     The 'calcium' data frame has 27 rows and 2 columns.

     Howard Grimes from the Botany Department, North Carolina State
     University, conducted an experiment for biochemical analysis of
     intracellular storage and transport of calcium across plasma
     membrane.  Cells were suspended in a solution of radioactive
     calcium for a certain length of time and then the amount of
     radioactive calcium that was absorbed by the cells was measured. 
     The experiment was repeated independently with 9 different times
     of suspension each replicated 3 times.

     This data frame contains the following columns:


     '_t_i_m_e' The time (in minutes) that the cells were suspended in the
          solution.

     '_c_a_l' The amount of calcium uptake (nmoles/mg).
