for the nonlinear model represented by
  \code{object} are extracted. 
}
\value{
  a vector with the estimated coefficients for the nonlinear model
  represented by \code{object}.
