R Dataset / Package Stat2Data / ChemoTHC


On this R-data statistics page, you will find information about the ChemoTHC data set which pertains to ChemoTHC. The ChemoTHC data set is found in the Stat2Data R package. You can load the ChemoTHC data set in R by issuing the following command at the console data("ChemoTHC"). This will load the data into a variable called ChemoTHC. If R says the ChemoTHC data set is not found, you can try installing the package by issuing this command install.packages("Stat2Data") and then attempt to reload the data. 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 ChemoTHC R data set. The size of this file is about 88 bytes.

A dataset with 2 observations on the following 4 variables.

R project statistics dataset table
Drug Prochlorperazine or THC
Effective Count of effectrive cases
NotEffective Count of noneffective cases
Patients Number of patients in the treatment


An article in the New England Journal of Medicine described a study on the effectiveness of medications for combatting nausea in patients undergoing chemotherapy treatments for cancer. In the experiment, 157 patients were divided at random into two groups. One group of 78 patients were given a standard antinausea drug called prochlorperazine, while the other group of 79 patients received THC (the active ingredient in marijuana). Both medications were delivered orally and no patients were told which of the two drugs they were taking. The response measured was whether or not the patient experienced relief from nausea when undergoing chemotherapy. Dataset is a 2x2 table of counts.
