effects(object, \dots)
effects.lm(object, set.sign=FALSE)

 \item{object}{list; typically, the result of a model fitting function
   such as \code{\link{lm}}}
 \item{set.sign}{logical ~~Describe \code{set.sign} here~~ }
}
\description{
  Returns (orthogonal) effects from a fitted (generalized) regression
  model.  In case of a full rank \eqn{n \times p}{n * p}
  \code{\link{model.matrix}}, the first \eqn{p} effects correspond to
  coefficients and the remaining \eqn{n-p} ones to residuals.

}
\value{
  A (named) numeric vector of the same length as
  \code{\link{residuals}}.  The first \eqn{p} values are labeled
  according to the corresponding coefficients, the remaining ones are
  unlabeled.

  The result currently has \code{\link{class}} \code{"coef"}.
