\title{Class \code{RMmodel}}
\description{ Class for \pkg{RandomField}'s representation of explicit
 covariance models 
}


\section{Creating Objects}{
 Objects are created by calling a function of class
 \code{\link[=RMmodelgenerator-class]{RMmodelgenerator}}
}

\section{Slots}{
 \describe{
 \item{\code{call}:}{language object; the function call by which the
 object was generated} 
 \item{\code{name}:}{character string; nickname of the model, name of
 the function by which the object was generated} 
 \item{\code{submodels}:}{list; contains submodels (if existent)} 
 \item{\code{par.model}:}{list; conatins model specific arguments} 
 \item{\code{par.general}:}{list of 4; contains the four standard
 arguments \code{var}, \code{scale}, \code{Aniso} and \code{proj} that
 can be given for any model; if not specified by the user, the string
 \code{"RFdefault"} is inserted}
 }

\section{Methods}{
 \describe{
 \item{+}{\code{signature(x = "RMmodel")}: allows to sum up
 covariance models; internally calls \command{\link{RMplus}}.}
 \item{*}{\code{signature(x = "RMmodel")}: allows to multiply
 covariance models; internally calls \command{\link{RMmult}}.}
 \item{plot}{\code{signature(x = "RMmodel")}: gives a plot of the
 covariance function or of the variogram model, for more details see
 \command{\link{plot-method}}.}
 \item{points}{\code{signature(x = "RMmodel")}: adds a covariance plot to
 an existing plot, for more details see
 \command{\link{plot-method}}.}
 \item{lines}{\code{signature(x = "RMmodel")}: adds a covariance plot to
 an existing plot, for more details see
 \command{\link{plot-method}}.}
 \item{str}{\code{signature(x = "RMmodel")}: as the usual
 \code{\link[utils]{str}}-method for S4 objects but where only those
 entries of the 
 'par.general'-slot are shown that contain values different from
 \code{'RFdefault'}}
 \item{show}{\code{signature(x = "RMmodel")}: returns the structure
 of \code{x}}
 \item{print}{\code{signature(x = "RMmodel")}: identical with
 \command{show}-method, additional argument is \code{max.level}}
 \item{[}{\code{signature(x = "RMmodel")}: enables accessing
 the slots via the \code{"["}-operator, e.g. \code{x["par.general"]}}
 \item{[<-}{\code{signature(x = "RMmodel")}: enables replacing
 the slots via the \code{"["}-operator}
 
 }

# Compare:
model <- RMexp(scale=2) + RMnugget(var=3)
str(model)  ## S4 object as default in version 3 of RandomFields

model <- summary(model)
str(model)  ## list style as in version 2 of RandomFields
            ## see also 'spConform' in 'RFoptions' to make this style
            ## the default
