\title{Define Point Process Model for Metropolis-Hastings Simulation.}
\description{
  Builds a description of a point process model
  for use in simulating the model by the Metropolis-Hastings
  algorithm. 
}
\usage{
  rmhmodel(...)
}
\arguments{
  \item{\dots}{Arguments specifying the point process model
    in some format.
  }
}
\value{
  An object of class \code{"rmhmodel"}, which is essentially
  a list of parameter values for the model.
  
  There is a \code{print} method for this class, which prints
  a sensible description of the model chosen.
}
\details{
  Simulated realisations of many point process models
  can be generated using the Metropolis-Hastings algorithm
  \code{\link{rmh}}. The algorithm requires the model to be specified
  in a particular format: an object of class \code{"rmhmodel"}.

  The function \code{\link{rmhmodel}} takes a
  description of a point process model in some other format, and
  converts it into an object of class \code{"rmhmodel"}.
  It also checks that the parameters of the model are valid.

  The function \code{\link{rmhmodel}} is generic, with methods
  for
  \describe{
    \item{fitted point process models:}{
      an object of class \code{"ppm"}, obtained by a call to the
      model-fitting function \code{\link{ppm}}.
      See \code{\link{rmhmodel.ppm}}.
    }
    \item{lists:}{
      a list of parameter values in a certain format.
      See \code{\link{rmhmodel.list}}.
    }
    \item{default:}{
      parameter values specified as separate arguments to \code{\dots}.
      See \code{\link{rmhmodel.default}}.
    }
  }
