\title{Class "AgNode": A class to describe a node for a Ragraph object}
\description{This class is used to represent nodes for the
  \code{Ragraph} class.  One can retrieve various pieces of information
  as well as draw them.}
\section{Objects from the Class}{
Objects can be created by calls of the form \code{new("AgNode", ...)}.
}
\section{Slots}{
  \describe{
    
    \item{\code{center}:}{Object of class \code{"xyPoint"}: The center
      point of the node}
    
    \item{\code{name}:}{Object of class \code{"character"}: The name of
      the node, used to reference it}
    
    \item{\code{txtLabel}:}{Object of class \code{"AgTextLabel"}: Label
      for this edge}
    
    \item{\code{height}:}{Object of class \code{"integer"}: Height of
      the node in points}
    
    \item{\code{rWidth}:}{Object of class \code{"integer"}: The right
      half of the node in points.}
    
    \item{\code{lWidth}:}{Object of class \code{"integer"}: The left
      half of the node in points.}

      color of the node.}
    
    \item{\code{fillcolor}:}{Object of class \code{"character"}: The
      color to fill in the node with.}
    
    \item{\code{shape}:}{Object of class \code{"character"}: The shape
      of the node.}
    
    \item{\code{style}:}{Object of class \code{"character"}: The style
      of the node.}
