       r: Indicator of the presence of calcium oxalate crys-
          tals.

 gravity: The specific gravity of the urine.

      ph: The pH reading of the urine.

    osmo: The osmolarity of the urine. Osmolarity is propor-
          tional to the concentration of molecules in solu-
          tion.

    cond: The conductivity of the urine.  Conductivity is
          proportional to the concentration of charged ions
          in solution.

    urea: The urea concentration in millimoles per litre.

    calc: The calcium concentration in millimoles per litre.

     The `urine' data frame has 79 rows and 7 columns.

     79 urine specimens were analyzed in an effort to deter-
     mine if certain physical characteristics of the urine
     might be related to the formation of calcium oxalate
     crystals.
