The
Puromycin
data frame has 23 rows representing the measurement of
initial velocity of a biochemical reaction for 6 different
concentrations of substrate and two different cell treatments. Most
of the concentration levels were tried twice. All of the data is numeric.
This data frame contains the following variables (columns):
John M. Chambers and Trevor J. Hastie, (1992) Statistical Models in S,
Wadsworth and Brooks, Pacific Grove, CA, pg. 425.
The data are from a biochemical experiment where the initial velocity of a reaction was
measured for different concentrations of the substrate.
Data are from two runs, one on cells treated with the drug Puromycin,
the other on cells without.
