\name{RMid}
\alias{RMid}
\title{Identical Model}
\description{
  \command{RMid} is the identical operator
  for objects of class \code{\link[=RMmodel-class]{RMmodel}}
 }
 \usage{
RMid(phi, vdim, var, scale, Aniso, proj)
}

\arguments{
 \item{phi}{covariance function of class \code{\link[=RMmodel-class]{RMmodel}}.}
 \item{vdim}{for internal purposes}
 \item{var,scale,Aniso,proj}{optional arguments; same meaning for any
 \command{\link{RMmodel}}. If not passed, the above
 covariance function remains unmodified.}
}

 
\value{
 \command{\link{RMid}} returns an object of class \code{\link[=RMmodel-class]{RMmodel}}

}
