On this R-data statistics page, you will find information about the pistonrings data set which pertains to Piston Rings Failures . The pistonrings data set is found in the HSAUR R package. You can load the pistonrings data set in R by issuing the following command at the console data("pistonrings"). This will load the data into a variable called pistonrings. If R says the pistonrings data set is not found, you can try installing the package by issuing this command install.packages("HSAUR") 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 pistonrings R data set. The size of this file is about 70 bytes.
Piston Rings Failures
Number of failures of piston rings in three legs of four steam-driven compressors.
A two-way classification, see
The data are given in form of a
table. The table gives the number of piston-ring failures in each of three legs of four steam-driven compressors located in the same building. The compressors have identical design and are oriented in the same way. The question of interest is whether the two classification variables (compressor and leg) are independent.
