Glucose Levels Following Alcohol Ingestion

Description:

     The 'Glucose2' data frame has 196 rows and 4 columns.

Format:

     This data frame contains the following columns:

     Subject a factor with levels '1' to '7' identifying the subject
          whose glucose level is measured. 

     Date a factor with levels '1'  '2' indicating the occasion in
          which the experiment was conducted.

     Time a numeric vector giving the time since alcohol ingestion (in
          min/10).

     glucose a numeric vector giving the blood glucose level (in
          mg/dl).

Details:

     Hand and Crowder (Table A.14, pp. 180-181, 1996) describe data on
     the blood glucose levels measured at 14 time points over 5 hours
     for 7 volunteers who took alcohol at time 0. The same experiment
     was repeated on a second date with the same subjects but with a
     dietary additive used for all subjects.
