    \item{}{\code{xtabs(formula = ~., data, subset, na.action, 
        exclude = c(NA, NaN), drop.unused.levels = FALSE)}:
      Like the original \code{\link{xtabs}}, except \code{data} is a
      \code{DataTable}.

  \code{\linkS4class{DataTable}} for general manipulation,
  \code{\linkS4class{DataFrame}} for an implementation that mimics
  \code{data.frame}.
