       r: Indicator of the presence of calcium oxalate crystals. 

 gravity: The specific gravity of the urine. 

      ph: The pH reading of the urine. 

    osmo: The osmolarity of the urine. Osmolarity is proportional to
          the concentration of molecules in solution. 

    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 determine if
     certain physical characteristics of the urine might be related to
     the formation of calcium oxalate crystals.
