R Dataset / Package boot / calcium
On this Picostat.com statistics page, you will find information about the calcium data set which pertains to Calcium Uptake Data. The calcium data set is found in the boot R package. Try to load the calcium data set in R by issuing the following command at the console data("calcium"). This may load the data into a variable called calcium. If R says the calcium data set is not found, you can try installing the package by issuing this command install.packages("boot") and then attempt to reload the data with library("boot") followed by data("calcium"). Perhaps strangley, if R gives you no output after entering a command, it means the command succeeded. If it succeeded you can see the data by typing calcium at the command-line which should display the entire dataset.
If you need to download R, you can go to the R project website. You can download a CSV (comma separated values) version of the calcium R data set. The size of this file is about 345 bytes.
Calcium Uptake Data
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.
