You can load the PigFeed data set in R by issuing the following command at the console data("PigFeed"). This will load the data into a variable called PigFeed. If R says the PigFeed 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.

Effects of additives to pig feed on weight gain


A dataset with 12 observations on the following 3 variables.

WgtGain Daily wight gain (hundredths of a pound over 1.00)
Antibiotic Antibiotic in the feed? No or Yes
B12 Vitamin B12 in the feed? No or Yes


A scientist in Iowa was interested in additives to standard pig chow that might increase the rate at which the pigs gained weight. Two factors of interest were vitamin B12 and antibiotics. To perform the experiment, the scientist randomly assigned 12 pigs, three to each of the diet combinations (Antibiotic only, B12 only, both, and neither).


Data are found in Statistical Methods by George W. Snedecor and William G. Cochran (1967). Ames, IA: The Iowa State University Press.
