\title{Fitted Values and Residuals from Smoothing Spline ANOVA Fits}
\description{
    Methods for extracting fitted values and residuals from smoothing
    spline ANOVA fits.
}
\usage{
\method{fitted}{ssanova}(object, ...)
\method{residuals}{ssanova}(object, ...)

\method{fitted}{gssanova}(object, ...)
\method{residuals}{gssanova}(object, type="working", ...)
}
\arguments{
    \item{object}{Object of class \code{"ssanova"} or \code{"gssanova"}.}
    \item{type}{Type of residuals desired, with two alternatives
      \code{"working"} (default) or \code{"deviance"}.}
    \item{...}{Ignored.}
}
\details{
    The fitted values for \code{"gssanova"} objects are on the link
    scale, so are the \code{"working"} residuals.
