 \title{Seed for the MCMC}
 \description{
   Setting a seed is useful for reproducing MCMC chains
 }
 \usage{
 seed(object)
 seed(object) <- value
 }
 \arguments{
   \item{object}{ An object of \code{XdeParameter} or \code{XdeMcmc} }
   \item{value}{Numeric or integer}
 }
 \details{
   
   The seed stored in the slot of an object of class \code{XdeParameter}
   and an object of class \code{XdeMcmc} are useful in different ways.
   For the \code{XdeParameter} class, the seed indicates what seed was
   used to initialize an MCMC chain.  By contrast, an object of class
   \code{XdeMcmc} contains a seed that would be useful for running
   additional iterations -- the seed here is guaranteed to be different
   from the seed that was used to initiate the MCMC.
