\begin{Description}\relax
These functions are all \code{\LinkA{methods}{methods}} for class \code{glm} or
\code{summary.glm} objects.
\end{Description}
\begin{Usage}
\begin{verbatim}
## S3 method for class 'glm':
family(object, ...)

## S3 method for class 'glm':
residuals(object, type = c("deviance", "pearson", "working",
                           "response", "partial"), ...)
\end{verbatim}
\end{Usage}
\begin{Arguments}
\begin{ldescription}
\item[\code{object}] an object of class \code{glm}, typically the result of
a call to \code{\LinkA{glm}{glm}}.
\item[\code{type}] the type of residuals which should be returned.
The alternatives are: \code{"deviance"} (default), \code{"pearson"},
\code{"working"}, \code{"response"}, and \code{"partial"}.
\item[\code{...}] further arguments passed to or from other methods.
\end{ldescription}
\end{Arguments}
\begin{Details}\relax
The references define the types of residuals: Davison \& Snell is a
good reference for the usages of each.

The partial residuals are a matrix of working residuals, with each
column formed by omitting a term from the model.
