Methods for function \code{findFreqTerms} in package \pkg{tm}.

\section{Methods}{
  \describe{
    \item{object = "TermDocMatrix", lowfreq = "numeric", highfreq =
      "numeric"}{Return those terms from \code{object} which occur more or
      equal often than \code{lowfreq} times and less or equal often than
      \code{highfreq} times. This method works for all numeric
      weightings but is probably most meaningful for the standard term
      frequency (\code{tf}) weighting of \code{object}.

data("crude")
tdm <- TermDocMatrix(crude)
findFreqTerms(tdm, 2, 3)
