\begin{Description}\relax
Create a profiler object for the model object \code{fitted}.\end{Description}
\begin{Usage}
\begin{verbatim}
profiler(fitted, ...)
\end{verbatim}
\end{Usage}
\begin{Arguments}
\begin{ldescription}
\item[\code{fitted}] the original fitted model object.
\item[\code{...}] Additional parameters. See documentation on individual
methods.
\end{ldescription}
\end{Arguments}
\begin{Value}
An object of class \code{"profiler"} which is a list with function
elements
\begin{ldescription}
\item[\code{getFittedPars()}] the parameters in \code{fitted}

\item[\code{setDefault(varying, params)}] this is used for changing the default settings for
profiling. In absence of both parameters, the default is set
to the original fitted parameters with all parameters
varying. The arguments are

\code{varying}: a logical, integer or character vector
giving parameters to be varied.
\code{params}: the default value at which profiling is to
take place.

\item[\code{getProfile(varying, params)}] this can be used in conjunction with \code{setDefault}
without any arguments. Alternatively, the parameters to be
varied and the values for fixed parameters can be specified
using the arguments. The arguments are

\code{varying}: a logical vector giving parameters to be
varied. This can be omitted if params is a named list or
numeric vector.

\code{params}: values for parameters to be held fixed.

It returns a list with elements

\code{parameters}: the parameter values for the profiled
optimum.

\code{fstat}: a profile statistics. See individual methods
for details.

\code{varying}: a logical vector indicating parameters
which were varied.
