R Dataset / Package MASS / coop
On this Picostat.com statistics page, you will find information about the coop data set which pertains to Co-operative Trial in Analytical Chemistry. The coop data set is found in the MASS R package. Try to load the coop data set in R by issuing the following command at the console data("coop"). This may load the data into a variable called coop. If R says the coop data set is not found, you can try installing the package by issuing this command install.packages("MASS") and then attempt to reload the data with library("MASS") followed by data("coop"). 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 coop 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 coop R data set. The size of this file is about 4,922 bytes.
Co-operative Trial in Analytical Chemistry
Seven specimens were sent to 6 laboratories in 3 separate batches and each analysed for Analyte. Each analysis was duplicated.
This data frame contains the following columns:
