\title{Class \code{ore.factor}}
\description{
  The \code{ore.factor} class represents \code{\link[base]{factor}} data
  columns in Oracle R Enterprise.
}

  \describe{
    \item{}{
      \code{\link[base]{interaction}(..., sep = ".")}: 
      Returns an \code{ore.factor} object containing the combination of
      the values in arguments \code{...}.
    }
    \item{}{
      \code{\link[base]{levels}(x)}:
      Returns a \code{\link[base]{character}} vector containing the
      factor levels.
    }
    \item{}{
      \code{\link[base]{nlevels}(x)}:
      Returns an \code{\link[base]{integer}} value containing the number
      of factor levels.
    }
    \item{}{
      \code{\link[base]{summary}(object, maxsum = 100, ...)}:
      Returns a tabular summary of the \code{ore.factor} object.
    }
  }
}
\details{
  The levels of \code{ore.factor} objects are not managed as a lookup
  table the same way that \code{\link[base]{factor}} objects
  are. Instead the levels for \code{ore.factor} objects are equivalent
  to \code{sort(unique(as.character(x)))}.
