Description:

     The 'Indometh' data frame has 66 rows and 3 columns of data on the
     pharmacokinetics of indomethicin.

Usage:

     Indometh

Format:

     This data frame contains the following columns:

     Subject an ordered factor with containing the subject codes.  The
          ordering is according to increasing maximum response.

     time a numeric vector of times at which blood samples were drawn
          (hr).

     conc a numeric vector of plasma concentrations of indomethicin
          (mcg/ml).
