\description{
Method to add edges between RedeR containers. This method adds non-nested assignments, in contrast to the default behavior that builds nested associations to-and-from containers.
}

\usage{
addEdgeBetweenContainers(obj, containerA, containerB )
}

\arguments{
  \item{obj}{Object of RedPort Class. }
  \item{containerA}{<string>}
  \item{containerB}{<string>}  
}

\value{
Add graph objects.
}
