  the pharmacokinetics of indometacin (or, older spelling,
  \sQuote{indomethacin}).
}
\usage{Indometh}
\format{
  An object of class
  \code{c("nfnGroupedData", "nfGroupedData", "groupedData", "data.frame")}
  containing the following columns:
  \describe{

      ordering is according to increasing maximum response.
    }
    \item{\code{time}}{
      a numeric vector of times at which blood samples were drawn (hr).
    }
    \item{\code{conc}}{
      a numeric vector of plasma concentrations of indometacin (\abbr{mcg}/ml).

  This dataset was originally part of package \CRANpkg{nlme}
  \bibcitep{|R:Pinheiro+Bates:2000|Appendix A.12}, and that has
  methods (including for \code{[}, \code{as.data.frame}, \code{plot} and
  \code{print}) for its grouped-data classes.
