The Glucose2
data frame has 196 rows and 4 columns.
This data frame contains the following columns:
a factor with levels A
to G
a factor with levels
1
2
indicating the occasion in which the experiment was conducted.
a numeric vector giving the time since alcohol ingestion (in min/10).
a numeric vector giving the blood glucose level (in mg/dl).
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.
