\title{Class "AgTextLabel": Represents a graphviz text label}
\description{ This class is used to represent the textlabel object in
  C from the Graphviz library}
\section{Objects from the Class}{
Objects can be created by calls of the form \code{new("AgTextLabel", ...)}.
}
\section{Slots}{
  \describe{
    \item{\code{labelText}:}{Object of class \code{"character"} The
      actual label text}
    \item{\code{labelLoc}:}{Object of class \code{"xyPoint"} The
      location of the label }
    \item{\code{labelJust}:}{Object of class \code{"character"} The
      justification of the label }
    \item{\code{labelWidth}:}{Object of class \code{"integer"} The width
      of the label}
    \item{\code{labelColor}:}{Object of class \code{"character"} The
      color to print the label} 
    \item{\code{labelFontsize}:}{Object of class \code{"numeric"} The
      font size for the label}
