\title{Merge out-edges between connected containers and transfers edges from nodes to containers. }

\description{
Method to assign out-edges to containers in an active RedeR session. This method transfers edges from nodes to the respective containers.
}

\usage{
mergeOutEdges(obj,...)
}

\arguments{
  \item{obj}{Object of RedPort Class. }
  \item{...}{ Additional arguments passed to RedeR application. } 
}

\details{       
Additional arguments: 
\describe{
   \item{rescale}{Logical value. Whether to rescale the out-edge width to fit container size limits; if false, it will run a simple sum (default=TRUE). }
   \item{lb}{Custom lower bound to rescale edge width (default=NULL) <numerics>. }
   \item{ub}{Custom upper bound to rescale edge width between containers (default=NULL) <numerics>. }
   \item{nlev}{Number of levels to be merged in the hierarchy (default=1) <integer>. }
}
}

\value{
Add/change edge assigments.
}
